few flowering plants. The most fitting tribute of all was given 
by Schreber when he established the grass genus Muhlenbergia. 
That Muhlenberg was one of the best and most careful of 
American botanists is evident when one notes that very few of 
his species have gone intosynonymy. This is the more remark- 
able when we consider that in those early days facilities for work 
and communication with other botanists were very crude com- 
pared with the opportunities of the present day.

A RARE CENTROMADIA 
Y Centromadia Congdoni (Robinson & Greenm.) 
Flemizonia Congdont Robinson & Greenm. Bot. Gaz. 22: 
169. 18096. 
While collecting in Monterey county, California, in 1905, 
my friend, Mr. H. H. Bartlett, called my attention to the fact 
that Robinson and Greenman’s Hemzzonia Congdonz came from 
Salinas. I was not able to visit the locality until July 4, 1907, 
but then I collected a can full of a Centromadia which answers 
very well the description of AY. Congdonz. Mr. Bartlett has 
kindly compared my material at the Gray Herbarium and re- 
ports that it matches the type of A. Congdonz, tho not so pubes- 
cent. If the genus Cenxtromadia is to be recognized as distinct 
from Hemizonia, and we certainly consider it so, this plant 
should bear the above name. My collection of the species has 
been distributed under the number 1361.—CHAS, PIPER SMITH,
