 clauso rotundato-cordatatis denticulatis brevi-aeuminatis (nonnullis 

 obsolete triIobi<) utrinque albido-velutinis ; petiolis ramisque molliter 

 puberulis; pedunculis infimis petiolo longioribus ; calyce pedicello cap- 

 sulaque 8-earpellari molliter villosissimo, carpellis membranaceis 3-4- 

 spermis breviter acuminato-rostratis. — Yaqui River, Sonora, Mexico,

 diameter. Corolla orange-yellow, more than an inch in diameter. 

 Seeds in one row, nearly glabrous. 



Kostelktzkya digitata, ii. sp. Minutissime stellulato-pubescens 

 cum stellulis adpressis majoribus ; ram is paniculatis ; foliis 3 — 5-parti- 

 tis, petiolo setoso-hispido, segmentis cum foliis simplicibus ramulorum 

 linearilanceolatis denticulatis subtus setis triradiatis conspersis; pedun- 

 culis unifloiis gracilibus ; calyce tantum puberulo ; capsula 5-carinata 

 ad suturas setosa ; seminibus glabris. — Yaqui River, Sonora, Mexico, 

 Dr. E. Palmer, 1869. Corolla little over half an inch in diameter, in 

 the dried specimens purplish with a yellow eye. 



Desmodium Ielixoense, n. sp. D. canescentem foliis floribusqne, 

 D. rigidum racemo et fructu referens; caule erecto 3— 5-pedali cum 

 foliis pube brevi birsutulo ; foliolis ovatis oblongis seu ovato-lanceolatis 

 obtusis (poll. 2-4 longi.-) subcoriaceis subtus cinereis venis venulisque 

 prominulis eximie reticularis, inferiorlbus petiolum subaequantibus ; 

 stipulis persistentibus (bracteisque caducis) ovato-lanceolatis sensim 

 acuminatis striatis ; racemo simplici; lomento brevissime stipitato vix 

 ultrapollicari ad suturam utramque (infer, profundiorem) sinuato, 

 articulis 3-5 ovalibus lineas 3 baud excedentibus. — Illinois, in dry 

 ground, Vasey, Hall, Bebb, Bergen, Stewart, &c. ; apparently common, 

 but not yet detected beyond the limits of that State. Smaller speci- 

 mens have been confounded with J), rigidum, and larger, without fruit, 

 with D. canescens ; but it is abundantly different from both.
