very closely allied genus Linaria, separated from Antirr- 
hinum by the apparently trivial character of the sac of 
the base of the corolla of the latter being extended in the 
former into a spur, would have followed the same distri- 
bution. But it is not so. Linaria, of which there are 
about two hundred species, has only one North American 
representative, L. canadensis, which is common to the 
Eastern and Western States, and extends southward 
into Chili, In the Old World the genus attains its maxi- 
mum in Southern Europe and Northern Africa, reaching 
the northern tropic in the latter continent, and the 
Himalaya in Asia. 
Antirrhinum glutinosum is confined to the Sierra Nevada 
of Spain, where it is found on the walls of the Alhambra, 
and ascends to two thousand five hundred feet and upwards 
in the Sierra. Its nearest ally is P. molle of the Pyrenees, 
from which it differs in its long decumbent branches, 
glandular hairs, and larger broader leaves. It must not 
be confounded with A. glutinoswm, Brotero (Linaria fili- 
folia, Lag.), also a Spanish plant, which under its original 
name (of Antirrhinum) has escaped the notice of later 
botanists. The specimen figured was received at the 
Royal Gardens from Messrs. Backhouse, of York, in July, 
1892. It is a perennial, and requires the protection of a 
frame in winter.—J. D. H. 2
