Aletes MacDougali C. & R. Cont. U.S. Nat. Herb. 7: 107. 1900. 
This was doubtfully referred to Aletes by Coulter and Rose. 
The fruits in the type collection were very young and did not 
show their true nature. Anyhow, they showed distinct wings, 
a character inconsistent with the genus Aletes. Professor Garrett 
and myself collected good fruits in southeastern Utah in the 
summer of 1911; and these show that the plant is rather an 
Oreoxis than an Aletes, wings being present and these thick and 
corky. The two genera are, however, more closely related than 
has been recognized, having the same cespitose habit, the promi- 
nent calyx, teeth, etc. 
Daucophyllum (Nutt.) Rydb. gen. nov. 
Musenium § Daucophyllum Nutt.; T. & G. Fl. N. Am. 1: 642. 
1840, 
Low cespitose perennials, acaulescent or nearly so, with a 
branched caudex. Leaves numerous, basal, or 1 or 2 cauline, 
pinnate or bipinnate with filiform or narrowly linear divisions. 
Flowers cream-colored to yellow, in dense umbels. Bracts want- 
ing; bractlets few, narrow, linear. Calyx teeth prominent. 
Stylopodium wanting. Fruit ovoid or oblong, granular on the 
intervals. Ribs equal, rather strong, but not at all winged. Oil 
tubes 2 or 3 in the intervals, 4-6 on the commissural side. Seed 
terete or somewhat depressed; face plane. 
The type, Musenium tenuifolium Nutt., was separated as a 
section in Torrey and Gray’s Flora. The relationship is rather 
with Harbouria and Aletes than with Musineon Raf. The first- 
mentioned relationship was recognized by Coulter and Rose (see 
their Revision, p. 111). It differs from Harbouria in not having 
thick corky ribs and in having several oil tubes in the intervals. It 
is still more closely related to Aletes, having the same habit, although 
narrower leaf-segments, the main differences being, however, the 
solitary oil tubes in Aletes and 2 or 3 in each interval in Dauco- 
phyllum, and the concave seed face in the former and the plane —
