Agropyron enysii, n.s.
Culms erect, slender, sparingly leafy, 1ft.—2ft. high. Lower leaf-sheaths pubescent or sparingly villous, especially on the margins, upper glabrous, leaves flat; ligule very short, abruptly truncate, erose. Spike 3in.—5in. long, nodding, narrow, often interrupted below; spikelets scarcely ½in. long, usually 3-flowered, glumes slightly coriaceous and scabrid, outer glumes subequal, with scarious margins, very narrow, 5-nerved, the intermediate nerves obscure, abruptly narrowed into a stiff scabrid point or awn half the length of the glume, concave; flowering-glume one-third longer, 5-nerved, abruptly narrowed into a stout point one-third to a quarter the length of the glume; palea almost equalling the flowering-glume, retuse, hairy, the nerves strongly ciliate; ovary villous, styles very short; lodicules obovate – acute, glabrous. Asprella aristata, D. Petrie, in Trans. N.Z. Inst., xxvi. (1893), 272.
Hab. South Island: Slopes of Mount Torlesse and Broken River; J. D. Enys! (1877): Bealey Gorge; T. Kirk: 2,500ft. to 4,000ft., Southern Alps; N. T. Carrington! (1881).
Easily distinguished from any other New Zealand species by its narrow spikes and short spikelets. It greatly resembles large states of Asprella gracile, Benth. and Hook. f., in
general appearance, but is readily recognized by the pair of outer glumes, while the lodicules are not ciliated, nor are the styles naked below. The palea is almost coriaceous in fruiting specimens.
I am greatly pleased to attach the name of its original discoverer to this distinct species, if only to acknowledge the great service he has rendered to botanical science by investigating the flora of the Broken River basin and other places in the Southern Alps.
