ever, Baillon has cited representative specimens which are more 
reliable than descriptions can possibly be. These species are : — 
1. Chozophora integrifolia, Bunge, based on Lehmann’s plant 
described by Bunge. 
2. C. sabulosa, Kar. et Kir., based on Lehmann’s plant cited 
by Bunge. 
3. C. tinctoria, A. Juss., the ‘ Tournesol.’ 
4. C. senegalensis, A. Juss., which includes ‘ Adanson n. 165’ 
the plant cited by Lamarck as the type of Croton senegalense; the 
plant collected by Adanson at Galam on which the description of 
Croton senegalense was based; and a specimen, ‘ Kotschy n. 28,’ 
from Abu Gerad in Kordofan which agrees with ‘ Adanson n. 165’ 
as regards tomentum on the under-surface of the leaf, but differs 
from both the Senegal plants of Adanson in having the leaves 
persistently shortly puberulous above. 
5. C. obliqua, A. Juss., based on the plant in Herb. Jussieu 
written up by Vahl as Croton obliquum. 
6. C. oblongifolia, A. Juss., represented by specimens collected 
by Bové and by Botta in Sinai, which agree with Croton oblongi- 
folium, Del. (1812). 
7. C. verbascifolia, A. Juss., which includes Croton verbasci- 
folium, Willd. and, with this, three specimens collected b 
Aucher (2008, 5297 from Persia: 2006 from Syria), all of them 
belonging to C. hierosolymitana, Spr., as does another unlocalised 
specimen collected by Botta.

specimen without field note, which agrees with Croton obliqui- 
folium, attributed on the herbarium label to Olivier: and 
9. C. obliquifolia [Vis.], Baill., based on a specimen of * Kot- 
schy n. 473,’ from Wolet Medine in Sennar, which agrees with 
Visiani’s figure of Croton obliquifolium.

In 1860 T. Anderson (Fl. Aden. p. 36) recorded C. obliquifolia 
from the coasts of the Red Sea and the Gulf of Oman. This 
record, which Anderson’s specimens prove to be correct, is of 
interest as showing that at t is late date no confusion had arisen 
as to the proper name of the species. In 1860 also, Baillon (Adans. 
i. p. 67) reverted to the forms from Senegal, recognising two 
species, one of them C. senegalensis, A. Juss., treated as Geisele 
treated Croton senegalense in 1807; the other C. plicata, A. Juss.,
