secondly, in the male or imperfect or rudimentary flowers, when present, being above,, 
not below, the fertile one. The former character is all but universal; but from the 
latter one exceptions are not very rare, besides that, where there is only one flower 
without any cuiitiiiuaticm of the rhachilla beyond it, the character entirely fails. I 
should add that in some tribes of Poaoeic there are two or more perfect flowers in the 
spikelet, which is not the case in Panicacew.” 
Tribe 7. PHALiRiDEiE. — Flowers single, terminal, liermaplirodite. 
Glumes 6 (or 5 and palea), l-iierved or carinate. Fjxamples : 
MicroJeena slipotdes, the Meadow Fice-grass ; and ^halaris canariensisj 
the Canarj-grass. 
Tribe 8. AaROSTinE-E. — Spikelets with single llowers, rhachilla 
naked beyond the dower or prolonged into a bristle or stripes. 
8ubti’ibe 1. &tipe{S . — -Panicle loose or irregularly spiciform. 
Glumes, flowering usually terminated in an awn, fruiting closely 
investing the caryopsis (grain). Rhachilla not prolonged beyond 
the dower. Examples: Aristida, tlie Three-Awued Spear-grasses; 
and Biipa vertlcillata^ the Bamboo-grass so common, in mountain 
scrubs. 
Snbtribe 2. 'Phlmuhes , — Panicle spike-like, compact, cylindrical 
or subglobose. Glumes, dowering muticus or terminated by 1 to 3 
awns, fruiting loosely enclosing the grain. Khachilla sometimes pro- 
longed. Example: Echinopopon ovaius, the Eough-bearded grass. 
Subtribe 3. SporQhole<s . — Panicle loose or reduced to a raceme, 
very rarely Hjiiciform. Glumes, dowering muticus, Caryopsis (grain) 
somewhat denuded moi’c frequently than the open glumes. Hhacliilla 
not prolonged. Example: SporoMm, (See 'Mtat’s-tail grass,” the 
Jil-crow-beriy ” of the (Toucurry natives.) 
Subtribe 4. Euaprostece . — Panicle variable, more frequently 
loose. Glumes, flovrering frequently furnished with a dorsal awm, 
very rarely muticus. Caryopsis loosely enclosed in a glume. Rhachilla 
often prolonged. Example : Deyeuxia Forzier}^ a soft very light grass. 
Tribe 0. Avexeje.— S pikelets bearing 2 or more dowers, more 
usually paniculate. Glumes, liow'enng very frequently furnished with 
a dorsal awu or sometimes with a terminal one. Rhachilla more 
usually prolonged beyond the dowmrs. 
Subtribe 1. Airece . — Spikelets 2-do\vered, rhachilla not produced 
beyond the doAvers. Glumes, dowering muticus or rarely slender or 
shortly aristate. Examples : Eriachne^ several species met with in 
Tropii-al Queensland. 
Subtribe 2. Eiiavenece . — Spikelets 2 or numerous, rhachilla 
proiojiged more or less beyond the flowers. Glumes, flowering very 
often bearing a dorsal or terminal awn, geniculate or twisted. 
Example : Avena^ the Oat. 
Tribe 10. Ciij.obide^. — S pikelets with 1 or more flowers sessile 
along the rbaehis iu 2 series of unilateral or sexond spikes. Examples : 
Cliloris^ any of the Star grasses ; and Eleimne^ the Crab grass. 
Tribe 11. FESTrcK-i:. — Spikelets with two or more flowers 
variously paniculate or more rarely racemose. Glumes, flowering 
muticus or terminated in awns. 
Subtribe 1. Fappophorecd.—'Fowevhig glumes many-nerved, 
furnished with 3 or more aAAms, or 4-lobed without awns. Example: 
p€ippopJioru7n.
