224 PITTONIA. 
venulose, those of the long-peduncled radical leaves about 
an inch long, oval or obovoid, some angularly lobed, trun- 
cate or retuse, unevenly dentate, the cauline lanceolate or 
oblong-lanceolate, 13 inches long, more saliently toothed, 
some of the teeth retrorse: stipules very small, only 2 or 3 
lines long, entire: heads large, the corollas 4 inch long, soon 
deflexed: calyx pubescent, with short tube and not much 
longer setaceous teeth. 
Known only from specimens collected somewhere in south- 
ern Utah, by Dr. Palmer, in 1877. In characters of leaf and 
flower much like T. Howellii, but in habit more like 7. 
Kingii, but that has ample stipules, very veiny leaflets, and 
a very firm and substantial texture of foliage, while T. maci- 
lentum is marked by an altogether characteristic thinness of 
leaf, in which particular T. Howellii, but no other native 
typical Trifolium, makes an approach to it. 
ASTRAGALUS PAUPERCULUS. Annual, erect, slender, only 
2 to 6 inches high, sparingly branched; cinereous with short 
appressed hairs, except the glabrous upper face of the leaves 
and the blackish-hairy calyx: leaflets in 4 or 5 remote pairs, 
oblong, truncate, scarcely 2 lines long: peduneles filiform, 
surpassing the leaves, somewhat capitately 2 to 4-flowered : 
calyx campanulate, the subulate teeth only half as long as 
the tube: corolla purple, the banner 2 lines long or more; 
ample and conspicuously surpassing the other petals: pods 
$ to 1 inch long, faleate, somewhat flattened, the cross-sec- 
tion narrowly obcordate. 
A diminutive species, first collected by myself now more 
than twenty years since, on a dry hillside of the upper Sac- 
ramento, but in flower only; and I could never determine 
whether it would be of the short-podded group to which 
A. didymocarpus belongs, or an ally of A. tener. Fruiting 
specimens sent in recently from the same district indicate 
its close relationship to the latter, and to A. Rattani.
