7. Deyeuxia glabra sp. nov. 



G-ramen D. Forsteri Kunth var. littoralis Hackel affine. 



Spiculae parvae, pallide virides, 3-3| mm. longae ; glumae floriferae 

 vacuis dimidio breviores, ovatae, apice + truncatae ac erosae, glaberrimae 

 membranaceae, hyalinae, leviter 3-nervatae, nervis lateralibus vix excur- 

 rentibus, nervo medio in aristam terminalem persubtilem rectam vel cur- 

 vatam raro extra glumam exsertam producto ; glumae basi glaberrima 

 rachilla brevi gracili parce pilosa. 



A slender laxly tufted grass, branching from the base. 



Culms up to 30 cm. high, very slender, sparingly leafy. Leaves distant 

 on the culms, the lower short, the upper longer ; sheaths long, the upper- 

 most reaching the base of the expanded panicle ; blades flat, linear, smooth 

 thin, striate, gradually tapering to the tip, bright green ; ligule long, mem- 

 branous, coarsely toothed or cut at the top. 



Panicle contracted in the young state, later lax and spreading, broadly 

 ovate, 10 cm. long or less ; branche in rather distant whorls of 4 or fewer, 

 finely capillary, scaberulous, once or twice trichotomously divided, naked 

 below, bearing few spikelets on long very delicate pedicels. 



Spikelets small, 3-3J mm. long, pale green ; empty glumes equal, lanceo- 

 late, acute, membranous, obscurely 1 -nerved, slightly ciliate on the upper 

 part of the keel, scarious at the sides and top ; flowering-glumes about half 

 as long as the empty, ovate, more or less truncate and erose at the tip, 

 perfectly glabrous, membranous and hyaline, faintly 3-nerved, the lateral 

 nerves barely excurrent, the median produced into a delicate straight or 

 bent terminal awn rarely exserted beyond the empty glumes, the base of 

 the glume destitute of hairs ; palea highly membranous, narrow, as long 

 as the flowering-glume, its nerves obscure and glabrous ; rhachilla short, 

 slender, sparingly pilose. 



Hob. — Moist grounds by the seaside at Bluff and Fortrose, Southland. 



This plant can be readily distinguished from D. Forsteri by the glabrous 

 flowering-glumes, the short delicate terminal awn, and the absence of a tuft 

 of hairs at the base of the flowering-glume.

8. Danthonia teretifolia sp. nov. 



Gramen D. ovatae Buchanan affine ; differt foliis gracilibus, firmis, 

 teretibus, pilis subrigidis appressis + dense vestitis, in apices elongatos 

 filiformes undulatos attenuatis ; paniculi ramis infimis 3-verticillatis ; 

 dentibus glumae floriferae lateralibus scariosis in aristas ciliatas gradatim 

 attenuatis ; et arista media subtus complanata ac contorta. 



A densely tufted grass, forming large compact yellowish-green tussocks. 



Culms 30-50 cm. long, exceeding the leaves, slender, terete, glabrous, 

 slightly grooved, yellowish, invested by 2 distant long-sheathing cauline 

 leaves not exceeding the panicle. 



Leaves few on each culm, slender, involute, terete, wiry, pale yellowish- 

 green, the sides and inner face densely pilose with stiff appressed hairs, 

 the margins thickened and glabrous, the keel rounded and polished and 

 sparingly pilose or almost glabrous, gradually narrowed into long filiform 

 wavy tips ; sheaths about A- as long as the blades, broad and closed almost 

 to the tops, coriaceous, striate, glabrous or nearly so, persistent ; ligule a 

 broad band of delicate hairs with longer tufts at the sides.
