10 



than 0.5 m. high, with rootstock, slender culms, and lanceolate leaves, the short 

 stalks of which are articulate with the sheath. Panicle few-flowered, terminal. 



Species one (M. barbinodis Franch. ). In the Congo region. 



After Phyllostachys add : 



Fargesia Franch. This genns differs from Phyllostachys, of which it will be 

 much better classed as a section, principally on accoimt of the sessile (in 

 PliyUostachys jiedicellate) fruit-nodes, and ?> styles separated to the base (in 

 PliyUostuchys being grown together for quite a distance). 



Species one {F. spathacea Franch.), in China. 



Under Bambusa Schreb. insert Arundarbor Rumph. as a synonym. 



To Bambusa probably belongs a form first described by Gamble as a new 

 genus Microcalamus (non Franch., whose name is older), then referred to 

 Arundinaria (as A. prainii). Habit of Arundinaria, but with 6 anthers. Seems 

 to be closely related to Bambusa senanensis Franch. 



Sect. III. GuadneUa Franch. (As a genus) according to Franchet's more 

 recent and complete statements must be restored to generic rank. 



Before Atractocaipa Franchet insert: 



Thyrostachys Gamble. Spikelets two-flowered, aiTanged in twos or threes 

 along the panicle-branches, subtended by large bracts. Empty glumes 2 ; 

 flowering glumes broad, many-nerved. Palea of the lower flower 3-keeled, 

 2-cleft almost to the middle, with subulate divisions, those of the upper flow- 

 ers romided on the back, slightly or not at all cleft. Lodicules 2 ; stamens 6, 

 free. Ovary on short pedicel, depressed turbinate. Style long, with 3 plimiose 

 stigmas. 



Species two, in Burniah. 



Oreobambos K. Schum. Spikelets two-flowered, arranged in many-flowered 

 whorls, subtended by 2 broad bracts; empty glumes 1-2; flowering glumes 

 broad, many-nerved. Palea generally two keeled, rarely rounded on the back. 

 Lodicules wanting. Stamens 6, free. Ovary on a short, naked gynophore. 

 3-cornered-ovate, smooth, produced or attenuated into a long, hairy, undivided 

 style with simple (V) stigma. 



Species one (O. Biichicaldii K. Schum.) in Usambara. 



Before Subtribe C. Dendroealameoi add: Bonia Balansa, a doubtful genus of 

 the Eubambusece, is characterized as follows : Spikelets 3-4, sessile on the panicle- 

 branches, 3-4-flowered ; the empty glumes separated from the nearest flowering 

 glumes by a naked internode 1 cm. long, which they surround like a sheath ; 

 lowest flower articulate with this internode. Flowering glumes 7-nerved. 

 Palea 2-keeled. Lodicules 3. Stamens 3. Styles 3, grown together to the mid- 

 dle. Stigmas plumose, elongated. Caryopsis cylindrical. 



Species one {B. tonkinensis Bal.) in Tonkin. The genus is very closely related 

 to Bambusa; the significance of the two lowest bracts (called empty glumes 

 by Balansa) is doubtful.
