BOTANY OF KERGUELEN ISLAND. 
19. Poa Cookii, Sook.f.; Fl. Aniarct. 382, t. 139 (Festuca), 
Forma 1. ; foliis culmum superantibiis, panicula elongata interrupta. 
Forma 2. ; foliis culmum superantibus v. mquantibus acuminatis pungentibus, 
panicula densa sub-cylindracea. 
Forma 3. ; foliis cmlmum sequantibus subacutis v. obtusis, 2 >anicula minore 
la.viore, spiculis paucifloris coloratis. 
Abundant and ascending to a considerable height : — Forma 1. Christmas Har- 
bour ; Forma 3. E-oyal Sound, on a high hill, Eaton. (Marion and Heard Islands, 
Moseley ) . 
This fine grass should, unquestionably, he referred to Poa (as now defined by the 
compressed flowering glume, &c.), along with its near congener Eactylis ccespitoso * 
of Fuegia and the Falklands, from which it dilTers, amongst other characters, in never 
forming tussocks. It is scarcely specifically distinct from P. foUosa, Hook, f . Hand- 
book of N. Z. Flora 338 (Festuca foliosa, FL Aniarct. i. 99, t. 55 ; Fl. Nov. Zeald. 
i. 308) ; and this, again, from the Fuegian Poa lanigera, Nees (Festuca fuegiana, Fl. 
Antarct. 380). The flowering glumes are often obscurely, or not at all toothed. The 
spikelets are 3-5-flowcred and in. long (not eight lines as misprinted for three 
lines in the Antarctic Flora). A. Gray remarks of Kidder’s specimens that they 
seem to be male only. 
Poa pi'atensis, L. 
Introduced by sealers. 
Poa annua, L. 
Introduced by scalers. 
20. Festuca erecta, E' Erv. 
Common and ascending to a considerable elevation. (Fuegia and the Falkland 
Islands.) 
Often forming tussocks ; jianicles green or purplish. 
21. Festuca kerguelensis, Eook. f. Triodia kerguelensis, Fl. Antarct. 
379, t. 138 {Poa). 
Common and ascending to 2,000 feet. 
Spikelets sometimes 1-flowcrcd. A very variable grass in stature, evidently 
allied to F. erecta, and more nearly still to F. scoparia (Fl. Antarct. 98 ; Fl. Kov. 
Zeald. i. 308), of which possibly it is a dwarf form, as suggested in the Handbook 
of the New Zealand Flora, p. 341. The naked base of the flowering glume, however, 
will always distinguish all the specimens I have examined. 
Filices. 
1. Cystopteris fragilis, Bernh. 
Crevices of rocks near the hill-tops, Eoyal Sound, Kidder, Eaton. (Fuegia, 
Falklands, and N. and S. temperate regions generally.) 
* The name Voa ctespitosa being occupied by Forster, tbough it is doubtful to -wliat species it applies, I 
propose that o'ljiabdlata for the Tussock grass, 'n hich is the Festuca fhibelkita, Lamk.
