208 THE TRUE GRASSES. 



section is only 60 cm. high, herbaceous, producing 

 merely two large leaves on each culm. 



Species one (G. marantifolia Franch.), grows at 

 Gaboon in tropical West Africa. 



Fossil Species. — A plant from the middle Pliocene of 

 South France is placed in this genus as B. lugduuensis 

 Sap., and perhaps correctly. On the contrary, the 

 species described under Bambusa of different authors 

 are, according to Schenk's critical remarks, partly re- 

 mains of Arundo and partly fragments of other species 

 which cannot be classified. (Engler.) 



300. Atractocarpa Franchet. Spikelets in loose, ter- 

 minal racemes, very much laterally compressed ; two 

 empty glumes, then several $ or sterile flowers, finally 

 a ? , terminal flower. Branches of the style conical at 

 time of fruiting, broader than the caryopsis. 



Species one (A. olyrceformis Franch.), on the Congo 

 at Brazzaville. According to Franchet this grass grows 

 only 30 cm. high, is herbaceous, and has ovate-lanceo- 

 late leaves 18 cm. long by 7-8 cm. broad. 



301. (^287) Gigantochloa Kurz. Differing from Bam- 

 busa only by its monadelphous stamens. Tall arbores- 

 cent species with numerous, dense fascicles of spikelets 

 in branched panicles. 



Species 4-5, in the Malayan Peninsula and Archi- 

 pelago. G. verticiUata Munro grows to the height of 

 40 m., with the branches beginning very high wp on the 

 stem. 



302. (288) Oxytenanthera Munro. Spikelets long, 

 conical, in compact fascicles, with £ terminal flowers, 

 and 1-3 $ or sterile ones below ; empty glumes 4-7, 

 acute ; lodicules none ; anthers ending in a bristle or 

 several hairs ; fruit as in Bambusa. Tall shrubs. Five 

 typical species in the East Indies and upon the Sunda 

 Islands ; a sixth, forming the section Scirpobambos, with 

 large, spiny, capitate inflorescence (0. Abyssinica Munro), 

 abounds everywhere in tropical Africa. 



303. Puelia Franchet. Spikelets in short, terminal 

 panicles, otherwise as in Atractocarpa, but with the
