 ■7 lin. longis pendulis ; foliolis majoribus 6-8 lin. longis crebre glanduloso-puncta- 

 tis. — Mountains at Guadalupe Pass,* between San Bernardino, Sonora, and the 

 copper mines, Sept. ; in fruit. (980.) — The leaflets are still larger than tliose of 

 Wrighfs No. 116, of which the fruit is not known. The legumes are ncarly twice 

 as large as those of Lindlieimer's No. 374 and CouIter's and Gregg's Mexican 

 specimens, in which they are ascending on the rhachis and falcate-incurved ; in the 

 present plant thcy are linear, straight, and all deflexed. If further specimens do 

 not tend to unite them, the present plant must be distinguished specifically. But 

 Schauer describes thc fruit of his Mcxican spccimcns in Aschenborn's collcction as 

 lanccolate, a little arcuate at the apex, 7 lines long and 2 lines wide.
