moluccana, Linn. 
In 1812 Delile (Deser. Egypt. Hist. Nat. ii. Flor. Egypt. 
p. 139, t. 51, fig. 1) described and figured as Croton oblongifoliwm 
a plant collected by him at Ajeraud near Suez. This was the 
first valid name for a species which had already been obtained on 
two occasions; this is the plant in the Jussieu herbarium which 
Isnard a century earlier had wrongly identified with Lippi’s 
‘ Ricinoides memphiticus folio laevi,’ and is also the species col- 
lected in 1762 at Lohaja in Yemen by Forsk4l in whose Arabian 
list it stands as ‘ 562. Croton tinctorium ? ’ 
In 1815 Sibthorp and Smith (Fl. Gr. Prodr. ii. p. 249) des- 
cribed as a new species, Croton villosus, the plant which in 1703 
1790 as C. obliquum; and. Willdenow had again published in 
1805 as Croton verbascifolium. The same form, when discovered 
for the first time in Spain, was published once more by La Gasca 
in 1816 (Gen. et Sp. Nov. p. 21) as Croton patulus. 
Burm. f. (1768) non Linn. Roxburgh’s belief that it was 
C. plicatum was derived from Willdenow, a circumstance which 
proves that Willdenow had not informed Roxburgh that the speci- 
men of C. asperum which he had sent to Willdenow had been 
treated as part of the basis of C. moluccanum, Willd. non Linn. 
a, prospectus issued by Sieber in 1821 there are three 
references under Croton to species of Chrozophora. These call for 
attention because they are very generally cited by later authors. 
The first (Avis des plantes, p.5) relates to Croton tinctorium, Linn. 
from Girapetro, in Crete. The specimens are not exactly like the 
‘Tournesol’ of Southern France figured in 1557 by Clusius. 
They do, however, agree closely with the plant mentioned by 
Gesner in 1561 as having been raised at Padua from Cretan seed, 
and figured by him. The other two references (l.c. p- 7) are both 
to C. plicatum, Vahl, one of them noted in the Egyptian list, the 
other in the Palestine one. But the specimens show that the two 
plants are different; that from Egypt has stellate-pubescent 
capsules, and is nearly related to C. plicatum, Vahl; that fr 
Palestine, where it was gathered in the garden of tC tawaske: 
has lepidote capsules, and somewhat resembles, though it does not 
quite agree with, the Cretan plant cited as C. t L
