1. Oxybaphus nyctagineus (Michx.) Sweet. (See Field Mus. Nat. Hist. 

 Publ. Bot. Ser. 8: 305. 1931.) (Allionia nyctaginea Michx.) Heartleaf 

 Umbrella- wort. Map 889. Infrequent to frequent in railroad ballast

 Roselawn in Newton County, and once in a very sandy, oat field near 

 Kniman in Jasper County. 



Ind. to Man., southw. to Tex. and Mex. ; frequently adventive in e. U. S.

 and to the fact that grazing animals do not molest it. I have seen 

 it only a few times in a thick stand over any considerable area. I once
