1^-2^ poll, longis, nodis prominentibus. 



tcrni 



nodosi, basi bracteis membranaceis, ramis ipsis (foliis except is) longioribus, bracteati, a/tic ]-fo/iati, 

 "rarius pauciramulosi, paucifoliati." Folia oblonga vcl ovato-lanccolata, 2-4 poll, longa, 5-1

vix 11 lin. longe, apice truncate, ciliate, ligula fere obsoleta. " Species singularis," " pecn- 



simse 



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 £ aninch 

 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 Fhyllostachys or a closely allied 



genus 



IV. Arthrostylidioi 



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



Spicule sursum deorsumque imperfecta, sepe cylindrical, multiflone, pedicellate vel sessilcs, distantcs vcl 



approximate, in racemos simphces vel panicidatos dispositse, rhachille articulis semper comparative 

 longis, flosculis sepe cito articulatim secedentibus . Floscuh 1-2 inferior** 1-paleacci, neutri, 

 sequences perfect!, terminales 1-2-3 tabescentes. Gluma 2 breves vel brevissime. Pale* inf. ri ores 

 sepe acuminate. Squamul* 3 fimbriate, obtuse vel acuminate. Stamina 3. Sty It 2, basi plerumque 

 conspicue discreti (laterales fide Grisebach), stigmatibus pilosis vel phimosis. Ovarium glabram, 



oblongum. 

 Gramina America3 equinoctialis et insularum India3 occidentalis incole, arborescentia vel suflruteosa, 



foliis latis vel angustis vel minimis, foliorum costa inferne tantum conspicua, ncrvis secundaria 

 subobsoletis, venulis transversis nullis. 



This oenus 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 Armdimria ; 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 " Triglossse," except Anlonemia Goudot, which is scarcely to be distinguished except 

 by its peculiar habit and long loose spreading diffuse panicle. 





Conspectus Specierum. 



Sect. I. Panicula decomposita, spicis pluribus fasciculatis. 



Vagina fimbriate. Spicule conformes \. A. Hmikei
