ON SOME SPECIES OF CRACCA 17 
Herbarium as ‘‘ 7’. virginiana Pers. var.’ The specimens both at 
the British Museum and Kew stand out from C. holosericea by habit 
and by the thicker leaflets, which are glabrous and shining above 
and silky and poy white beneath ; the racemes bear fewer and some- 
what smaller flowers. It is no doubt closely allied to C. holosericea, 
but, although with some remieheren we propose it as a species, of 
which the following i is a diagnosis : 
Cracea Seemanni, Hes? pi ecies certe C. holosericee valde 
affinis ; vdiffert j imprimis foliolis crassioribus subtus albo-sericeis, 
racemis paucifloris et floribus paulo minoribus 
Suffruticosa, caulis patentim sient conn + 3 dm. longus, 
stipulis lanceolatis acuminatis, petiolis communibus brevibus, foli- 
olis 11-19 coriaceis oblongis vel — oblongis mucronatis superne 
glabris subtus albo-sericeis 0-8-1: m. longis, + 0°5 cm. latis costa 
media in pagina superiore betes: in pagina inferiore prominente ; ‘ 
racemis terminalibus paucifloris et floribus interdum axillaribus, pedi- 
cellis gracilibus patentim villosis florentibus 1 cm.—1-3 cm. longis ; 
antes immaturis albo-sericeis. ‘Flores eri ’ (Seemann).

for rast Benth., the name Cracca having already been employe 
generically for a section of Vicia. Dr. Kuntze, having mR com

refer to Cracca Benth., and it seems worth while to bring together 
the plants which have been setiniead to it and will ane to be placed 
under Benthamantha. The employment of the e Cracca for 
three distinct groups of ohaiia has already le led to cutaaeill + and, 
until botanists have agreed either to maintain Cracca or Tephro 
Pers. or to retain the latter name, further age ties will inevitably 
arise. Dr. Millspaugh, for example (Contrib. Fl. Yucatan, 1. 22), 
places under Cracca (. cinerea aha C. ta a nts representing 
two genera; in Contrib. ii. 299 he describes a new species, 
Greenmanii, which apparently belongs to Benthamantha, but again 
— next to it C. cinerea (Tephrosia cinerea Pers.); in Contrib.

1898, 498) rs the’ numbering of its pages in two series, each in Arabic n l 
differing only in the thickness of the type, as ‘‘ apt to cause confusion.” This
