i/ 37. C.ilSALPiNiA repens n. sp. Perennial, 9 to 13 cm. high, 



from slender, woody, creeping rootstocks; leaves and peduncles 

 crowded on a short stem, canescent with short, curled hairs; 

 leaves with from 5 to 7 pinnae, leaflets 4 to 6 closely appressed, 

 nerveless, with a few scattered, depressed glands varying in 

 shape, usually irregular in outline (many leaflets are without 

 the glands); stipules ovate-acuminate, petioles ribbed, a little 

 longer than the blade, with several long, lax bristles where the 

 pinnae join the axis, and one at the base of each leaflet; pedun- 

 cles stout, ribbed, surpassing the leaves, covered closely with the 

 short, white hairs, and with occasional longer ones similar to the 

 lax bristles on the leaves; flowers at first erect, closely clustered, 

 pedicels becoming deflexed and distant in the fruiting, elongating 

 raceme; four upper sepals lanceolate, lowest oblanceolate, cov- 

 ered with longer white hairs than the rest of the plant; without 

 glands, as is also the corolla; petals surpassing the sepals, obo- 

 vate, tapering to the short claw, 8 to 12 mm. long, 3 mm. broad, 

 smooth except the vexillum, which has a broad, hairj^ claw; 

 stamens with filaments about 10 mm. long, broadening at base, 

 smooth above, ciliate with blunt, coarse hairs below, densest at 

 the base; style cjdindrical, broadening at the base, and to a less 

 degree at the ciliate campanulate stigma, which is slightly 

 hairy below; legume at first canescent with short, curled hairs, 

 orbicular to obovate; in age with hairs so scattered that it is 

 no longer canescent, becoming reticulate with prominent trans- 

 verse veins, flat, with a thickened margin, varying from 

 orbicular to elliptical and oblong, usually abruptly pointed 

 with the persistent style, entirely without glands, i^ to 3 

 cm. long, i^ to 2 cm. broad; seeds usually two. This grew 

 in sandy soil, and formed loosely-spreading mats. It was col- 

 lected in Court House Wash, near where it comes into the Grand 

 River, on the opposite side from Moab, in southeastern Utah, 

 May 26, 1892. 



The pod is very difierent in appearance from that of others 

 of this genus. The character of its glands excludes it from 

 the sections proposed by E- M. Fisher in his recent revision of 

 Hofimanseggia. Since he has with good reason reduced Hofi"- 

 manseggia to Caesalpinia in Bot. Gaz. xviii, 4, this Utah plant
