Gluma mutic ; flosculis 3, sessilibus, distiche imbricatis, 2 inferioribus neutris, 1-paleatis; terminali 
hermaphrodito, 2-paleato. Palee fl. inf. carinate, aristatee; fl. term. palea inferiore carinata, mutica ; 
superiore lineari. Sguamule 2-lobe. Stamina 2-6. Ovarium sessile.—Gramina planifolia; spiculis 
paniculatis, pedicellatis. 
A small genus of Australian, South African, and New Zealand Grasses, with short or long and branching culms, 
flat or concave (not involute) leaves, and panicled spikelets.—Glumes two, unequal, keeled, hardly awned, shorter 
than the florets. Florets three, compressed; two lower of one acuminate, keeled palea, containing neither stamens 
nor pistil; upper (or terminal) flower hermaphrodite, and of two pales; lower palee compressed, very blunt ; 
upper linear. (Named in honour of F. Ehrhart, a Swiss botanist.)

Haz. Northern Island. Tufts at the top of the Ruahine range, Colenso. 
A small, tufted, glabrous Grass, 4 inches to a span high, all my specimens of which have dried of a very pale 
straw-colour.—Culms much branched; branches covered with suberect distichous leaves, 2—4 inches long, which are 
linear-subulate, faintly nerved, concave, 1 inch broad at the base, and suddenly contracted at the ligula, which is 
very short and ragged, smooth or rather scabrid above, quite smooth on the back. Panicle 14-2 inches long, 
inclined, of few, slender, suberect branches or one-flowered pedicels. Spikelets compressed, linear-oblong, + inch 
long, deeply striate or nerved. Glumes acuminate, unequal, half as long as the awned palee of the lower florets, 
which are twice as long as the blunt lower palea of the upper (hermaphrodite) floret. Lower florets with long silky 
* I have received very great assistance in the determination of the Grasses from my friend Major W. Munro 
(39th Regiment), who has made the whole Natural Order his special study, and possesses an unrivalled knowledge 
of the genera and species. Most of those here described have been critically examined by both of us, and our views 
of the limits of the genera and species are quite in accord.
