Grasses, t. 22. 
NortH anp SourH Isuanps: Damp subalpine localities, not uncommon. 
Hardly more than a luxuriant state of the type. 
Var. semiglabra, Hack. MS.—F lowering glume glabrous on the back, its 
callus sparingly pilose. Otherwise as in the type. 
NortH AND SoutH IsnuAnps: Not uncommon. 
Var. humilior, Hack. MS.—Root often perennial. Culms 3-10in. high. 
Panicle very broad and spreading; branches few, distant, binate, few-flowered. 
—A. striata, Col. in Trans. N.Z. Inst. xxi. (1889) 107. 
NortH AND SoutH IsuANps: Probably not uncommon in mountain districts, 
Lake Waikaremoana, Hill! Clarence Valley, Lake Tennyson, Broken River. 
Tasman Valley, &c., T. #. C.; Lake Te Anau, Petrie ! 
Var. littoralis, Hack. MS.—Root annual. Culms 2-9in., often forming a 
compact sward. Panicle rather narrow, contracted, many-flowered. Empty 
glumes linear-lanceolate, narrower than in the type. 
Kermapec Isnanps, NortH AND SoutH IsuANDsS: Rocky or gravelly places 
near the sea, not uncommon. 
Var. Lyallii, Hack. MS.—-Culms 6-12in. leaves narrow, involute. 
Panicle Jax; branches few, binate or ternate. Spikelets larger, 1-4in. long. 
Flowering glume densely clothed with silky hairs.—A. Lyallii, Hook. f. Fl. Nov. 
Zel. 1. 297. 
Sour Isuanp: Near Westport, Townson! Okarito, 4. Hamilton! Jack- 
son’s Bay, Kirk ! Milford Sound, Lyall, Kirk ! Catlin’s River, Petrie! AuckK- 
LAND IsuaAnps: Kirk! 
Var. micrathera, Hack. MS.—Habit of var. Lyallii, but larger and leaves 
broader. Spikelets still larger, 1}in. long. Empty glumes linear-lanceolate, 
acuminate. Flowering glume short, 4 as long as the empty glumes, very thin, 
sparingly silky; awn from above the middle, short, delicate, hardly exserted 
beyond the empty glumes. 
ANTIPODES IsLAND, CAMPBELL IsLAND: Kirk! Possibly the same as 
Agrostis lentostachya, Hook. f. Fl. Antarct. i. 94; but I have not seen an au- 
thenticated specimen, and it is described as having no palea and a long awn. 
D. Forstert is one of the most generally diffused plants in New Zealand, 
and is certainly one of the most variable. In attempting to characterize its 
chief forms, I have mainly followed the grouping suggested to me by Professor 
Hackel, who has kindly examined sets of all the varieties contained in my her- 
barium. The species is as plentiful in Australia and Tasmania as in New 
Zealand. 
2. D. Billardieri, Kunth, Rev. Gram. i. 77.—Culms tufted, 
usually rather stout, erect or decumbent at the base, 9-18 in. high, 
leafy throughout. Leaves shorter than the culms; +-4in. broad, 
flat, striate, usually scabrid on the margins and veins; sheaths 
rather narrow, rough, the uppermost very long, usually enclosing 
the culm up to the base of the panicle; ligules long, membranous, 
lacerate. Panicle 4-12in. long, very broad and lax, often as broad 
as long when fully expanded ; branches numerous, in regular whorls, 
long, capillary, scabrid, trichotomously divided ; pedicels thickened
