Tribe 1. Pantce^. — S pikelets hermaphrodite, more rarely by 
abortion unisexual, spicate or paniculate, rhacbis of the inflorescence 
not articulate. Glumes, flowering exaristate, fruiting indurated or at 
any rate more rigid than the exterior ones. Examples : Paspalum 
(see “Ditch Millet”), Panimm (see “ Summer* grass”), Cenchrus 
(see “ Scrub or Hillside Burr-grass ”). 
Tribe 2. Matde.e.— S pikelets unisexual, the terminal ones male, 
spicate or paniculate or (in Pariana, i\oi Australian) surrounding the 
female, lower ones female spicate, separating joint by joint with the 
internode of the rhachis (except in Zea). Examples : Goix (see 
“ Job’s Tears”) and Zea (the Maize). 
Tribe 3. Oryzej^. — S pikelets hermaphrodite or more rarely 
unisexual, paniculate or spicate ; rhachis of the inflorescence not 
articulate; glumes, the uppermost beneath the flower (palea ?), L-nerred 
or carinate. Examples: Orijza (see “ llice and the Eicc- 
grass. 
Tribe 4. Tristkgtnb-e. — S pikelets hermaplirodite, placed singly 
along the inarticulate branches of the panicle, or more rarely in pairs 
or fascicles, articulate with pedicel. Glumes, empty ariatate or 
muticus, floweriTig hyaline or fliiely membranous, terminated by a 
geniculate arista or muticus. Example : See At'uniUnella, a very 
common coarse grass met with on hillsides in Queeuslancl. 
Tribe 5. ZoYsiKiE. — Spikelets hermaphrodite or some imperfect, 
with inarticulate rhachis of the simple spike, which is furnished with 
joints conaistiug of a series, or fasciculate. Glumes, flowering, 
membranous, often smaller than the empty ones and hyaline. 
Subtribe 1. Anfliephorece . — Spikelets pedicellate, 3, or numerous 
crowded together in a deciduous fascicle. Glumes, the flowering 
sometimes a little longer than the empty ones, sometimes shorter and 
hyaline. Example : Tragus racemosus^ the small Burr-grass. 
Suhiribe 2. Euzogsiece . — Spikelets placed singly upon a pedicel, 
more rarely in pairs. Glumes, flowering shorter than tlie empty ones 
and hyaline. Examples : Perofis rara, the ('omet-grass ; and Zoysia 
pimyens, the Coast Couch-grass. 
Tribe G. AjinROPOOONEiE.- — Spikelets along the rhachis of the 
spike or branches of the panicle most often in pairs, or the terminal 
ones in triplets. tSpikelets in each pair homogaraous or heterogamoua. 
Glumes, flowering snialler than the empty ones, hyaline, often 
furnished with an awn. Examples: Imperata (see “ Blady Grass ”), 
Saccliarum (see “ ISugar-cane ”) ; Dimeria^ a grass resembling a 
Chloris common about Cairns; llemarthriay a common grass on 
swampy land ; Andropoyon (see the Blue Grass), and Aniliistirla (see 
“ Kangaroo-grass,” or the tall Oat-grass of the Darling Downs), 
Series B. POACEA5. 
Pedicel continuous below the glumes, llhachilla often articulate 
above the lower persistent glumes, continued beyond the fertile 
flowers, stipitiform or bearing either empty glumes or imperfect 
flowers, or sometimes there is a single terminal fertile flower as in the 
case of the Panicaceie, but separating joint by joint with its own 
glume from the empty persistent glumes. 
Mr. Benthani says: — “The main characters of Poaoeie consist, firstly, in the 
want of any articulation of the pedicel below the lower empty glumes, which remain 
persistent after the fruiting one has fallen away, or fall away separately ; and
