A new species of Graffenrieda (Melastomataceae) from the northern Amazon basin

A new species of Graffenrieda (Melastomataceae: Merianieae) from northern Brazil and southern Venezuela is described. Graffenrieda laevicarpa closely resembles the morphologically variable and complex G. caryophyllea, but can be distinguished based on leaf morphology and pubescence, and by its shiny capsules.     

A new species of Miconia (Melastomataceae, Miconieae) from northeastern Brazil

Miconia caiuia occurs only in the highly endangered submontane moist forests in the states of Alagoas, Pernambuco, and northern Bahia, Brazil. It belongs to Miconia section Miconia subsection Secundiflorae. This new species can be distinguished from other species in this subsection by the lepidote-stellate trichomes on young branches, petioles, inflorescences and hypanthia, leaves with suprabasal nerves and wrinkled/auriculate bases, abaxial leaf surfaces with only sparse trichomes, a 5-locular ovary, and large mature fruits (10–13?×?12–15 mm) with up to 15 seeds, which are 2.5–3.5 mm long.

Seeds and embryos in Sri Lanka (Ceylonese) species of Memecylon, with notes on Spathandra (Melastomataceae)

Seeds and embryos in 12 Ceylonese species of Memecylon are of three types with 1) cotyledons wrinkled and hypocotyl long, 2) cotyledons rolled and hypocotyl short, and 3) cotyledons fleshy and hypocotyl short. The first type is common in Memecylon and it occurs e.g. in M. capitellatum , the type species. The second type is found in M. arnottianum and M. gardneri as well as in some species of Spathandra , an African genus considered to be vaguely defined. The third type is new and it occurs in M. rivulare.     

A new Mecranium (Melastomataceae) from Hispaniola

Mecranium revolutum is described from the Massif de la Hotte of Haiti and compared with three similar species that are also endemic to this interesting region. The lower elevation (1000–1600 m) forests of Parc National Pic Macaya are discussed briefly.     

A new species ofLiparis (Orchidaceae) from India

Liparis indiraii spec. nova from India is close toL. alata A. Rich. andL. atropurpurea Lindl.     

A new species ofThottea (Aristolochiaceae) from India

Thottea ponmudiana sp. nova from Kerala (India) can readily be distinguished from its closest allyTh. siliquosa and all the other known species of the genus by its yellow flowers with purple eyes, deeply lobed perianth with strongly reflexed margins, uniseriate stamens united in three bundles and strongly 4-angled, green, glabrescent fruits.     

Three new Mesoamerican species of Topobea (Melastomataceae)

Three new species ofTopobea are described from species-rich, humid forest environments in Costa Rica and Panama. Discussions, diagnostic illustrations, phenological notes, and a distribution map are provided forTopobea intricata, T. lentii, andT. mephersonii.     

Two new species of Huberia (Melastomataceae: Merianieae) from Brazil

Two new Brazilian species of the genusHuberia,H. carvalhoi andH. consimilis, are described, discussed, and illustrated.Huberia carvalhoi is endemic to Bahia;H. consimilis has a wider distribution, with disjunct populations in Pernambuco, Bahia, and Rio de Janeiro. A key is provided to the three Bahia taxa with some comments on the taxonomic affinities of the two new species.     

A new species of Litsea (Lauraceae) from India

Litsea beei, a new species of Lauraceae from India is described and illustrated. The new species is allied to the Burmese-Malayan species L. myristicaefolia.     

A new species of Ceropegia (Asclepiadaceae) from India

Ceropegia schumanniana , a new species belonging to Asclepiadaceae is described from the Western Ghats of India.     

A new epiphytic blakea (Melastomataceae) from Panama

Blakea wilburiana is described from the low volcanic uplift of El Valle de Anton in central Panama. Hirsute pubescence, papery leaves, and large, thin floral bracts suggest a marked affinity withB. bracteata Gleason of South America. A character tabulation, comparing the two species, is included together with illustrations of the diagnostic morphological features.
