SOME MEXICAN SPECIES OF CRACCA, PAROSELA, AND 
MEIBOMIA. 
(WITH PLATE V) : 
THE genus name Cracca of Linnaeus (1753) has of late years been 
Testored in place of the Tephrosia of PERsoon (1807), which is clearly a 
synonym, as has been well pointed out by Mr. E. G. BAKER.' 
Dalea, although first proposed by Lrynagus in 1737, was reduced by 
him in 1753 to Psoralea. It was not restored until after PATRICK BROWNE 
in 1756 had published his Dalea, and therefore the next available name, 
Parosela, must be used. 
The Meibomia of ADANSON (1763) has properly been taken up in place 
of Desmodium (Desvaux, 1813), which must be treated as a synonym, 
though there is some ground for regarding the two names as representing 
different genera. 
n examination of these three genera by Mr. RosE in connection with 
his Studies of Mexican plants has shown that they are greatly in need of 
Tevision, and considerable work has been done with a view to meeting this 
want. Mr. ParnTer has a revision of the Mexican and Central American 
Species of Meibomia well advanced. It was not the intention to publish 
any notes on these genera until our revisions were completed; but there has 
been considerable demand, both from general collectors and from botanists 
© have been working on Mexican fungi, for correct names for certain 
Species; and we have concluded to publish a few of the new combinations 
and new species at the present time.
