A New Species

A new species of Nepenthes—Nepenthes putaiguneung—from the highlands of Sumatra (Indonesia) is described and illustrated. This new species is morphologically similar with N. Singalana from which differs in having narrowly spathulate leaves, more gracile upper pitchers with a finely ribbed peristome, lacking teeth on its inner edge, lid with a basal crest and a short tooth-like triangular appendage near the apex on the underside (not lacking such appendages), the lid glands of lower pitcher confined to the midline (not scattered evenly over the whole surface), and pedicel of lower male flowers usually with minutely short bracteole. N. putaiguneung is also similar to N. mikei but differs in having narrowly spathulate leaves with obtuse apex, lower pitcher with slender infundibulate shape below and cylindrical above, peristome of lower pitcher with short and denser distinct ribs, lid of lower and upper pitcher with a prominent glandular crest at the base of midrib, several distinct glands on the lid of lower pitcher that clustered along the midrib; and pedicel of lower male flowers that usually with minutely short bracteole.

A new species, Smilax hirtellicaulis (Smilacaceae), from southwestern China is described and illustrated. The new species differs from all known Smilax species in its unique tepals, i.e., basally connate in male flowers but separate in female flowers. Phylogenetic analysis supports its species delimitation, and suggests a sister position to the clade of Smilax sect. Heterosmilax which have flowers with connate tepals. Their closest phylogenetic relationship and resembled flower morphology may represent an evolutionary transition from separate to united tepals in Smilax. It thus provides us an ideal model for studying the evolution and development of such an innovative floral trait.

Ruellia anamariae, a new species of Acanthaceae is herein described and illustrated from the municipalities of Parauapebas and São Geraldo do Araguaia, Pará State, Brazil. The new species is recognized by its habit, a shrub up to 5 meters high, by its terminal thyrsus inflorescence, by its greenish-yellow corolla with the expanded portion of the tube suburceolate, strongly revolute lobes and shortly exserted stamens. It is also morphologically similar to Ruellia exserta, but differs by its habit, a shrub (not liana), inflorescence, thyrsus with opposite dichasia (not secundiflorous thyrsus) and short exserted stamens (not long exserted), and to Ruellia beckii differing by its habit, a shrub (not liana) end calyx lobes oblong-lanceolate with acute apex (not oblanceolate to obovate with retuse to obtuse apex). We provide a detailed description, illustrations, comments, data on distribution and habitat and conservation status of the species.

Oberonia integrilabris (Orchidaceae), a new species from Yunnan, China, is described and illustrated. The species is most similar to O. jhae and O. segawae, but differs from O. jhae by its leaf basal joint, oblong petals with irregularly toothed margin and obtuse apex and is distinguished from O. segawae by its petals with irregularly toothed margin and obdeltoid lip with entire margin and acute apex. The conservation status of O. integrilabris is assessed as CR.

A new species of Sciaphila (Triuridaceae), S. kozushimensis Suetsugu, is described from Kozu Island, Izu Islands, Japan. The new species is similar to S. tosaensis in having unisexual flowers (the female towards the base of the rachis), perianth-segments without any appendages and club-shaped style that is as long as or slightly exceeds ovary in the flowering stage. However, it is distinguishable by smaller male flowers, wide and acuminate male perianth segments and somewhat dissimilar perianth segments. An illustration and molecular analysis based on ITS sequences of the new species are provided. A key to the Japanese Sciaphila is also provided for identification of these rare mycoheterotrophic plants.

Begonia fimbritepala (Begoniaceae) a new endemic species to the Atlantic Coastal Forest of Brazil is described and illustrated. This species resembles B. olsoniae in occupying the same habitat (rocky slopes and outcrops), and in the shape of the leaf blades and size of male flowers. It differs by glabrous leaves on the adaxial surface, villous abaxial veins with simple trichomes (vs. hispid on both surfaces, squamulose on abaxial veins with fimbriate scales) and tepals with ciliate margins (vs entire to slightly crenulate).

Begonia pulchrifolia D.K.Tian & C.H.Li, a new species in Begonia sect. Platycentrum A.DC. (Begoniaceae) from Sichuan of China, is described and illustrated. Morphologically, it is only similar to the young or smaller individuals of B. dielsiana and B. emeiensis in plant shape and some leaf characters but differs easily by its foliage color and deeper divided leaf lobes, small-sized flowers, hairy outer petals of the male flowers, and long abaxially winged fruits. Molecular phylogenetic analysis based on nrDNA also supported the distinction of B. pulchrifolia from B. dielsiana and B. emeiensis.

During fieldwork to investigate bryophyte communities in disjunct areas of savannas in the Eastern Amazon, a new species of Cheilolejeunea was collected. The genus contains species mainly inhabiting tropical rain forests, which also occur in seasonal forests or xeromorphic forests, such as Cheilolejeunea adnata, Cheilolejeunea discoidea, and Cheilolejeunea rigidula. The aim of this paper is to describe and illustrate the new species, as well as to present comments on its morphology, taxonomy and distribution. The new species is characterized by profusely branched, creeping plants with leaves widely spreading to squarrose, imbricate, suborbicular to obovate with usually incurved, rounded to obtuse apex and mammillose leaf cells, often with a lenticular papilla on the dorsal surface. Further diagnostic characters, as well as comments on its distribution and similarities with related species, are given.
