Acana huttoni. 
Growine from a stout woody perennial rootstock. Leaves impari-pinnate ; 
radical 5-8 inches long; petioles long, slender, triquetrous, woolly ; sti- 
pules adnate, small, subulate, decurrent, expanding into a membranous, 
clasping base; leaflets spirate, or alternate, 11-17, enlarging upwards, the 
lower sub-rotund, the upper oval or obovate, all sub-plicate, incised, or 
inciso-dentate, midrib woolly on the under side, veinlets with a few hairs, 
the upper surface smooth. Peduncles erect, or inclined, sometimes decum- 
bent, angular, woolly, leafy to near the apex; upper leaves becoming sessile 
and exstipulate, from 9-18 inches high ; heads sub-globular, florets sessile 
with a small searious bract at the base of each, fimbriated on the margin ; 
bracteola two, sib-rotund: very concave, scarious, fimbriated on the margin, 
attached near the base of the calyx-tube on spirate angles, and in a young 
state wholly enclosing the flower. Calyx-tube elliptic in outline, 4-angled, 
the angles produced into wings, each face deeply wrinkled; calyx-lobes 
four. Corolla either absent or very fugacious. Stamens 2-8, immersed ; 
anthers oval, dehiscence introrse, filaments short, slender. Pistil—style 
erect, short; stigma dilated at the apex and fimbriated. Achenes two, 
plano-convex with an oblique ovoid outline, pale and long. 
Collected on the Canterbury Plains, near the River Ashburton, in
