Regel and Herder in 1869 followed the recently published work 
of Miller; Kuntze on the other hand in 1891, when changing the 
generic name to Tournesolia, followed Boissier as regards the 
specific one. In 1912 Pax and Hoffman have once more adopted 
for the only species of the group the name Chrozophora sabulosa 
which, though not the oldest, is the one under which a descrip- 
tion was first given.

The number of forms admitted in the group Tinctoriae has 
varied somewhat. Tournefort in 1703 recognised two species 
of Ricinoides ex qua paratur Tournesol gallorum, which he dis- 
tinguished as folio oblongo et villoso, and as folio serrato non 
villoso respectively. Willdenow in 1805 nominally distinguished 
three :—Croton tinctorium, Linn. (1753); C. obliquum, Vahl 
(1790); and his own C. verbascifolium, based on Tournefort’s 
Ricinoides . . . . folio oblongo et villoso. In reality, 
however, Willdenow only dealt with two species because CU. 
verbascifolium is the same as the older C. obliquum.  Geiseler
