Stems long or short. Leaves more rigid, with narrower leaf-lobes than in C. hetero- 
carpa, their bases much spread. Unripe achenes with a very wide, delicately mem- 
branous wing. I think C. poecilophylla, C. Koch, must be intended for a var. of 
this plant. 
II. PLerocynz. (Sp. 17). 
17, C. anthemoides (Linn. Sp. 1256); variably pilose or hirsute, 
diffusely much branched ; leaves half-clasping and often toothed at 
base, sub-bipinnatifid, the lower lobes short, simple or toothed, the 
upper longer, inciso-dentate or pinnulate, the lobes and lobules broadly 
linear, nerved, acute; pedune. lateral or terminal, shorter or longer, 
filiform ; iny.-scales numerous, narrow-oblong, obtuse, glabrous, with 
hyaline or white edges; ray-fl. in many rows, their achenes winged, 
with minutely granulated or smooth faces. DC. 1. c. 79. Lam. Ill. t.

leaves opposite, clasping at base, pinnati-partite above the middle, 
sparsely pilose or glabrous, lobes linear, thickish, entire, callous-tipped ;

A very curious and distinctly marked species, which might almost be made the 
type of a genus, in some measure connecting Cotula with Otochlamys. The structure 
of the achene is very curious, reminding one in some degree of that of an Arctotts. 
Viewed on its dorsal side, it shows merely the flat, wing-edged, oblong, disc-like 
form of an ordinary achene in Cotula, but viewed in front, it presents, within the 
marginal wing, the aspect as of a grain of wheat, with a slit more or less open down 
the middle: this is formed by two intra-marginal, longitudinal, inrolled wings. 
The marginal flowers, though formed like the rest, are generally abortive, on longer
