528 GBAMINEJE: 



covered almost to the summit with ventricose, acuminate sheaths : hence the determination 

 of the species requires coafirmatioa. Spike 2" long ; stamens 20-30. — Hab. S. Vincent !, 

 Guild, (perhaps introduced) ; [Brazil] . 



2. GVA'DVA,KiA.

 ones sterUe, several imperfect, Palea convex. Stamens 6. Sti/le %(-" 2 ")-partite. — Stem 

 arioreous ; apikelets usually clustered, often branched from the lowest glumes : internodes 

 of the rhachis broad. 



2. G. latifaUa, Kth. Spikelets clustered, long, acuminate, curved ; glumes striate- 

 somewhat shining, ciliate, superior gradually longer and tapering. — Humb. PI. Equin. t. 21' 

 — Bambusa, Humb. — Stem "24' high, nodding at the summit;" leaves "linear-oblong' 

 glabrous at the margin : sheaths with rigid bristles at the summit ;" spikelets 2"-3" long, 

 2i"' diam.— Hab. Trinidad!, Pd.; [Venezuela]. 



3*. BAMBUSA, Schreb. 



Spikelets laterally compressed, many-flowered : rhachis slender : glumes distichous, more 

 than 2 of the inferior ones sterile, many, or several imperfect. Palea convex, ciliate. 

 Stamens 6. Caryopsis lanceolate. — Stem arboreous or shrubby ; spikelets ■usually branched 

 from the lowest glumes, often clustered. 



3*. B. Tulgaris, Schrad. I branches striate; leaves oblong-linear or lanceolate- 

 acuminate, rounded at the base, scabrous at the margin and beneath : sheath striate to 

 the base; spikelets oblong-lanceolate, acuminate ; glumes ciliate, many-nerved, striate 

 chiefly above, superior oblong-lanceolate, abruptly passing into the inferior sterile ones, 

 several fertile; style long, pubescent, 3-2-fid or simple. — Kth. Revis. t. 73, 74. Rupr. 

 Sambus.f. VI. — B. Thouarsii, ^<A. B. arnndinacea, jiit. {non Roxb.) — Stem"20'-30' 

 high, unarmed ;" largest leaves I' long, 2" broad, those of the younger shoots 6" long, 6'"- 

 8'" broad ; spikelets densely-clustered-solitary, straw-coloured, 6"'-10"' long. — Hab. Natu- 

 ralized and cultivated in Jamaica!, M'Nab, S. Kitts !, Triuidad !, Pd., Cr., but no document 

 exists in our collections that any Bambusa is of American origin, as was believed of this 

 species by former authors ; [East Indies]. 



4*. B. Sieberi, Gr. Branches shining, not striate; leaves lanceolate-acuminate, 

 rounded at the base, slightly scabrous at the margin and beneath : sheath striate above, less 

 striate below; spikelets oblong-lauceolate, acumiuate; glumes ciliate, mauy-nerved, striate 

 near the summit, superior oblong-lanceolate, gradually passing into the inferior sterile ones, 

 several fertile ; style long, pubescent, 2-fid or simple. — B. arundiuaoea, Sieb. Mart. B. su- 

 rinamensis, Rtipr. Bamb.f. 49 ?— Perhaps a form of the preceding : the same occurs among 

 B. arundinaeea in J. D. Hooker's collection as a cultivated Bamboo of the East Indies, 

 leaves glaucescent, 6" long, 8'"-9"' broad ; spikelets usuaBy 2-3-partite, shining, straw- 

 coloured, 5"'-8"' long. — Hab. Naturalized and cultivated in Jamaica!, Al., Dist.; [Mexico!, 

 Guiana !, Brazil ! ; East Indie:s !] 



4. STREPTOGYNE, P. B. 



Spikelets cylindrical, 2-1 (-several) flowered, shortly pedicellate : rhachis produced be- 

 yond the flowers. Two inferior glumes sterile, unequal : the lowest interior, half as long as 

 the second. Flower exserted, cartilaginous-coriaceous : its glume convolute, awned : awn 

 terminal, straight. Palea enclosed, 2-dentate. Stamens " 3." Stigmas 3(-" 2 "), long 

 exserted, spirally twisted, persistent. Caryopsis linear, cylindrical, with a longitudinal fur- 

 row. Embryo minute. — A stout, smooth, herbaceous (or "woody") grass ; leaves very long, 

 linear ; spikelets distant in a long, straight, spiciform, raceme ; sterile glumes persistent at 

 fhe furrows of the puberulous axis ; cai-yopsis deciduous with the flower : several often 

 ^hering by their twisted stigmas.
