Thyopsiella, and F. grandiclava Steph. and F. orientalis Sande-Lac. of F. subg. Frullania sect. Orientalis.

Key words. Frullania subgenus Frullania, Frullania subgenus Meteoriopsis, Frullania subgenus Thyopsiella, Hepaticae, Asia, nomenclature, taxonomic revision.

INTRODUCTION

Spruce (1884) described the subgenus Meteoriopsis as one of his six subgenera within Frullania, for the inception of species with pendent growth. Since then, many species have been assigned to subg. Meteoriopsis Spruce. Stephani (1911) assigned 53 species from all over the Tropics to this subgenus, including 15 species from tropical Asia and Oceania. In 1924, Stephani described eight further new species in subg. Meteoriopsis, but several of them were subsequently transferred to other subgenera.

Verdoorn (1930) in his treatment of Frullania from the Indomalayan archipelago recognized 11 species in subg. Meteoriopsis including several that were newly assigned to this subgenus. Verdoorn also presented a discussion on the morphological limits of the subgenus, and proposed several characters as being diagnostic for subg. Meteoriopsis, such as stem and branches very long, growing almost unlimited ["Stamm und Hauptäste sehr verlängert, fast unbegrenzt weiter wachsend"]. Characters associated with leaf-lobes, leaf-lobules or leaf bases were not considered.

In 1972, Hattori published the new species Frullania schusterana which he assigned to the subg. Meteoriopsis. He also discussed the merits of Meteoriopsis as a subgenus and suggested that it corresponded with sect. Vaginatae of subg. Thyopsiella Spruce (the latter as subg. "Frullania"). In 1974, however, Hattori accepted Meteoriopsis again as a good subgenus (following Verdoorn 1930) while placing F. schusterana Hatt. in subg. Thyopsiella.

Uribe & Gradstein (2003) redefined F. subg. Meteoriopsis Spruce to include species with two auricles at leaf-base and with leaves convoluted around the stem when dry (not spreading widely when moistened). Frullania peruviana Gottsche was selected as the lectotype of the group. Subsequently, Uribe (2008) monographed subg. Meteoriopsis and accepted seven species in the subgenus, all of them from tropical America (Figure 2, clade 32; Uribe 2008). Species from the Old World previously assigned to subgenus Meteoriopsis were placed in other subgenera or left unclassified. The relationships of subg. Meteoriopsis to other members of the genus Frullania were analyzed based on a phylogenetic analysis of the genus using 36 morphological characters. The analysis showed that subg. Meteoriopsis is monophyletic and sister to the monophyletic subg. Thyopsiella. Together two groups formed a monophyletic group, clade 29, consisting of 2 lineages (Uribe 2008; Fig. 2): the Thyopsiella clade with 3 species (F. atrata, F. brasiliensis, F. intumescens) and the Meteoriopsis clade with 7 species (F. convoluta, F. darwinii, F. dulimensis, F. grandifolia, F. peruviana, F. phalangiflora, F. weberbaueri).

Based on a molecular-phylogenetic analysis of the genus Frullania using four molecular markers, Hentschel et al. (2009) established a much wider subgeneric concept of F. subg. Meteoriopsis which included many previous members of subg. Thyopsiella Spruce, in three different clades. The newly defined subgenus differed from subg. Thyopsiella s.str. (including the type, F. tamarisci) by the lack of ocelli and its tropical distribution. Subgenus Meteoriopsis Spruce was subsumed in a clade named "sect. Intumescentes", containing 6 former members of Thyopsiella (F. aculeata, F. atrata, F. brasiliensis, F. intumescens, F. moritziana, F. pittieri) and 1 of genuine Meteoriopsis (F. peruviana). Thus defined, sect. Intumescentes corresponded with Frullania clade 29 recovered by Uribe (2008) on morphological grounds. However, only 4 species of clade 29 were studied by Hentschel et al. (2009), 3 of the Thyopsiella clade and 1 of the Meteoriopsis clade.

Hentschel et al. (2009) postulated that their sect. Intumescens largely corresponded to the subg. Meteoriopsis as circumscribed by Spruce (1884). This statement is erroneous. Spruce recognized four species in his subgenus Meteoriopsis: F. atrata, F. atrosanguinea, F. peruviana and F. aculeata. Of these, F. aculeata is actually a member of subg. Thyopsiella sensu Spruce, all others belong in subg. Meteoriopsis sensu Spruce (Uribe & Gradstein, 2003; Uribe, 2008; but specimens identified by Spruce as "F. atrata" proved to be misidentified F. peruviana or F. convoluta, and F. atrosanguinea appeared to be a synonym of F. peruviana). In contrast, all species included in sect. Intumescentes by Hentschel et al. (2009) are members of subg. Thyopsiella sensu Spruce with exception of F. peruviana.

