XIV SYNOPSIS OF GEKEEA. 



clustered, on one side of the rachis. Glumes 4, the 



two lower empty ones awned. 



Oplismenus, p. 13. 

 Spikelets in a dense cylindrical spike or narrow thyrsus ? 

 furnished with stiff persistent bristles (sterile branch- 

 lets) on the pedicels below the joint. (Kangni, &c). 



*- Setaeia, p. 14. 

 ## Inflorescence spicate. Pedicels jointed below a bristly or 

 scaly involucre which encloses 1 — 3 spikelets. 



Involucre double, the outer whorl composed of stiff 

 bristles, the inner of hard scales connate at the base. 



Cencheus, p. 15. 

 Involucre composed of weak simple or feathery bristles. 

 (Dh&man or anjan, bajra, &c). (Vide Plate A., Fig. 5). 



Pennisetum, p. 16. 

 TRIBE II. Maydese. — Spikelets unisexual, Male florets in 

 terminal spikes. Female florets in spikes at the lower nodes, 

 or in a separate inflorescence, ultimately breaking up at the 

 jointed nodes (except in Zed). 



* Spikes with the male spikelets attached to the upper nodes, 

 and the female spikelets solitary or in pairs at the base 

 of the spike. 

 Spikes stalked, female spikelets 1 — 2 at the base of 

 the spike. Bract, sheathing, ultimately enclosing the 

 grain and becoming globose and stone-like. Tall peren- 

 nial grasses, usually growing in or near water. (Vide 



Plate A., Fig. 6). 



Coix, p. 18. 



Spikes projecting from a sheathing bract. Female spike- 

 lets 1-flowered, at the base of the spike. Outer empty 

 glume globose or ovoid, thick and stony, enclosing 

 the spikelet. Habit similar to that of Coix. 



Chionachke, p. 19. 

 ** Male spikes many, in a terminal panicle ; female axillary 

 and sessile. 



Female spikes fasciculate within the sheaths of the 

 leaves, each spike partially enclosed within a large 

 bract. Spikelets in a single row. A tall succulent 

 annual introduced from Mexico. (Teosinte). 



Euchl^na, p. 19. 

 Female spikes axillary, very large, and enveloped in leafy
