species of Chrozophora. No Chrozophora with lepidote capsules 
has ever been met with in the presidency of Bombay to the south 
of Scinde: The specimens cited by Cooke all have stellate- 
pubescent capsules. Therefore C. tinctoria, Cooke (1906), non 
. Juss., is precisely equivalent to Uroton tinctorium, Burm. f. 
(1768), n n Linn. 
a cbligua Cooke, is exactly equivalent to U. obliqua, Mill.- 
arg. (1866), non A. Juss., and therefore is in reality C. oblongi- 
folia, A. are (1826). 
3. C. plicata, Cooke, is exactly equivalent to Croton plicatum, 
Roxb. dsi4),. non Vahl, and therefore is in reality C. Rottleri, 
A. Juss. (1826). 
4. C, prevent, Cooke, is in intention equivalent to C. prostrata, 
Dalz. (1861). In practice, however, it also includes C. parvifolia, 
Klotzsch (1862), and that the limitation of the species was still 
further misunderstood we know from the circumstance that Cooke 
has included, by citation, under Dalzell’s species, the African 
C. plicata, A. Juss. (1826) which is Croton plicatum, Vahl (1790). 
History oF THE Orrentat Specres, 1879-1915. 
When in 1879 Boissier described the species of Chrozophora 
from the Orient (Fl. Orient iv.) he dealt with six different forms: 
—Chrozophora plicata, C. gracilis, C. tinctoria, C. tinctoria var. 
subplicata, C. verbascifolia, C. obliqua 
1. C. plicata, Boissier’s specimens of which came tery oo 
African part of his area, has already been he ed. The 
tions under this African species of C. Rottleri, A. Juss. (1826) 
and C. prostrata, Dalz. (1861), neither of whith occurs in the 
‘ Orient,’ suggest that the species was not fully understood. 
2. C. gracilis, from Central Asia, is the plant so named by 
Fischer and Meyer in 1839 and described under their name by 
Ledebour in 1850. But this species is identical with C. sabulosa, 
named and described by Karelin and Kirilow in 1842 and 
described again under their name by Ledebour in 1850 and by 
Miller in 1886. Miller thus used the name with which a 
description was first associated, Boissier used the name which was 
first applied, without description, to this plant. 
3. C. tinctoria, by the specimens cited, utes besides those 
that are referable to Croton tinctorium, Linn. (1753) some that 
are really referable to Chrozophora Sept Berne eine Spr. (1826 
3b. C. tinctoria var. subplicata, which is confined to Lower 
Egypt, has already been discussed. 
4. C. verbascifolia is no longer the natural species named 
Croton verbascifolium by phe cade - 1805 but is eaicresamng to be 
" C. “pbli ua, as Selcnzied by Boissier, was meant to be ¢. 
obliqua, Mill.-arg. and therefore to be identical with. Croton 
oblongifolium, Del. (1812). In practice, however, C. obliqua,
