this species in existence. From the only locality known in 
the world where it is found over an area of a few square yards.

thium spinosum in Neolithic deposits in Bulgaria. 
Xanthium spinosum is one of the commonest ruderal plants of 
Central Europe and the Mediterranean region. It has generally 
been considered by recent writers to be a native of South America. 
The strong arguments in favour of this view will be found 
summarized by Thellung in his Flore adventice de Montpellier, 
pp. 505-506, and many references to earlier literature on the 
subject will be found there. 
Millspaugh and Sherff in their Revision of the North American 
Species of Xanthium, Field Museum of Natural History, Botanical 
Series, Vol. iv., No. 2; p. 14, April 1919, give the distribution 
as follows :—* Now generally distributed almost throughout the 
United States; found also in South America, where probably 
native, Central Europe, “western Asia, southern Africa and in 
Australia’.’’ It should also be pointed out that the centre of 
distribution of the genus is vertaiily to be found in the New 
World 
other opinion, which was current among earlier botanists, 
that Xanthium spinosum was native in South Russia, was rejected 
by Ascherson (Verhandl. bot. Ver. Brandenb. xvii., 1875, Sitzb., 
p: 12, and Le. xxii., 1880, Sitzb., p. 89). It may also be noted 
that according to L. Simonkai a Karl Flatt (Bot. Centrlb. 
. lv., 1893, p. 365) both A. Florentin and also C. Spegazzini 
have collected fossil fruits (‘‘ false-fruits”) of X. spinosum 
from the Pliocene beds in the Tertiary formation of the Pampas. 
uring a visit to Bulgaria last summer Dr. N. Stoianoff of 
Sofia University gave me some semi-fossilized fruits which 
careful comparison at Kew has shown to be those of Xanthium 
spinosum. These were obtained during excavations in prehistoric 
deposits near the village of Bogorow, 15 km. east of Sofia.
