THE FORMS OF SALVIA VERBENACA 147 
In June, 1906, oo plant came under my observation at Deal, 
where I examin ed large number of spikes eter

During the tie a wclivhioe of 1907 I received fresh specimens 
ga atierdd’ near Guildford, and saw the plant growing in quantity 
in the same spikes, th ¢ forms varying from a small one, 6 mm. 
long and hardly siteading the calyx, with equal closely sonstdlvedl 
lips and the sexual organs included, to a larger erandrous 
seemed to produce a mixture of spineniédiats and ogres oom 
flowers. A feature of the corolla which is well see ) 
terandrous flowers, but which is obscured, though still ae 
in the smaller closed corollas, is the occurrence of two white spots, 
surrounded with dark purple, in the throat at the base of the 
lower lip. This was remarked equally in all of the localities, and 
is very fairly shown in Jordan and Fourreau’s figure of Galiitri- 
chum anglicum. 
In the following September the same plants in Gloucestershire 
and Middlesex, being still in bloom, were re-examined, together 
with others in two spots near Torquay, but a this date no pro- 
terandrous flowers whatever could be found, the largest corollas 
being of a small, intermediate type mingled with an abundance of 
others pier Sena mer 
ese 0 would seem to show that the form of the 
corolla in British habitats is not only polymorphic but very irre- 
gularly so, and depends largely on the locality and season, with a 
great prevalence of cleistogamous and semi-cleistogamous flowers 
at all times and the chief development of proterandrous corollas 
early in the summer—in all of these particulars agreeing with 
great exactness with the account of isis flowers and their fertili- 
zation which we owe to M. hs uet. 
The plant growing at the Lizard which arrested a attention 
_ in 1902 owing to the size of its flowers is a tall dark form, more 
than usually glandular, with broad, deeply-cut leaves resembling
