at least in the specimen figured by Langeron, lanceolate 
leaves. It occurs in New Caledonia. The nomenclatural 
basis of Langeron’s combination is unintentionally but 
nevertheless thoroughly confused due to the fact that 
Langeron, p. 34, cites “ Var. /3— angustifolia Vieillard 
(pro specie)” which would have been fairly clear even 
though in poor form if he had not proceeded to make the 
following statement on the next page: “Cette plante 
est tr6s probablement celle que Vieillard a decrite sous 
le nom d'A . angustifolia dans sa note sur quelques plantes 
interessantes de la Nouvelle-Caledonie et provenant de 
Pnebo-[sic, error for Puebo] Balade. ” This is not a mere 
pedantic quibble as to whether Langeron were describing 
a new variety or merely reducing Vieillard’s species to a 
variety. It involves the fundamental biological question 
of whether the two names are based on the same type 
and perforce synonymous or whether they are based on 
different types and in consequence are perhaps biologi¬ 
cally different. While I have accepted Langeron’s va¬ 
riety as being based on Vieillard’s species, ultimately it 
would be enlightening to examine the specimens at Paris 
in order to see exactly what Langeron had in mind. 
Langeron, in his vague reference to the article in 
which Vieillard published Aleurites angustifolia , gave 
the title of a paper of Vieillard published in the Bulle¬ 
tin de la Society Linneenne de Normandie 10 (1866)-- 
which was four years later than the correct reference 
given above. Furthermore, the article of 1866 did not 
mention Aleurites. A. angustifolia has been overlooked 
by Index Kewensis and all authors except Langeron. 
O. Stapf (Index Londinensis 1 (1929) 119) lists Lang¬ 
eron’s illustrations of vars. angustifolia and circulata. 
III. Var. y circulata Langeron, p. 35, fig. 7 (1902). 
The type, collected by Balansa in New Caledonia, is in 
the Herb. Mus. Paris. The leaves are essentially orbic-
