4. P. KUMASACA, Munro. Culmo seniitereti, superne pallido, ramis dplco l-foliatis ; 

 ■vaginis brevissiniis, fere ohsoletis. — Bambusa kumasaca, Zoll. Herb. Steudel. /. c. 331 ; 

 Miq. Fl. Intl. Bat. iii. 419 ; Ann. /. c. 286. 



Hab. Jayioma., Siebold, Buerger \ Veitchl; ins. Kiusiu, Surasi (" Ko-sasa" incolis), Pierc//. In Java cult., 

 Zollinger, v.s. 



Culmus (pars superior sesquipedalis tantum adest) fere simplex, flexuosus, internodiis glabris, pallidis, 

 1^-2| poll, longis, nodis prominentibus. Rami i-l^-pollicares, temi.vel quaterni, fasciculati, 2-3- 

 nodosi, basi braeteis membranaceis, ramis ipsis (foliis exceptis) longioribus, bracteati, apice l-foliati, 

 "rarius pauciramulosi, paucifoliati." Folia oblonga vel ovato-lauceolata, 2-4 poll, longa, 5-10 

 lin. lata, spinoso-acuta, basi in petiolum, dorse earinatum, 3 liu. longum attemiata, marginibus 

 spinoso-serrata, supra glabra, subtus vix pallidiora, pubescentia vel demum glabresceutia, nervis secuu- 

 dariis utrinque 6-7 ; venulis transversis creberrimis, puuctulis minutis subasperatis. Vaginae brevis- 

 simse, vix 1| lin. longae, apice truncato, ciliatae, ligula fere obsoleta. " Species singularis," "pecu- 

 liaris certe formatiouis et vix dubie distinctum genus" (Steud.). 



This is certainly unlike any Bamboo I have seen. The branches in the specimens 

 which I have had access to, although divided into 3 internodes, do not exceed \ an inch 

 in length, and bear a single leaf at their extremity. However, from the general appear- 

 ance of the plant, I feel persuaded that it belongs to Fhyllostuchys or a closely allied 



IV. Arthrostylidium. 



Ruprecht, /. c. 117 ; Steudel, /. c. 335. 



Spicuke sursum deorsumque imperfectee, ssepe cylindricse, multiflorse, pedicellatae vel sessiles, distantes vel 

 approximatse, in racemos simplices vel paniculatos dispositae, rhacbillifi articulis semper comparative 

 longis, flosculis ssepe cito articulatim secedentibus. Flosculi 1-2 inferiores 1-paleacei, neutri, 

 sequentes perfecti, terminales 1-2-3 tabescentes. Glumce 2 breves vel brevissimse. Palea inferiores 

 ssepe acuminatse. Squamula 3 fimbriatse, obtusiE vel aeiuninatse. Stamina 3. Styli 2, basi plenunque 

 conspicue discreti (laterales fide Grisebach), stigmatibus pilosis vel plumosis. Ovarium glabrum, 

 oblougum. 



Gramina America aiquinoctialis et insularum Indiae occidentalis ineolae, arborescentia vel suffruticosa, 

 foliis latis vel angustis vel minimis, foKorum costa inferne tantum conspicua, nervis secundariis 

 subobsoletis, venulis transversis nullis. 



This genus, which derives its name from the peculiar readiness with which the perfect 

 flowers, except perhaps the lowest, fall off in the spicula, is not in that way to be distin- 

 guished from some species of AruncUnaria ; but the lower barren flower, with only 1 

 palea, keeps it well distinct from that genus. It does not approach any other genus of 

 the " Triglossge," except Aulonemia Goudot, which is scarcely to be distinguished except 

 by its peculiar habit and long loose spreading diffuse panicle.
