 Accana huttoni. 

 Growing 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 apes; upper leaves becoming sessile 

 and exstipulate, from 9-18 inches high ; heads sub-globular, florets sessile 

 with a small scarious bract at the base of each, fimbriated on the margin ; 

 bracteola two, sub-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-augled, 

 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 Biver Ashburton, in
