60 PROCEEDINGS OF THE ACADEMY OP 



101. PSORALEA LANCEOLATA, Pursh. 102. P. FLORIBUNDA, Nutt. 103. P. ARGO- 



phylla, Pursh. 104. Daleaalopecuroides, Willil. 105. Petalostemonmacro- 

 stachyus, Torr. 10(3. Astragalus Kentrophyta (Kentrophyta montana, Nutt.) 

 107. Thermopsis rhombifolia, Nutt. (the smaller plant and the fruit), aud ap- 

 parently T. fabacea, var. montana, Gray ( T. montana, Nutt.) : the latter should 

 he known hy its taller stems, larger leaflets, and narrow, linear, pubescent, erect 

 legumes. 10S. Hosackia Purshiana, Benth. 109. Lathybus ornatus, Nutt., 

 and a pubescent variety. 110. L. linearis, Nutt. 111. L. polymorphs, 

 Nutt. 112. L. palustkis, var. myrtifolius? a small portion, and mainly 



VlClA AMERICANA, Muhl. 113. ASTRAGALUS RACEMOSUS, Pursh. 114. A. 



(Phaca, Hook.) bisulcatus, Gray ; in fruit. 130. Same in flower. 115. A. 

 (Phaca, Hook.) nigrescexs, Gray. 116. A. (Phaca, Hook.) glabriusculus, 

 var. major, foliolis anguste oblongis. Very likely, as Hooker conjectured, 

 a form of A. aboriginum. A narrow, membranous, rudimentary false septum 

 is borne on the dorsal suture, in the manner of A. Robbinsii and A. alpinus, to 

 which, indeed, the species is related. It was collected in the mountains, 

 "at middle elevation ; not common." 117. A. oroboides, Hornem. (Phaca 

 elegans, Hook.) " Along the bank of streams, at middle elevations, and subal- 

 pine." V^ry fine specimens, both in flower and in fruit ; the former with 

 linear leaflets, like the original P. elegans ; the latter with broader and glabrate 

 leaflets, just like Bourgeau's specimens from the Saskatchawan. 118. A. 

 flexuosus, Dougl. (Phaca flexuosa and P. elongata, Hook.) Legumes straight or 

 slightly curved. " Low mountains and plains ; common." 119. A. gracilis, 

 Nutt. With the last. 121. A. near Phaca deb His, Nutt., but larger in all its 

 parts. To be determined hereafter in a general revision of the species.* 122. 

 A. mollissimus, Torr., of which the stipules were wrongly described, a form 

 with silvery instead of yellowish pubescence. Fine specimens, same as Par- 

 ry's 184, doubtfully compared with A. glareosus, still without fruit. "On 

 the plains ; scarce." 123. A. Parryi, Gray ; now collected with ripe legumes, 

 which are so obcompressed and sulcate both sides that the sutures meet. 

 " Common both on the low mountains and subalpine.'' 124. A. Drummondii, 

 Hook. 125. A. alpinus, L. " From middle elevations to truly alpine." 126. 

 A. cyaneus, Gray, PI. Fendl. Specimens more luxuriant than Fendler's ; the 

 leaflets oval, half to two-thirds of an inch long, and young pods nearly two 

 inches long. This is likely to be A. Shortiamis, Nutt., of which I have seen 

 no specimens ; but the flowers are deep blue. " Low mountains, and rarely 

 subalpine; a fine species." 127. A. Missouriensis, Nutt. 128. A. sparsi- 

 florus, n. sp., to be elsewhere characterized in a revision of the North Amer- 

 ican species. " On low mountains ; rare." 129. Perhaps a variety of the 

 last, with more numerous flowers and larger legumes. 141. A. (Phaca) pau- 

 ciflorus, Hook. ? A glabrate, slender form, the same as Phaca pauciflora, 

 Nutt. " South Park, common, apparently a good forage plant." (Fendler's, 

 No. 144 is the same.) 130. A. (Phaca) bisulcatus, Gray, in flower. 131. A. 

 (Phaca) lotiflorus, Hook., very fine specimens in flower and fruit. 132. (fruit) 

 & 133. (fl.) A. caryocarpus, Ker. 134. A. (Phaca, Hook.,) pectinatus, Gray. 

 136. A. btriatus, Nutt. ! 137. A. (Phaca, L.) frigidus, with perfectly glabrous 

 legumes, as in other American specimens. " Subalpine, in wet pine-woods." 



138. A. (Phaca) filifolius, Gray, in Pacif. R. R. Exped. Phaca longifolia, Nutt. 



139. A. Hypoglottis, L. 145. A. (Orophaca) sericoleucus, Gray (Phaca seri- 

 cea, Nutt.) ; charming specimens of an interesting plant. 142. Homalobus 

 decumbens, Nutt. Also 435 of Parry, very sparingly collected. Its name as 

 an Astragalus can be settled only upon a revision of the species. 120. (and 

 433 of Parry,) Oxytropis deflexa, DC. 135. O. splendens, Dougl. ; worthy 

 of the name. 140. O. Lamberti, Pursh, with purple or blue, and with white 



* The name Astragalus debib's could properly be retained for Phaca debilis of Nuttall. For 

 there is no A. dehilis of Douglas; that so given in Walp. Repert. 1, p. 710, being an accidental error 

 for A. miser, Dougl.
