846 PROCEEDINGS OF THE AMERICAN ACADEMY 



Collected in Southern Utah on Col. Powell's expedition by Mrs. E. P. 

 Thompson and Capt. F. M. Bishop. 



Astragalus (Homalobi) sesquiflorus. Near A. paucijlorus 

 of Oregon and British America, but differing in the 1-2-flowered 

 raceme equalling the leaves, the keel terminating in a long straight 

 beak, and in the gibbous slightly compressed pod. Casspitose ; pubes- 

 cence appressed silky-canescent ; stems very slender, 2-4 inches long ; 

 leaflets 2-5 pairs, linear-lanceolate and acute at each end, 3-4 lines 

 long ; calyx campauulate, with linear-setaceous teeth longer than the 

 tube ; flowers purple, 3-4 lines long, a little exceeding the calyx ; pod 

 membranous, 4 lines long, attenuate to the base. — Southern Utah, 

 collected by Capt. F. M. Bishop, 1873. 



Astragalus (Homalobi) episcopus. Somewhat canescent with 

 short appressed hairs, glabrous below ; stems slender, erect or ascend- 

 ing, l-|-2 feet long, branched; leaflets distant on the slender rachis, 

 1-3 j^iiii's or sometimes none, narrowly linear, acute, 4 lines long; 

 flowers scattered in a short raceme, purple or yellowish ; calyx short, 

 cylindric, 2 lines long, with acute triangular teeth ; banner 6 lines 

 long, exceeding the wings and the sti-aight scarcely beaked keel ; pod 

 narrowly oblanceolate, compressed, 1^ inches long, 2| lines broad,- 

 acute at each end, very shortly stipitate, reflexed. — Resembling A. 

 junceus from which it is separated by its larger straighter flowers, 

 longer calyx with more acute teeth, and by its much broader pod. 

 Southern Utah ; Capt. F. M. Bishop. 



Cercocarpus intricatus. (O. hrevijlorus, "Watson in King's 

 Rep. 5. 83, not of Gray.) Distinguished from C. ledifollus, to which 

 it is perhaps most neai'ly allied, by its low shrubby rigid and intri- 

 cately branched growth, by its short closely revolute leaves, and by its 

 much smaller flowers and fruit. The little known C. brevijlorus of 

 New Mexico, with a somewhat similar habit, has still smaller flowers, 

 and the cuneate oblong leaves less coriaceous, strongly nerved, and 

 more or less silky puberulent; its fruit is unknown. The present spe- 

 cies was frequent on rocky mountain sides near the mouth of American 

 Fork Canon in the Wahsatch (314 Watson), and has been recently 

 collected by Parry (n. 59) near Saint George in Southern Utah. 



AsARUM Hartwegi. {A. Hooheri, var. majus^ Duchaitre in DC. 

 Prodr. vol. 15, part 1, p. 424.) A stouter species than A. caudatum, 

 Liudl., {^A. Hookeri, Fielding), growing in thick tufts with shorter root- 

 stocks and peduncles, and usually more pubescent especially at the 

 base and upon the calyx ; leaves mottled ; flowers half an inch broad, 

 the calyx-lobes leathery, ovate and attenuate to a flliform apex, 1-1 1
