Echinocystis.—The Western Species of —E. L. Greene. (West. 
Amer. Sci., iii., pp. 34-35.) 
Prof. Greene contends that the cucurbitaceous plants de- 
scribed as species of Megarrhisza are not to be generically sepa- 
rated from Echinocystis, which would thus consist of seven west- 
ern species and our eastern £. /obata. : 
Eupatorium ageratoides. (Vick’s Ill. Month. Mags <x. -p. 50.) 
The writer strongly recommends the use of this species for 
decorative purposes. It is said to bloom a month earlier than 
the £. arboreum, which it much resembles. In places where it 
blooms in profusion, it is one of the most showy native plants.
