A revision of Orthostichella (Neckeraceae)

Abstract Orthostichella Müll. Hal. is a genus of nine species (O. capillicaulis, O. hexasticha, O. longinervis, O. muelleri, O. pachygastrella, O. pandurifolia, O. rigida, O. versicolor and O. welwitschii) found only in tropical and subtropical regions of the New World and Africa. One species (O. hexasticha) is restricted to the Caribbean, one (O. pachygastrella) is found only in the continental regions of the New World, two (O. capillicaulis and O. pandurifolia) are restricted to continental Africa, and one (O. longinervis) is found only in Madagascar and the Mascarene Islands. The other species occur in both Africa and the New World. Orthostichella is predominantly epiphytic and often grows in dense, pendent masses. It has a complex morphology with creeping primary stems or stolons, and erect or pendent, stipitate or evenly foliose secondary stems that are irregularly branched. It lacks a stem central strand and its axillary hairs are usually reddish throughout. Its branches often end in filiform attenuations or stolons. The stolons, stems and branches can abruptly transform from one structure to another, or they can seamlessly intergrade one into another. The leaves are often spirally ranked, they have elongate, smooth, firm-walled leaf cells and weakly developed alar cells. The costae in Orthostichella are wildly variable. In some species most leaves are ecostate, however, some leaves can be found with double or single costae. In other species most leaves have a single or double costa, but ecostate leaves can also be found. In one species (O. longinervis) the leaves always have long, single, subpercurrent costae. Orthostichella has elongate-flexuose, roughened setae, ovoid to short-cylindrical capsules, long-rostrate opercula and mostly hairy, cucullate calyptrae. The Orthostichella peristome is diplolepideous and reduced. Exostomes and endostomes are yellowish white and nearly the same length. The more or less linear exostome teeth are lightly, horizontally striate on the dorsal (outer) surface at base. The endostome has a low basal membrane with filamentous, narrowly perforate segments and cilia are usually absent. Orthostichella appears best placed in the Neckeraceae by virtue of its neckeroid peristome, creeping stolons, stipitate stems with differentiated stipe leaves, foliose pseudoparaphyllia and leaves with weakly developed alar cells. Within the Neckeraceae Orthostichella seems best placed near Porotrichum, but the genus appears isolated by virtue of its non-complanate leaves that are often arranged in spiral rows. Additional new combinations include: Orthostichidium quadrangulare (Schwägr.) n. comb., Orthostichidium pentastichum (Brid.) n. comb. and Hildebrantiella phleoides (Desv. ex Brid.) n. comb.

A review of the moss genus Hypnella

Hypnella is a neotropical genus offour species: H. leptorrhyncha, H. pallescens, H. pilifera, and H. diversifolia. These species can be divided into two groups (H. leptorrhyncha-H. pilifera and H. pallescens-H. diversifolia) in which the members of each group are more or less spatially isolated. The familial affinities of Hypnella lie with the Sematophyllaceae. Neohypnella, difering from Hypnella only by its lack of a furrow on the dorsal surface of the exostome, is placed in the synonymy of Hypnella. A new lectotype for the genus is selected. The genus Hypnella includes pleurocarpous mosses of neotropical distribution characterized by a non-complanate habit, lack of a central strand in the stem, undifferentiated alar cells, long narrow leaf cells with 3-6 papillae over the lumens, double cos- tae, mitrate calyptrae, elongated setae that are pa- pillose to scabrous at the apex, and double peri- stomes marked by transverse striae on the dorsal surface of the exostome and the complete lack of endostomal cilia. In the past Hypnella has usually been aligned with the Hookeriales. The group was first described by Miiller (1851) as a section of Hookeria. MUiller dis- tinguished the section within Hookeria by its long narrow leaf cells and densely imbricate habit that showed no sign of being plano-complanate. Jaeger (1877) gave the section generic status and excluded all species with smooth leaf cells from the group. Jaeger retained Hypnella in his family Hookerieae (sic), a placement Brotherus (1907) followed when he further characterized the genus by its double cos- tae, transversely striate exostome teeth, lack of a central strand in the stem and the absence of en-

The taxonomic status of Hypnella punctata

After reviewing the genus Hypnella, Crosby, Allen and Magill (1985) reduced the number of recognized species from sixteen to four. Of the 12 species not recognized, four were considered of uncertain relationship, since their types had not been examined. The holotype of one of the four species (Hypnella punctata, BM) has now been examined. It is a member of Hypnella, but is distinct from the other four species. The five species of Hypnella may be distinguished in the following key revised from Crosby, Allen and Magill (1985). In its protologue Hampe (1879) astutely compared H. punctata (Fig. 1-6) to Hookeria leptorrhyncha (=Hypnella leptorrhyncha, Fig. 7-14). The two species are very close, indeed identical in a number of leaf characters: serrate apex, obscure border of long narrow more or less smooth cells, narrow leaves and areolation. They differ only in their leaf apices, apical cell lengths, and geography (H. punctata: acute; rounded hexagonal, to 15 Am; southern Brazil and H. leptorrhyncha: long acuminate to piliferous; linear, over 25 Am; throughout the Caribbean and Venezuela).

The Liverworts and Hornworts of Belize

A complete list of the liverworts and hornworts known from Belize, comprising 49 genera and 65 species, is presented. Twenty-two genera and 30 species are new to Belize, and Calypogeia lophocoleoides Steph. is new to Central America. Belize is a small country (22,963 square km) lo- cated on the Caribbean coast of northern Central America at approximately 160 to 181/20 north lati- tude. The northern half of the country is a low-lying limestone plain, while the southern half is domi- nated by the Maya Mountains, a raised peneplain reaching 1,140 m elevation at Doyles Delight. The Maya Mountains may once have formed part of a land connection between northern Central America

On the distribution of Erpodium cubense and Fissidens cryptoneuron, with notes on species ranges

Abstract Erpodium cubense, previously known only from Cuba, was found in the Dominican Republic as misidentified collections of E. domingense. Fissidens cryptoneuron, previously known from tropical Africa and eastern Brazil, is reported from Bolivia. The actual or real range of a species depends upon a number of physical and biological factors. The perceived range of a species approximates the actual range; its propinquity to the actual range is dependent on correct specimen identification and scope of collecting activity.

A Revision of the Genus Lindigia (Musci: Meteoriaceae) in the Neotropics

The genus Lindigia is represented in the neotropics by the single species Lindigia debilis. All other neotropic species previously ascribed to the genus are synonymous with either L. debilis or Rhynchostegiella capillacea (Hornsch.) Visnadi & Allen comb. nov. The genus is retained in Meteoriaceae and positioned between Barbella and Floribundaria. As presently defined, the genus Lindigia consists of epiphytic, frequently pendent mosses restricted to tropical regions of the New World, Africa, and Asia. The genus was established by Hampe in 1862 for the single species L. curtipes. Notable among the features of Hampes new genus were its slender, sparsely branched habit, costate leaves, short-conic, weakly beaked opercula, and papillose exostome
