According to Kuhn, Bot. Ztg. xxv. 67 (1867), species of Amsinckia 
are dimorphous. Darwin, Different Forms of Flowers, 110 (1877), 
denied that this is the case, there being simply a large amount of 
variation in the length of the styles and the insertion of the sta- 
mens. But Dr. Gray, Syn. FI. ii. pt. 1. 197 (1886), wrote “ Flowers 
in most species all heterogene-dimorphous, at least in the insertion 
of the stamens.’”’ However this may be, an examination of a large 
number of specimens of A. tessellata Gray, the closest ally of A. 
Lemmonii, has shown no sign of such variation (or heterostylism) 
so that the characteristic seems to be peculiar only to certain species, 
and therefore may be considered valuable for purposes of classifi- 
cation. A. Lemmonii is a case in point, since, in contrast to A. tes- 
sellata, it possesses this variation. In Jared’s specimen the stamens 
are inserted low in the tube and the style is long; corollas of Lem- 
mon’s specimens have the stamens at the throat and the style 
short, but both specimens obviously represent only one species 
because they are otherwise identical. However, the recognition of 
A. Lemmonii as a species does not depend on the validity of this 
character, for it is strikingly distinct from A. tessellata in its large 
corolla which gives it the aspect of the remotely related A. grandi- 
flora or A. spectabilis. Although it has the distinctive tessellated 
nutlets of its nearest relative, they are much narrower than those 
of that species in proportion to their length. Miss Alice Eastwood, 
when studying at the Gray Herbarium, wrote on the sheet of the 
Jared specimen ‘“‘n. sp.” She has kindly given me permission to 
describe it, and, since the discovery that the Lemmon specimen 
Hoa with it, she has expressed pleasure over my choice of
