known, and constitute the most important character of the 
genus. 
The following is the version of Mr. Brown's valuable de- 
finition of this curious genus. 
Receptacle chaffless. Seeds crowned by two opposite 
chaffs, and from one to three barbed awns. Calyx nearly 
equal, of many leaflets in one or two ranks. The species 
are herbaceous branching and slightly furred. Leaves alter- 
nate. General calyxes at the end of the branches, Solitary, 
nearly flat, foliaceous. Florets of the ray fertile, numerous, 
imbricated, blue, rolled back spirally after expansion, and 
lasting for a considerable time: florets of the disk barren, 
d-cleft, deep yellow. Anthers blunt at the base: seed, 
vertically compressed, cuneate. Seedcrown permanent, con- 
sisting of 2 dilated earshaped lateral chaffs (pale) broader 
than they are long, and of longer awns, generally two in 
number (one in front, the other opposite) and armed with 
small reversed prickles, either all the way from above the 
middle or only at the top. Receptacle pitted or lightly 
honeycombed, convex. 
Cuneifolia is distinguished from dentex by cuneate leayes 
deeply indented at the top. 
The drawing was made last summer from a plant at 
Messrs. Colville’s, in the King’s Road, which had been raised 
by Mr. Anderson in the greenhouse of the Physic Garden 
at Chelsea. ae
