Netson: New Prants FROM WyoMING 401 
branches inconspicuously if at all barbellulate : akene obovoid, 
shorter than the body of the scale. 
The above description had been drawn before I was aware of 
Mr. Coville’s variety of H. micrantha Vahl, which does not appear 
in Heller's recent Check-list of North American plants. After 
carefully considering all that appears in Mr. Coville’s excellent 
_ and complete discussion of the genus I am still of the opinion that 
the plant deserves specific rank. Besides the characters pointed 
out by Mr. Coville which separate it from A. micrantha, decided 
differences in size and form of the floral structures are to be 
noticed. The following collection greatly extends the range of 
this species. It was found in a moist, sandy cafion, altitude 2000 
m., in company with Cyperus inflexus. Halleck cafion, Albany 
county, July 4, 1goo, no. 7428.

As there is a variety montanus of J. Balticus, this plant, which 
_ Seems well to deserve specific rank as well as a separate name 
within the genus, may take the above as indicating its center of 
distribution. 
* Trifolium scariosum 
Densely caespitose, silvery or cinereous-pubescent throughout, 
becoming greener and more glabrate with age; the caudex freely 
branched and clothed with the dead petioles ; stemless or nearly 
So: leaves crowded on the crowns; the leaflets narrowly linear- 
oblong, widest at the middle and tapering gradually to each end, 
1.5-2.5 cm. long, sessile or nearly so; the petioles slender, from 
twice to several times as long as the leaflets : peduncles surpass- 
ing the leaves, like the leaves prostrate-spreading or ascending: 
the adnate portion of the stipules broad, sheathing, scarious-mar- 
gined ; the free portion linear-acuminate, reduced to merely the 
Steenish midrib, less than 1 cm. long: involucre usually (always?) 
present, of several very unequal scarious-margined linear-lanceo- 
ate segments: heads globose, rather few-flowered: calyx-tube 
short, Narrow-campanulate ; its teeth linear, unequal, exceeding or 
often twice as long as the tube, purple as is also the upper portion 
of the tube : corolla purple, fading in drying ; the standard broadly 
elliptic, equaling and enclosing the wings which exceed the keel 
petals: pod 6-ovuled, fewer seeded: the style slender, as long as 
the pod.