Since only 1 out of 7 species of F subg. Meteoriopsis Spruce (sensu Uribe 2008) was studied by Hentschel et al. (2009), sampling in the latter study was too low to decide on the status of this subgenus. Moreover, support of the clade of F subgen. Meteoriopsis in Hentschel et al. (2009) was low (68) compared with the support of other clades, and no morphological characters were provided for the separation of the three sections in Meteoriopsis sensu Hentschel et al. Therefore, I think that it is better to keep using the concept of subgen. Meteoriopsis as defined by Uribe (2008) until more species of this group are analyzed by molecular methods.

The purpose of this present paper is to describe six Asiatic species previously assigned to subg. Meteoriopsis (F. grandiclava, F. orientalis , F. seriatifolia, F. ternatensis, F. trichodes, F. vaginata) and discuss their subgeneric affiliation.

SPECIES DESCRIPTIONS

1. Frullania (subg. Thyopsiella) vaginata (Sw.) Nees, in Gottsche, Lindenberg & Nees, Syn. Hepat. : 465 (1844). Jungermannia vaginata Swartz, Amoenitates Acad. Ed. II, vol. X, App.: 115 (1781); Frullania vaginata Dumort., 1835, Rec. Obs.: 13 (1835), nom. inval. (Art. 32.1 ICBN). Type: Java, without collector (holotype, S!). Fig. 1 A-F

Plants of large size, up to 20 cm long and 0.7 mm wide including leaves, dark reddish to brown, irregularly once or twice pinnate, growing more or less pendent. Branches 1-2 cm long. Stems to 90 µm wide, in cross section. Leaf-lobes remote, ovate-orbicular, obliquely spreading, with strongly incurved ventral margin, plane, ovate, asymmetrical, 740 x 600 µm, apex subacute (short acuminate on branch leaves), dorsal margins dentate, dorsal base auriculate, ventral base not auriculate, insertion line slightly curved. Leaf cells: apical cells 10-12 x 8-9 µm, median cells 12-14 x 9-11 µm, basal cells 23-33 x 8-12 µm, all cells with thick, sinuous walls and with trigones and intermediate thickenings, pale orange, basal ocelli distinct, 10-17 per leaf-lobe. Lobules cylindrical to clavate, 220-230 x 100-110 µm, contiguous and almost parallel to the stem, with arched and crenulate mouth. Stylus composed of a row of 3 uniseriate cells and of a rounded disc of 6-8 cells long and 5 cells wide. Underleaves ovate-rectangular, distant, slightly wider than the stem, 540-560 x 230-240 µm, margins strongly recurved, bifid to 1/3 the length, segments subtriangular, apex acute or acuminate, diverging, base short auriculate, insertion line straight. Branch appendages: first branch underleaf divided to the base into a lanceolate, bifid segment and a saccate segment, first leaf transformed into two saccate lobules. Plants dioicous. Androecia not seen. Gynoecia lateral on primary branches, or terminal on stems, the bracts and bracteoles in three series, bracts unequally bifid, the segments acute or acuminate, margin dentate. Perianth not seen.

Distribution Java, Sumatra. Stephani (1911) reported this species from Borneo and New Guinea, and Menzel (1988) listed the species in his Borneo catalogue based on literature compilation. However, according to Verdoorn (1930) and Hattori (1976a) this species is restricted to Sumatra and Java, and is absent of Borneo and New Guinea.

Comments Verdoorn (1930) assigned F. vaginata to subg. Meteoriopsis, mostly on the basis of its long stems, whereas Hattori (1976a) treated it as a member of Frullania subg. Thyopsiella. Uribe (2008) excluded the species from subg. Meteoriopsis and did not assign it to subgenus by lack of study of the type. Following examination the holotype, I now confirm that the species belongs to subg. Thyopsiella.

