France, vol. xi. (1864) pp. 159-164) to 505. Several more 
have been added since, and Thellung in his masterly ‘‘ Flore 
adventice de Montpellier (1912),”’ p. 611, estimates the number of 
all the exotic species recorded so far from the classical spot at 
dei. The drying yards of Port Juvénal were abandoned about 
1880, and in 1905 Thellung found there only 10 species which 
had survived in the struggle with the autochthonous vegetation, 
most of them perennials, Stipa intricata, or as we must now 
call it. S. Neesiana, was not among them. It had been first 
observed by Touchy in 1847, and last by André in 1879. This 
excludes, of course, all connection between the Mortlake plant 
and Port Juvénal. It no doubt was introduced into the latter 
place more than once with different consignments of wool from 
South America, the imports from there beginning about 1830. 
When Port Juvénal was closed it still continued to come in 
and to spring up as a casual visitor in other places under similar 
conditions, such as the drying yards of Montplaisir, near Lodéve, 
and of Bedarieux on the river Orb, both in the Herault 
pointed out (in Verh. Bot. Ver. Pr. 
Brandenb. xl. p. lxxxi.) incidentally that it had been identified 
with certain specimens collected by Lorentz and Hieronymus 
near Siambon (Tucuman) and Catamarca in the Argentine. 
Ascherson and Graebner (Syn. Mittel-europ. Flor. u1. (1898) p. 
113) confirmed this statement, adding that Grisebach had named 
the Argentine plant referred to, S. eesiana, Trin., a deter- 
mination which seemed to them sufficiently doubtful to retain 
S. intricata as a distinct species. A comparison, however, of 
the Mortlake plant which is an exact counterpart of the Port 
Juvénal specimen in the Gay Herbarium at Kew with a co-type 
of S. Neesiana from Sellow’s collection, and the rather ample 
hess or hairiness of the leaves,
