" 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 

 Ldvaierd 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. 



Sp^aeralcba, so called. Fruits small, from subtruncately 



broad-ovate to truncate-subconic, always densely stellate-tomen- 



j tose^ without other pubescence; carpels strongly fenestrate- 



reticiilate laterally toward the base. Seeds stellate-roughened. 



iLtAMNA, Gen. Nov. Fruits 3 or 4 times as large, subtrnn- 

 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 Iliamna, 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. KIVULABIS. Dougl. in Hook. Fl. under Malva. 



I. ACEKIFOLIA. Nutt. in T. & G., under Malva. 



I. ANQULATA. Three feet high or more, the stem moderately 

 stellate-pubescent ; leaves with 3 to 7 lobes, all very broad and 

 shortlbrb^dly triangular, the sides about equal, the margins of the 

 Jlobes either very saliently or else slightly dentate ; segments of 

 calyx long, ovate-lanceolate, even somewhat acuminate ; corollas 

 large, apparently white: fruit not seen.

 d feet iii^h, bushily branched from base and throughout; stems 

 and foliage quite densely stellate-pubescent; leaves of firmer
