species, C. plicata and C. tinctoria. The former is C. plicata, 
Mill.-arg. (1866) in the wide sense in which all the forms with 
stellate-pubescent but not lepidote capsules are regarded as con- 
specific; it therefore includes the erect form with long racemes 
and purple capsules as well as the prostrate forms with condensed 
racemes and non-tinctorial fruits. The latter, however, is treated 
more critically, because Stewart has explained that the plant in- 
tended is not any of the four varieties of C. tinctoria segregated 
by Miller, but is the Indian plant issued by Wallich which 
Miiller referred to C. obliqua. It is further noticeable that 
Stewart, by citing this as C. oblongifolia, indicated that he had 
already appreciated the fact that Miiller’s identification of C. 
oblongifolia with Croton obliquum, Vahl, could not be accepted. 
In 1870 King (Pl. N. W. Prov. p. 15) accepted Stewart’s treat- 
ment. So, too, did Aitchison with regard to the species with 
lepidote capsules which he identified with C. tinctoria in 1880 
(Trans. Linn. Soc. Bot. n.s. vii. p. 108) and again in 1881 (Journ. 
Linn. Soc. xix. p. 186). The C. tinctoria of all three authors is 
not, however, the true ‘Tournesol’ of Europe but is C. hiero- 
sclymitana, Spr. (1826). é 
In 1887 Hooker supplied a critical account of the Indian species 
(Fl. Brit. Ind. v.) in which he has added a third species, C. 
ebliqua, to the two recognised by Stewart and King.

In 1906 Cooke supplied yet another critical revision of the 
forms from Western India (Fl. Pres. Bomb. ii.) in which the 
number of species is now increased to four; C. tinctoria, C. 
obliqua, C. plicata and C. prostrata.