2. Frullania (Frullania) orientalis Sande Lac. Nederl. Kruidk. Arch. IV: 94 (1855). Type: Java, Teysmann s. n. (holotype, L!). Fig. 1 G-L

Plants of medium to large size, up to 10 cm long and 2 mm wide including leaves, loosely branching, branch long, to 5 cm long, distant, dark reddish brown to almost black, irregularly pinnate, growing more or less pendent. Stems to 200-500 µm wide in cross section. Leaf-lobes distant, rounded, entire, convolute around the stem when dry and wet, plane, ovate, symmetrical, 1850-1900 x 1550-1575 µm, apex obtuse or rounded, to slightly acute, margins entire, dorsal base auriculate or sometimes subtruncate, ventral base auriculate, auricles sometimes superposing each other, mostly the leaves subtending branches, insertion line arched.

Gynoecia terminal on the stem, the bracts and bracteoles in three series, bracts unequally bifid, the segments acute or acuminate, entire. Perianth pyriform, 500 µm long, with three keels, the ventral keel narrow.

Distribution - New Guinea, Taiwan, Philippines, Sulawesi, Borneo, Java, Vietnam, Malayan Peninsula, Sumatra, Sri Lanka, and other, smaller Asian and Pacific islands (Hattori, 1976b). In addition, the species has been reported from Fiji (Campbell, 1971), China (Yunnan) (Piippo et al., 1998) and India (Parihar, 1962).

Comments - This species was treated by Verdoorn (1930) within a new section "Orientales", along with F. nigricaulis (Reinw., Blume & Nees) Nees. However, Hattori (1972) transferred this species to subg. Frullania ("Trachycolea") sect. Ornitocephalae Verd. Based on study of the type material, I confirm that the species belongs to subg. Frullania. Following Hentschel et al. (2009), the species may be placed in subg. Frullania sect. Orientales.

3. Frullania (subg. Frullania) grandiclava Steph., Sp. Hepat. 4: 676 (1911). Type: New Caledonia, VII 1909, Le Rat s.n. (holotype, G!). Fig. 2 A-H

Distribution - Known only from the type locality from New Caledonia.

Comments: Verdoorn (1930) and Hattori (1977) treated F. grandiclava as a synonym of F. capillaris without justification. In my study I found that F. grandiclava differs from F. capillaris as described by Hattori by its toothed underleaves, leaves longer than wide and leaf-lobules smaller, therefore F. grandiclava is treated here as a separate species, not as a synonym of F. capillaris.

By its underleaves with a toothed margin, lobule with a rostrate mouth and long beak, and perianth with scattered tubercles, F. grandiclava is clearly a member of subg. Frullania sect. Orientalis.

Distribution - Known only from type locality, New Guinea.

Comments - Stephani (1894, 1911) and Uribe (2008) placed this species in subg. Diastaloba, Verdoorn (1930) assigned it to Meteoriopsis and Hattori (1973) to subg. Thyopsiella. Hattori also concluded that F. yulensis Steph. is a synonym of F. seriatifolia. My study of the type specimens confirm the conclusions of Hattori (1973).

Branch appendages: first branch underleaf divided to the base into a lanceolate, bifid segment and a explanate segment, first leaf transformed into one saccate lobule. Plants dioicous. Androecia capitate, on lateral short branches, 1-3 pairs of bracts. Gynoecia lateral on primary branches, or terminal on stems, the bracts and bracteoles in 1-3 series.

Comments: According to Verdoorn (1930) the inclined, triangular stylus (Fig. 3D) is characteristic of this species. The different sizes of the auricles at the dorsal and ventral bases of the leaf-lobe, and the shape of the lobule indicate that the species belongs in subg. Thyopsiella (Verdoorn, 1930; Hattori, 1973).

Distribution - Solomon Islands, New Guinea, Japan, China, Taiwan, Philippines, Borneo, Java, Sumatra, Thailand (Sornsamran & Thaithong, 1995), Myanmar, Sri Lanka (Onraedt, 1981).

Comments: Hattori (1975) suggested that Frullania vaginata and F. vethii may be considered as locally differentiated sibling taxa at a subspecific level. However, my examination of the type specimens indicates that F. vethii is morphologically identical to F. trichodes and should be treated as a synonym of the latter species. Frullania trichodes belongs in subg. Thyopsiella and is close to F. vaginata. The latter species can be distinguished by the dentate leaf margin (mostly on dorsal side), while in F. trichodes the margins of the leaves are entire. Frullania trichodes is very variable in several characters, which is reflected in the high number of synonyms; although its identity is not completely resolved yet, I treat it here as a distinct species.
