Perrm.—On a Variety of Celmisia sessiliflora. 859 
Spikelets usually 6-8, lower distant on slender peduncles, upper approxi- 
mate and nearly sessile; all short and pale-brown ; uppermost male, others 
male at the base only ; bracts very long and slender. 
Glumes shorter than the utricles, broad, very membranous, pale-brown 
at sides, white near the three-nerved midrib which is continued beyond the 
bifid apex into a long usually scabrid awn. 
Utricle turgid, plano-convex, pale-brown, beak short, bifid, toothed or plain. 
Arms of the style 8. ^ 
Hab. Maniototo Plain 1,000-2,000 feet ; Nevis Valley 1,500 feet. 
Named in honour of T. F. Cheeseman, Esq., Curator of the Auckland 
Museum, who has done much to settle the New Zealand species of this 
genus. 
Art. XLV.— Description of a Variety of Celmisia sessiliflora, Hook. f. 
By D. Perrm, M.A. 
[Read before the Otago Institute, 30th January, 1883.] 
Celmisia sessiliflora var. minor. 
Mvocn smaller in all its parts than the typical form of the species. Stems with 
leaves on about as stout as a goose quill, longer and much more branched. 
Leaves 4 of an inch long or less, 44; wide; sheaths longer and broader than 
the leaves, and much more villous than the type, especially at the tops of the 
sheaths. Achene relatively very short, about 4 the length of the pappus. 
This well-marked variety differs from the type of the species most con- 
spicuously in the greatly smaller size of all its parts, and in the greater 
length and subdivision of its branches. Though separated from the specific 
type by a wide interval, the differences are not of sufficient variety to justify 
giving it specific rank. If, however, it should be found in other distant 
localities, I should have no doubt about regarding it as a distinct species. 
I have never gathered or seen any forms sensibly intermediate between this 
variety and the common form of the species. The genus is one that 
abounds in variable species, and the systematic working out of the varieties 
is much needed. 
Hab. Swampy ground on the summit of Maungatua, Taieri: 2,900 
feet.
