110 CLASSIFICATION ACCORDING TO [CH. 
Any resemblances to forms of Azra are at once nullified by the 
absence of true awns in Keleria. Festuca and Poa have more 
numerous flowers in the spikelet. Azthoxanthum has only one flower, 
with two stamens, in the spikelets. P/lewm and Alopecurus present 
resemblances, but see pp. 101 and 102. 
(b) Panicle elongated and lax—i.. all or most of the 
spikelets on distinct slender stalks, longer than 
themselves. 
(1) Panicle close: the spikelets on distinct and 
even long stalks, but the latter erect and keeping 
the spikelets near the main aais. 
In some cases the stalks from the main axis bear only one 
spikelet each and the type of inflorescence is that of a raceme ; 
usually, however, one or more of the lowermost stalks branch and 
disclose the panicle. 
* Panicle with few simple branches, racemous, 
each spikelet large and containing about four 
flowers, palea three-toothed at the apex. A 
small heath-grass, with hairs at the ligule. 
Triodia decumbens, Beauv. 
The inflorescence may have some resemblance to Melica (see 
p- 105), but the four-flowered spikelet, ligule, habitat and stature 
distinguish it at once. 
** Panicle with divided branches, which are more 
or less erect. 
+ Spikelets awnless. 
© Spikelets small, purplish, with two or at 
most three florets ; the upper on a stalk. 
Coarse moor-grass. 
Molinia cerulea, Mcench. 
©© Spikelets with six or more florets.
