 the Paris Herbarium ; Estado de Morelos, F. Altamirano, 18 ; in the 

 United States National Herbarium. 



This is one of the most remarkable species in a genus abounding in 

 singular and elegant forms. It is exceptional, so far as my investiga- 

 tions go, in having distinctly pedicellate flowers, and the beautiful 

 appendages of the fruit are quite unlike those of any other species 

 known to me. The description and figure were prepared from 

 specimens in the Paris Herbarium, kindly lent by Prof. Bureau for 

 my intended monograph of the Mexican species. — W. Botting
