Willdenow in 1805 included in Croton (Sp. Pl. iv. 1, pp. 538- 
504) six species of Chrozophora:—20, tinctorium; 21, plicatum; 
22, obliquum; 23, verbascifolium; 59, moluccanum; 67, sene- 
galense. Two of these, C. tinctorium and moluccanum were, in 
intention, taken up from Linnaeus (1753); one, C. senegalense, 
was taken up from Lamarck (1786); two more, C. plicatum and 
obliquum were taken up from Vahl (1790); the last, C. verbaset- 
folium, was based on Tournefort’s Ricinoides ex qua paratur 
Tournesol gallorum, folio oblongo et villoso (1703). 
In dealing with C. tinctorium (l.c. p. 538) Willdenow dis- 
carded the varieties proposed by Lamarck in 1786, but added to 
the Linnean citations of 1753 that of Heliotropium minus, as 
figured by Gesner, and as understood by Camerarius. 
In discussing C. plicatum (l.c. p. 538) Willdenow was less

as Givotia rottleriformis, Griff. That species is not entitled to 
the epithet ‘molucanna’; the plant does not occ I 
Delica. We know that Linnaeus had no knowledge of ree
