This is supplemented by an enumeration of those collected in 
1890 by the expedition from the Philadelphia Academy under 
Prof. Heilprin, nine species, Bouteloua Americana and B. Triena 
being new names. 
Mexican Jumping Beans, and the Plant Upon Which They are 
Produced. C. V. Riley. (Am. Gard. xii. 552-554; illus- 
trated). 
The curious seeds known as “jumping beans ” are described 
as the seeds of certain new species of Sedastiana, viz.: S. Palmert, 
Rose, and S. Pringlet, Watson, from Mexico. Their peculiar 
movements, from which the name is derived, are due to the inclu- 
sion of the larva of a moth (Carfocapsa saltitans) whose motions 
cause the “jumping” when the beans are slightly warmed by 
contact with the hand. Similar phenomena are also noted in the 
seeds of Colliguaja odorifera from South America.

New or Noteworthy Species. Edward L. Greene. (Pittonia, ii. 
167-173; advance sheets). 
The following are described as new: Lvigeron multiceps, from 
California, (Palmer and Wright, No. 121), &. coronarius from 
_ Chihuahua, (Pringle, No. 1275), Z. stolonifer, much of which 
has been distributed as &. /fagellare, from Colorado. The 
genus Achetogeron is not considered distinct from Lrigeron, and 
its species are all placed in the latter. Aplopappus Brandegeei, 
A. Gray, is also regarded as an Lrigeron, notwithstanding its 
yellow flowers, and named &. aureus. Aster Elmeri, Arcto- 
staphylos patula, A. media, Rhododendron Sonomense, and Erio- 
gonum elegans, all from California or Washington, are also here 
characterized. 
Nomenclature—Some Neglected Priorities in Generic. Edward 
L. Greene. (Pittonia, ii. 173-184, advance sheets). 
Professor Greene continues his researches into older generic 
names than those in common use, and points out that Jacksonia, 
Raf., (1808) antedates Po/anisia of the same author, (1819), and 
Jacksonia, R. Br., (1811); Kraunhia, Raf., (1 808), is older than 
’ Wisteria, Nutt., (1818); Psilotrophe, DC., (18 38), should replace 
_ Riddellia, Nutt., (1841), not Raf., (1836); Agoseris, Raf., (1817),
