A New Species

A new species of Bertolonia (Melastomataceae; Bertolonieae) endemic to the Brazilian Atlantic Forest is described and illustrated. Bertolonia organensis is known from only one locality in the Serra dos Órgãos National Park, state of Rio de Janeiro. The main diagnostic characteristics that distinguish B. organensis are the leaves with bullate adaxial surface and foveolate abaxial surface, cordate base and seven acrodromous veins, petiole and hypanthium glandulose-punctate, setulose and setulose-glandulose, the external calyx lobes erect, thick, narrow-triangular, apex acuminate-glandulose, margin entire, not ciliate, and the anthers connective dorsally appendaged, trilobed or with an acute calcar. Comparisons with similar species, geographic distribution and habitat are presented for the new species, as well as a key to identify all Bertolonia taxa known from the state of Rio de Janeiro. Bertolonia organensis is classified as Critically Endangered (CR).

Dryopteris lijianxiuii X. J. Li, a new species of Dryopteris Adans. from Shandong, China, is described and illustrated. It is closer to D. lacera (Thunb.) O. Kuntze for its morphological and palynological characters of LM and SEM studies but differs by a number of characters, such as, the leaves rectangular roundlanceolate, apex acuminate, and without narrow sharply; sori ornamented in the upper or middle part of 1-3 pairs of pinnaes at the base of the leaf, and densely covered with the upper and middle pinnaes back; spore perispore with tuberculiform-rugulate protrusions, and surfaces with melting ice and snow ornamentation. The sp. nov. is described with LM and SEM characters of spore and fronds, compared with that of D. lacera (Thunb.) O. Kuntze and provided with photographs. Bangladesh J.

A New Species

Moldenhawera is a small genus of Caesalpinioideae (Leguminosae), characterized by biramous (T-shaped) trichomes, compoundly pinnate stipules, hypanthium absence, clawed petals, dimorphic androecium, and anther connective of the fertile stamen pubescent. Moldenhawera congestiflora, a new species from the Atlantic Forest in Bahia State, Brazil is described and illustrated. It is distinguished from other species of the M. sect. Brasilianae by the combination of its tree habit, leaves relatively long (rachis > 24 cm long), leaflets elliptic to oblong with apex acuminate, flower buds densely grouped at the inflorescence apex, flowers pentamerous, petal blades relatively small (6–8 × 4–5 mm), and base of fertile stamen villous. Additionally we provide a new identification key for the section Brasilianae.

SummaryThilachium madagascariense Fici, a small tree characterised by 1-foliolate leaves with articulate petioles, leaf blades elliptic or narrowly obovate with base attenuate and apex acuminate, flowers in groups of 2 – 3 at the top of lateral twigs and a high number of stamens, is described and illustrated from forest habitats of eastern Madagascar. The new species is similar to T. laurifolium Baker, a species endemic to central and eastern Madagascar, differing in the longer leaves with acuminate apex, flowers conferted at the top of lateral twigs, shorter pedicels, higher number of stamens and shorter gynophore. Its affinities are discussed and an updated key is provided for all the species of the genus Thilachium.

It is similar to A. obconica C.R.Lin & Yan Liu with the perianth obconical campanulate, stamens inserted at upper third of perianth tube, but it can be clearly distinguished by leaf blade narrower and longer, perigone lobes longer (6–8 mm), adaxial densely papillose and scabrous, apex acuminate and outcurved, and stigma upper surface slightly concave. This new species is only known from Luocheng Mulao Autonomous County in Guangxi, China.

Primulina lechangensis (Gesneriaceae), a new species from northern Guangdong province in southern China is described and illustrated. Its morphology suggests affinities to P. longicalyx, but can be distinguished from similar taxon by several distinct characters including: smaller leaf blade (2.0-3.5 × 1.0-1.2 cm), base cuneate-attenuate; smaller bracts (1.0-1.5 × c. 0.15 cm); shorter calyx lobes (0.8-0.9 cm long) tuberculate inside; smaller corolla tube (c. 2 cm long), inflated in the middle and contracted near the mouth; shorter glabrous filaments (0.3-0.4 cm long), inserted 1.3-1.5 cm from base of corolla; stamens and staminodes glabrous; pistil 1.4-1.5 cm long, and capsule c. 1.5 cm long. This species is further exemplified by photographs, and a distribution map is presented.DOI: http://dx.doi.org/10.3329/bjpt.v21i2.21359Bangladesh J. Plant Taxon. 21(2): 187-191, 2014 (December)

A new species of Gesneriaceace, Primulina yangchunensis, is described and illustrated from China. The species is related to P. orthandra, but it can be easily distinguished by its leaf blade base cuneate, margin entire and rugose, both surfaces hispid, longer bracts broadly lanceolate, 1–2 cm long, and the length of the abaxial lip obviously longer than that of the adaxial one. The conservation status of this new species was assessed as “Critically Endangered” (CR) according to IUCN Red List Category and Criteria.
