The locality Mayotte in the Comoro group given by Miiller 
on the authority of a specimen in the Lenormand herbarium is 
erroneous. The field note which accompanies a specimen of this 
particular gathering (Boivin, 1074) shows that it was obtained 
by Boivin at Berbera in Somaliland. The Panjab locality cited 
by Pax and Hoffman and the Indian locality indicated by Miiller 
the citation by Pax and Hoffman of Croton argenteum, Forsk. 
(1775) non Linn.; Croton obliquum, Vahl (1790) and Chrozo- 
phora obliqua, A. Juss. (1826). The same actual specimen in the 
Copenhagen herbarium serves as the type both of Forskal’s 
species and of that of Vahl; the type of Jussieu’s species is an- 
other specimen of the same plant in the Jussieu herbarium writ- 
ten up as Croton obliquum by Vahl himself. Clearly therefore all 
three names must be cited under one species, not distributed
