BOTANY. 



Preliminary revision of the North American species of Cactus, 

 Anhalonium, and Lophophora, J. M.Coulter {U. iS. Dept. Ayr., Di- 

 vision of Botany, ContribnUons from the U. 8. National Herbarium, vol. 



3, No. 3, pp. 91-132). — The author gives a preliniiuary revision of the 

 North American species of Cactus (formerly Mamillaria), Anhalonium, 

 and Lopliopliora. The latter is a new genus based on Anhalonium 

 williamsU., to which are ascribed 1 species and a variety. Of the other 

 genera, 04 species and varieties of Cactus and 4 of Anhalonium are 

 described, many of which are reported as new. Brief notes are given 

 on the geographical distribution of the genera included in the revision.
