Key to the Genera 



We follow, where possible, the systematic arrangement given by Stapf in the 

 Flora of Tropical Africa. We add in brackets the reference to the genera 

 in our series. 



SUB-FAMILY I : Panicoideae.— Mature spikelets falling en- 

 tire from their pedicels or with them, all alike or 

 differing in sex and structure ; perfect spikelets 

 with two heteromorphous florets, the upper herma- 

 phrodite, the lower male or barren ; rhachilla not 

 continued beyond the upper floret (Genera 1-61). 

 TRIBE I : Mayde^e.— Sexes in different inflore- 

 scences on the same plant, or the female spikelets 

 at the base of the inflorescence, the male above 

 them ; spikelets never awned, the male and female 

 very dissimilar (Genera 1-4 J. 



1. Male and female spikelets in separate inflore- 



scences ; male spikelets in a large terminal 

 panicle ; the female spikelets in the axils 

 of the leaves. 



A. Female spikes distinct, articulated (vol. 32, 



15) .. ... ... ... 1. Euchlaena. 



B. Female spikelets grown together into a 



spongy more or less cylindrical body 



(vol/32, 15) ... ... ... 2. Zea. 



2. Male and female spikelets in separate portions 



of the same spike, the female below, 



A. Grain enclosed in the usually globose or 



ovoid ivory-like capsuliform supporting 



sheath (vol. 32, 17) ... ... 3. Coix. 



B. Grain enclosed in the hardened outer 



glumes (vol. 32, 17) ... ... 4. Polytoca. 



TRIBE II : Andropogone^e. — Spikelets usually in 

 pairs, one sessile, the other pedicelled, very rarely 

 both pedicelled, those of each pair alike as to sex 

 (homogamous) or different (heterogamous), rarely 

 3-nate or solitary on the axis of a usually spike-like 

 raceme. Involucral glume more or less rigid and 

 firmer than the floral glumes, the lower always
