03AC8790C2321D761EE18080EA25C162.taxon	materials_examined	Type species. Cochinchinochloa braiana H. N. Nguyen & V. T. Tran. Etymology. The generic epithet refers to the Cochinchine area (southern Vietnam, which includes Braian mountain, Lamdong Province where the species is located), and - chloa: grass. Densely tufted with rhizomes short-necked, pachymorph. Culms and branches scrambling or hanging over nearby vegetation or trees; culms of medium size, with relatively thin walls, nodes with a thick swollen patella. Branches several with the middle one dominant, elongating. Culm leaves usually purplish when young; the blade erect and inflated at the base, tardily deciduous; auricles present. Nodes of leafy branches with a thick swollen patella; leaf sheaths dense white cilia, auricles present. Inflorescence terminating leafy branches, indeterminate; each pseudospikelet subtended by a prophyllate bud and consisting of 1 – 3 transitional glumes, apex acute mucronate, margins shortly white-hispid, abaxial surface white cilia; two perfect florets; the rachilla internode between the perfect florets elongate; and a rachilla extension bearing an imperfect floret elongate at maturity; perfect floret consisting of lemma and palea; lemma oblong-lanceolate, shorter than the palea, apex acute, mucronate, convolute and uncovered palea, margins dense cilia; palea 2 - keeled with a narrow groove on the back, apex obtuse, margins dense cilia; lodicules 3, apex obtuse, dense ciliate; stamens 6, filaments free; glabrous ovary with long style; stigmas 3, plumose; caryopsis oblong with relatively thin pericarp. Note — This remarkable genus is distinctive based on the presence of a thick swollen patella at the culm nodes and nodes of leafy branches, pseudospikelets having two perfect florets, the rachilla internode between the perfect florets elongated, a rachilla extension bearing an imperfect floret at maturity, a narrowly 2 - keeled palea with an abaxial groove, three lodicules, six stamens, free filaments, a glabrous ovary with a long style and three stigmas, and an oblong caryopsis with relatively thin pericarp.	en	Nguyen, H.

03AC8790C2321D711EE1851FEAD4C455.taxon	etymology	Etymology. The specific epithet refers to the type locality, Braian mountain, Di Linh District, Lamdong Province, Vietnam. Culms and branches scrambling or hanging over nearby vegetation or trees, 8 – 15 m tall; internodes 60 – 80 cm long and 2 – 3.5 cm diam, when young sparsely covered with appressed white hairs; culm walls 2 – 3 mm thick; nodes with a thick swollen patella. Branches several with the middle one dominant, elongating. Culm leaves purplish green, when young covered with densely appressed white hairs on the abaxial surface; 20 – 23 cm long and 9 – 12 cm wide at the base, 6 – 8 cm wide at the top, the junction with the blade more or less horizontal, margins bearing dense white-brown hairs; blade tardily deciduous, erect, inflated at the base and base purple-brown, 20 – 25 by 12 – 15 cm, abaxial dense white hairs, margins densely ciliate at the base; auricle triangle shaped, 1.5 – 2.5 by 0.6 – 0.8 cm, margins bearing dense purple-brown bristles, c. 0.4 cm long; ligule very short, entire. Leafy branches 40 – 60 cm, nodes with a thick swollen patella, bearing 5 – 8 leaves; blades oblong-obovate, base broadly rounded, glabrous, 30 – 35 by 6.5 – 7.0 cm, veins in 10 – 12 pairs; sheaths bearing auricles c. 0.2 by c. 0.1 cm with dense bristles 4 – 6 mm long; inner ligule a low rim, c. 1 mm; pseudopetiole c. 0.2 by c. 0.2 mm. Inflorescences terminating leafy branches, indeterminate; pseudospikelets typically 2 – 3 cm when young and 4 – 5 cm at maturity, each subtended by a prophyllate bud and consisting of 1 – 3 transitional glumes, having two perfect florets and a vestigial terminal flower. Rachilla internode below the lower fertile floret does not elongate at maturity, c. 0.2 cm; rachilla internode between perfect floret elongate, c. 0.8 cm; and a rachilla extension bearing an imperfect floret at maturity, c. 1 cm. Perfect florets consisting of lemma and palea; lemmas oblong-lanceolate, 1.1 – 1.3 by 0.3 – 0.4 cm, veins 9 – 11, apex acute, mucro 1 – 2 mm long, shorter than the palea, margins bearing dense white cilia at the apex; palea 2 - keeled with a narrow groove on the back, 1.6 – 1.8 by 4 – 4.5 mm, the apex acuminate, mucro 1 – 2 mm long, margins bearing dense white cilia at the top; lodicules 3, obovate, 1.7 – 2 by c. 1 mm, margins ciliate; stamens 6, filaments free, 4 – 5 by 0.4 – 0.5 mm, apiculate with short tips; ovary glabrous with a long style and stigmas 3; caryopsis green when fresh, oblique, with a relatively thin pericarp, 1.2 – 1.5 cm long, protruding from the palea. Distribution & Habitat — This bamboo grows in the degraded natural forest in valleys, but is also common along rivers or valleys, between 1000 and 1200 m asl, southern Vietnam. Phenology — The plants were flowering between September and February. New shoots developed in June – August. Local uses — This species is of considerable importance to the local people. Its culms are used for making handicrafts and household tools.	en	Nguyen, H. N., Tran, V. T., Hoang, T. T.
