VICIA AMERICANA, Muhl.- Valley of Salt Lake, June 1. CICBR ABIBTIKUM, Lin,- Sandy bottom land in ( he Valley of Salt Lake; probably introduced. This plant has also been found by Dr. Pickering on the banks of the Kooskooskee, or Clear Water, in Oregon; and I have received it from Southern California, where it was doubtless taken by the Spaniards. It is a little remarkable' that it should now be found apparently wild in the interior of Oregon and in the valleys of Utah. PHACA MOLLISSIMA, Nutt. in Torr. and Gr. FL 1, p. 350.

This plant is abundant in the Territory of Utah, and I have not received it from'any other region. It differs from the ordinary form of P . mollissima: a, ni if there were not what appear to be intermediate states of it, I should consider it a distinct, species. It is less branched, and has more numerous leaflets than the var. fi. The flowers are violet, four to six in number, in a short spiked raceme. The nearly mature legume is densely clothed with long woolly cream- coloured hairs, and very closely resembles that of P. moL lissima* Our plant has much the appear ance- of Astragalus gla-reosus, Doug\. ( A. argophyllus, Dougl.,) and which, I suspect, is a Phaca x but the leaves and fruit are different. Plate IL Phaca mollissima, var. utahensis of the natural sifte. Fig. 1, a flower.
