 centes, Crotoniformes, tomento albido stellulato denso scaberulo ; foliis 

 ovato-cordatis oblongisque ; pedunculis axillaribus unifloris.

 calyce triple longioribus ; carpellis 10-12 monospermis (ovulis 2 superi- 

 oribus abortivis) ; parte superior! vacua ante maturitatem bipartita et

 356. N. W. Sonora, Mexico, about 100 miles below the U. S. boun- 

 dary, Pringle, — It is most proper that one of the new plants which 

 Mr. Pringle collected at much risk of life, in the northwestern corner 

 of Sonora, should commemorate his able associate in practical botani- 

 cal labors, Frederick Hinsdale Horsford, of Charlotte, Vermont. Hav- 

 ing a second species to add, T may perhaps take leave to join the name 

 of my own former associate, Eben N. Horsford, of Cambridge, the well- 

 known chemist, whose services and gifts to the scientific department 

 of Wellesley College will more worthily immortalize his memory. The 

 second species is 



H. Newberryi. Fruticosa; petalis (ut dicitur) loete flavis dimidio

ANODA, Cav. A critical examination brings to light carpological 

 differences among the species of this genus which had only partially 

 been detected before, and had not been worked out. The subjoined 

 arrangement of the forms known to me will exhibit these points of 

 structure, and to a certain extent set right the nomenclature of at least 

 the North American species.f

§ 1. EvANODA. Seed and ovule horizontal or nearly so in the mostly beaked 

 carpels of the much depressed and radiatiform fruit, naked, or in one species 

 •with an arilliform pellicular fragile coating, the disk or upper face of the fruit 

 strongly hispid or hirsute. 



* Corolla violet or purple, varying occasionally to white : fruit mostly surpassed 

 by the widely spreading calyx, the top beset by scattered simple bristles :
