MICROLEJEUNEA als 
LEJEUNEA MAcvicaRi Pears. 
This species, which is at present endemic to Scotland, has 
only been found in two sheltered ravines near the shores of 
Loch Moidart. It generally occurs on old elm-trees, but is 
also found on moist rocks. Is frequently associated 
with Le. cavifolia, L. patens, and Harpalej. ovata. The 
smooth perianths permit it to be readily distinguished in 
the field. When sterile it might be mistaken for Le). 
diversiloba or Harpalej. ovata. Perianths are common in 
spring ; fruit is frequent, and mature in April and May.

MICROLEJEUNEA ULIcINA (Zayl.) Evans 
This is the most widely distributed of our Lejewnew except 
L. cavifolia and L. patens, and extends inland from the 
west coast as far as the Trossachs. It is nowhere common, 
though frequent in many localities. Nearly always occurs 
on trees, chiefly birch, but is not confined to that tree, and 
is sometimes found on gorse, and rarely on conifers. Very 
rarely does it occur on rocks. It is less exclusively confined 
to moist, shady places than are any of the other species 
except L. cavifolia, though some degree of shelter is always 
present. It is nearly always found unmixed with the 
other species of the group, and occurs as a cluster of 
scattered stems which comparatively seldom form a layer. 
This species is very rare in the West Lowlands. Has not 
been found in the East Lowlands, nor in the East High- 
lands except near its western boundary. Is frequent in 
the West Highlands, but is rare in the exposed Hebrides. 
It has only been found in the lower part of West Ross in
