ously pubescent or pilose ; leaves from a broad-toothed base, pinnatisect

no corolla) muriculated. Less. Syn.261. Cotula turbinata, Linn, Sp. 1258.

Very variable in size, (2-15 inches long, erect or procumbent) ramification and 
pubescence, also in the leaves, which are 1-3 inches long, simply or doubly pinnati- 
sect, with narrow or broadish lobes on the same plant. Nor do | think the discoloura- 
tion of the rays a more certain character. No one seems to haye noticed that some 
of the marginal flowers are constantly destitute of corolla, exactly asin Cotula, while 
others have a bilabiate-ligulate corolla; those destitute of corolla, though with well 
formed styles, are often abortive ; when fertile their achenes are muriculated, and 
such plants become (. anthemoidea, DC. I can only distinguish C. debilis, DC. by 
its somewhat broader leaf-lobes, a char. which he admits to be variable. The number 
of inv. scales, by DC. said to be 8, are surely often 12 or more; and possibly C. 
sub-heterocarpa, Less. should be added to the above varieties: FE. & Z.’s specimens 
at least are by me undistinguishable.

(Herb. D. , Sd.) : 
Seemingly perennial, rigid and ligneous at base, many stemmed ; stems 2-8 inches 
long, sub-simple, ascending, the older ones closely imbricated with the broad, pecti- 
nated bases of broken leaves, the young parts closely leafy. Leaves 1-1} inch long, 
copiously or more sparingly silky, the lobes simple or pinnulate. Pedunc. 3-6 inches 
long. Marginal fi. all ligulate-bilabiate.—Thunberg’s ‘‘ C. sericea,” composed partly 
of our ‘‘ Cotula sericea” and partly of “ Tanacetum linearilobum, DC.,” is quite different 
from the plant here described. :
