206 LEAFLETS. 
able altitudes. They have a thin and ample foliage, quite 
green, usually appearing glabrous to the unaided eye, and the 
large whitish or purplish corollas which, together with the 
foliage, gives them the aspect of some Old World Malva and 
Lavatera species, from which they differ generically by their large 
truncate-subconic fruits, made up of 3-seeded dehiscent car- 
pels. But the fruit characters by which these two American 
types are generically separated may be more easily recognized by 
means of a brief and less informal statement. 
SPHABRALCEA, so called. Fruits small, from subtruncately 
broad-ovate to truncate-subconic, always densely stellate-tomen- 
tose, without other pubescence; carpels strongly fenestrate- 
reticulate laterally toward the base. Seeds stellate-roughened. 
ILIAMNA, Gen. Noy. Fruits 3 or 4 times as large, subtrun- 
cate-ovoid, the stellate pubescence both fine and sparse, over- 
topped by long hirsute simple hairs; carpels marked by no 
kind of reticulation or venation on the sides. Seeds roughened 
by minute simple hair-points, or in one species quite hispidulous 
with longer and denser but simple hairs. 
Of In1amNna, there are, I think, a considerable number of 
species yet to be given recognition over and above the old types. 
I shall merely indicate by name the old ones and define two that 
are clearly new, in so far as I can ascertain.

I. ACERIFOLIA. Nutt. in T. & G., under Malva. 
I. ANGULATA. Three feet high or more, the stem moderately 
stellate-pubescent; leaves with 3 to 7 lobes, all very broad and 
short, broadly triangular, the sides about equal, the margins of the 
lobes either very saliently or else slightly dentate; segments of 
calyx long, ovate-lanceolate, even somewhat acuminate; corollas 
large, apparently white: fruit not seen.
