(1894). 

 Schrankia angustatal '. & G. Fl. N. A. i : 400 (1840). 



Specimens referred to this species were collected in fruit at Kenedy, 

 Carnes county, along the railroad embankment, altitude 400 feet, and at

 gia; Texas. 

 Morongia Roemeriana (Scheele). 



Mimosa Roemeriana Scheele, Linnaea, 21 : 456 (1848). 

 Schrankia platycarpa A. Gray, Bost. Jour. Nat. Hist. 6 1183 (1850). 



Abundant about Kerrville in stony or gravelly ground. Mimosa Roe- 

 meriana and Schrankia platycarpa are undoubtedly the same, as Gray 

 suggests in his publication of S. platycarpa, but refused to recognize 

 Scheele's plant because the fruit was not characterized. Acacia Roe- 

 meriana Scheele, described on the same page with M. Roemeriana is 

 described from flowering material only, and in addition has the error of 

 " flores rosei," yet it was accepted as a good species. The leaflets cf 

 the Kerrville plant are barely ciliate. They are like those of M. angus- 

 tata in being veinless, but are shorter and broader. The unusually 

 broad, flat legume, separates it at once from our other species. 



April 23 in flower, June in fruit (1634) ; type locality, " prope New 

 Braunfels." Scheele; "dry, stony, prairies.. New Braunfels." Gray.
