Garden. XIX. p. 25—33. pl. 1—9. March 4, 1908.) 
An account of the frequent early epiphytism, and later independent 
growth of Ficus aurea and F. populnea. In these Urostigma species 
typical gall-flowers are not found, though two kinds of pistillate 
flowers are seen. The seeds of F. aurea are shown not to germinate 
in the dark, but those of F. populnea do not possess an equal need 
of light for their germination. Trelease.

The floras of both these counties have been studied with 
fruitful results, which have been published in various papers by 
Bennett, Druce, Grant, Hanbury, Marshall and others within 
recent years, yet in this account of the results of a botanical visit 
in July 1907 there are numerous additions to the published records 
for both East Sutherland and West Sutherland, most of these 
are critical forms, whether regarded as species or as varieties; and 
a few (e. g. Viola canina L., var. calcarea , Reichb., and V. tricolor , L., 
vav. vivariensis Jord.) have not been previously put on record from 
Scotland. J. W. A. Trail.
