NEW SPECIES AND NEW COMBINATIONS UNDER CRACCA. 
The need of a careful revision of the Mexican species known under 
Tephrosia has long been apparent to the writer, who has several times 
studied them with the hope of presenting a synopsis, but so many of the 
older species are still poorly represented in our American herbaria 
that it has not seemed hitherto nor does it yet seem wise to attempt a 
revision. Most of the existing descriptions have been studied, how- 
ever, and a large series of recently collected specimens have been 
examined, resulting in the description of a number of new species. 
The substitution of the older name Cracca also requires the making of 
a number of new combinations, a part of which are here presented. 
The excuse for publishing thus fragmentarily on this genus is that 
my correspondents desire names. in order that they may publish upon 
or distribute their material, and particularly. that several species are 
found to be the hosts of fungi and their names are wanted in this con- 
nection.
