It may perhaps be judged unnecessary to add another variety to the many 

 already known of this variable species, but the habit of this Alpine foi-m, 

 with its succulent roots and confluent tussocks, demands notice. 



Collected by J. Buchanan, at Dusky Bay, 1863. 



Accena glabra, Buchanan, n. sp. 



A prostrate, perfectly glabrous herb, branches ascending, leafy. Leaves 

 I inch long ; leaflets 3-4 pairs, coriaceous \ inch long, obovate or cuneate at 

 the base, deeply cut into 2-3 obtuse teeth on each side ; scapes 3 inches long, 

 leafy at the base, ynth often one small leaf near the middle ; heads large, 

 globose ; calyx much compressed, unarmed, 4 angled, 2 angles very small, the 

 other 2 much produced, wing-like ; petals 4, united at the base, persistent, 

 green, tipped with dark red ; bracteolse entire, or 3 cleft at the point, fimbriate 

 or lacerate on the margins ; stamens 2 ; filaments long ; stigma dilated 

 upwards, fimbriate or lacerate on both margins ; achene 1, pyriform, sus- 

 pended from the point. 



This very distinct species may easily be distingtiished by the regular 

 ascending branches, small coriaceous leaves and large capitulum of flowers, its 

 more exact specific distinctions will be found in the much compressed calyx, 

 the 2 lateral expansions, which are almost produced into wings, and the per- 

 fectly glabrous state of all its parts. 



Collected on the mountains near Lake Guyon, Nelson, at an altitude of 

 3,000 feet, by H. H. Travers, February, 1871.

Celmisia lateralis^ Buchanan, n. sp. 



A small prostrate, glandular, pubescent plant; rhizome creeping, covered 

 with appressed sheathing scales, branched. Branches ascending, ^ inch long, 

 densely covered with small sheathing leaves. Leaves rigid, erect, |— |^ inch 

 long, entire, linear, acuminate or obtuse, broader at the sheathing membranous 

 base, acerose, pungent, glabrous on both surfaces, or hispid on the backs of 

 young leaves ; margins glandular ciliate. Scapes 2-3 inches long, slender, 

 lateral, solitary or in pairs towards the ends of the main branches ; bracts 

 few ; linear siibulate, very narrow ; 2-3 alternate bracteate leaves at base of 

 scape j the whole glandular pubescent. Heads large for the size of the plant, 

 |^-| inch diameter involucral scales in 3 series, linear lanceolate, subulate ; 

 outer series glandular, inner series glandular and silky ; borders white, mem-
