PLAGIOCHILA 181 
is, however, present in every district which has been 
searched. I have seen some hundreds of specimens from all 
over the country and from every county, so that its local 
distribution is not here given. It grows in many kinds of 
situations, both moist and dry, and on different formations. 
Perianths and male plants are both rather common, but 
fruit is somewhat uncommon, and is usually seen when on 
moist shady rocks; it is mature from April to June and in 
September. 
The var. minor in its characteristic form, which we know 
as P. Dillenii Tayl., is frequent on boulders and rocks in 
moist subalpine ravines. Var. hwmilis is generally found 
on soil. 
The var. major Nees is generally distributed from 
Dumfries to Caithness. It is frequent in the Lowlands and 
in the East Highlands, becoming more common towards its 
western boundary, and is common in the West Highlands. 
The want of sheltered ground makes it rare in the Hebrides. 
It is common in West Ross. It is confined to the low 
ground and to moist shady places, and is especially 
luxuriant in ravines and steep banks among coppices. 
It occasionally takes the place of the typical plant in 
some glens, but the variety usually grows among grass, 
etc., on banks, while the type is more often seen on rocks. 
Male plants are frequent, perianths less so, and fruit has 
not been seen.
