22. HOMALOBUs JUNCEUS Nutt. The duplicate of the type 
in the Torrey Herbarium is in fruit but shows a white-hairy 
calyx with very short calyx-lobes and leaves with no or very 
small lateral leaflets. Sheldon thought that this and Astragalus 
diversifolius represented but one species and applied the latter 
name to it, as the earlier A. junceus was preoccupied by A. 
junceus Ledet. Since, however, A. diversifolius is a synonym 
of H. orthocarpus, A. junceus, if transferred to Astragalus, would 
be without a name. This species is much more common than 
H. campestris. 1 shall therefore not enumerate any specimens. 
Most of those cited by Macbride under A. campestris belong here. 
Jones, as already noted, named the species A. diversifolius 
roborum. 
23. HoMALOBUs JUNCIFORMIS (A. Nels.) Rydb. The status 
of this species is somewhat problematical, since it has the short 
calyx-lobes of H. junceus and the black-hairiness of H. cam- 
pestris. It is stouter than either, with larger flowers and 
broader leaflets. Standley regarded it as identical with H. 
orthocarpus, but that species has smaller flowers and a much 
broader pod. The mature pod of H. junciformis is unknown, 
but the young pod suggests a similarity to that of H. junceus. 
Jones* made H. junciformis a synonym of A. diversifolius, 
evidently not being acquainted with the true A. diversifolius. 
The only specimens of H. junciformis seen are:— 
Wyominc: Fort Steele, A. Nelson 4839; Point of Rocks, A 
Nelson 3081; Leucite Hills, A. Nelson 4668. 
24. HOMALOBUS ORTHOCARPUS Nutt. The duplicate of the 
type in the Torrey Herbarium shows only the upper part of the 
plant, but Nuttall states that the lower leaves bear several 
leaflets, while the upper are more or less reduced to the rachis. 
This fact furnished Gray the name Astragalus diversifolius, 
when he found that A. orthocarpus was preoccupied by A. ort 
carpus Boiss. In H. orthocarpus the calyx is Shey. the 
lobes are deltoid and not much longer than broad, while the 
pod is much broader than in the related species, in the duplicate 
of the type being about 2 cm. long and 4 mm. wide. In the 
herbarium of the New York Botanical Garden the only specimen 
like the type is Goodding 1084 from Juab, Utah, which has been_
