NortH AND SoutH Istanps: Damp subalpine localities, not uncommon. Hardly 
more than a luxuriant state of the type. 
Var. semiglabra Hack. MS.—Flowering glume glabrous. on the back, its callus 
sparingly pilose. Otherwise as in the type. 
NortH AND Souts Isrianps: 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 SovutH Istanps: Probably not uncommon in mountain districts, 
Lake Waikaremoana, Hill/ Clarence Valley, Lake Tennyson, Broken River, Tas-

Var. littoralis Hack. MS.—Root annual. Culms 2-9in., often forming a com- 
pact sward. Panicle rather narrow, contracted, many-flowered. Empty glumes linear- 
lanceolate, narrower than in the type. 
KermMapec Istanps, NortH AND SoutH Istanps: Rocky or gravelly places 
near the sea, not uncommon. 
Var. Lyallii Hack. MS.—Culms 6-12in. Leaves narrow, involute. Panicle lax; 
branches few, binate or ternate. Spikelets larger, 34-3 in. long. Flowering glume 
densely clothed with silky hairs.—A. Lyallii Hook. f. Fl. Nov. Zel. i (1853) 297.

Var. micrathera Hack. MS.— Habit of var. Lyalli, but larger and leaves 
broader. Spikelets still larger, 41-1 in. long. Empty glumes linear-lanceolate, acumi- 
nate. Flowering glume short, $4 as long as the empty glumes, very thin, sparingly 
UES. awn from above the middle, short, delicate, hardly exserted beyond the empty 
glumes. 
ANTIPODES ISLAND, CAMPBELL ISLAND: 7’. Kirk! Possibly the same as Agrostis 
leptostachya Hook. f. Fl. Antarct. i (1844) 94, but I have not seen an authenticated 
specimen, and it is described as having no palea and a long awn.
