A new species of Gesneriaceae from the Pacific slopes of the Colombian Andes is described and illustrated. The new species, Drymonia betancurii, is differentiated from other congeners by the following combination of characters: upper leaf surface with papillose-hispid trichomes, dark green and often covered with white spots; lower surface pitted; and corolla lobes orange-red with white to yellow margins.

A New Species

We describe a new species of Leucostethus from Gorgona Island, a small (13 km2) island located 35 km from the Pacific coast of southern Colombia. The new species most resembles L. argyrogaster and L. fugax from western Amazonia at 340–870 m elev. in Peru and Ecuador, with which it shares pale ventral coloration and orange suffusion of the axilla, groin and concealed surfaces of the hind limb, but it is most closely related to L. bilsa from ca. 340 km SW in the southern Chocó at 420–515 m elev., northwestern Ecuador. We report miniscule white spots on the posteroventral surface of the thighs of the new species and, on the basis of our preliminary assessment of their taxonomic distribution, hypothesize that their presence is a synapomorphy of Dendrobatoidea with subsequent losses in a few groups. Given the apparent restriction of the new species to Gorgona Island, it is Vulnerable according to IUCN Red List criteria. In addition to naming the new species, we also propose the following new combinations: L. alacris (Rivero and Granados-Díaz, 1990) comb. nov., L. dysprosium (Rivero and Serna, 2000) comb. nov., and L. yaguara (Rivero and Serna, 1991) comb. nov.

A New Species

The new species Begonia dicressine (sp. nov.) belonging to Begonia section Platycentrum is described. The new species is similar to B. rockii but differs in having petioles with long soft white hairs, plain dark green leaves with irregularly crenate margins, lower surface only with appressed hairs along midrib, and glabrous inflorescences. B. dicressine is distributed in Kachin Province in northern Myanmar in the understory of evergreen and semi-deciduous forests. New records of B. difformis from the same area are also reported, and its distribution and habitat are discussed.

A New Species

Pleurothallis tenuisepala, a new species in subsection Acroniae, is described and compared to Pleurothallis luctuosa with which it has previously been confused. While the two species are superficially similar, they can be very easily distinguished by the size of the flowers, which are approximately 60 mm long in P. tenuisepala versus approximately 29 mm long in P. luctuosa, or the length of the sepals, which are approximately four-times the length of the petals in P. tenuisepala versus less than twice the length of the petals in P. luctuosa. The two species can also be discriminated by their nuclear internal transcribed spacer (nrITS) sequences. Pleurothallis tenuisepala occurs on Isla Gorgona off the Pacific coast of Colombia and on the western slopes of the Cordillera Occidental of the Colombian Andes, while P. luctuosa is restricted to the Cordillera de Tilarán of Costa Rica. Labellar micromorphology of both species is discussed in relation to possible pollination mechanisms. Key words: Acroniae, cryptic species, labellum, morphology, taxonomy

<p>A new species of Drymonia (Gesneriaceae) from the Cordillera Occidental of the Colombian Andes in the department of Antioquia is described and illustrated. The new species, Drymonia squamosa, is distinguished by dense clusters of scales on the petioles, glabrate leaf blades with minute punctations on the lower surface, calyx appearing swollen at base with lanceolate lobes, corolla villous to lanate, and style with glandular trichomes. Additionally, D. squamosa is categorized as vulnerable (VU) based on the IUCN criteria.</p>

Surface Comparison

Study of selected specimens of Gymnomitrion collected by D. G. Long in Yunnan, China, revealed a new species, G. fissum Mamontov et Potemkin, sp. nov., with a fissured leaf surface. Comparison of SEM images of the leaf surface and leaf cross sections shows that the leaf surface of G. fissum is different from that of other known species with a superficially similar leaf surface, i. e. Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula. It has fissures around the cell lumen rather than grids and perforations. Outer cell walls of Gymnomitrion fissum are much thicker than in Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula, and their outer layers tend to be partly or completely caducous. G. fissum is related to the group of species assigned to the former genus Apomarsupella.

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.

A New Species

A new species of Guianacara is described from tributaries of the Essequibo River and the rio Branco in Guyana and northern Brazil. Guianacara dacrya, new species, can be diagnosed from all congeners by the possession of a unique infraorbital stripe and by the shape of the lateral margin of the lower pharyngeal jaw tooth plate. Guianacara dacrya can be further distinguished from G. geayi, G. owroewefi, G. sphenozona and G. stergiosi by the possession of a thin midlateral bar, from G. cuyunii by the possession of dusky branchiostegal membranes and from G. oelemariensis by the possession of two supraneurals. This species differs from most congeners by the presence of white spots on the spiny portion of the dorsal fin, the placement of the midlateral spot, the presence of filaments on the dorsal, anal and in rare cases the caudal-fin and from at least the Venezuelan species by several morphometric variables. Guianacara dacrya is known from the Essequibo, Takutu and Ireng River basins of Guyana and possibly from the rio Uraricoera in the rio Branco basin in Brazil. A key to the species is provided.
