Under this head we propose to describe and figure all the 
forms of Cotoneaster with which we are acquainted as_ being 
under cultivation, of the group of which C. microphylla of Wal- 
lich is the most widely-distributed and best-known representa- 
tive. Although the extremes of the series differ from one another 
widely, there is a very gradual transition between them by means 
of the intermediate gradations. We find seven plants main- 
taining, in the gardens, a distinct individuality ; and as there is 
not anywhere an account of them in print, we have thought it 
best to figure and describe all of them together, that thus their 
mutual relationship may be shown, and, their characteristics 
being defined in a form available for reference, our readers may 
be encouraged to experimentise upon the permanence of the 
forms, by raising them from seed and observing how far they 
keep their characters or what changes take place. 
All the seven plants which we are going to describe are low or 
middle-sized shrubs, with rigid dull gray or occasionally chesnut- 
coloured branches, more or less densely clothed with strong 
ascending gray hairs, which occasionally, but not usually, disap- 
pear as the branches mature. The stipules are linear, and equal 
or slightly exceed the petioles, which are half a line to a line 
long. The leaves vary in shape from oblanceolate to round, and 
are firm in texture, some quite naked above, but clothed below, 
usually permanently, with a more or less dense coating of 
adpressed white silky hairs. ‘The flowers are small, under half 
an inch across when fully expanded, and are solitary or more 
usually two to four or even six together in erect short-stalked
