the most numerous. In the first case the divisions mostly take 
place after the contraction of the leafit, which in the bud marks 
the termination of the petals; orif it occur in the lower and 
broader part, it carries the appearance of a division not of an 
offset, being wide at the hase and contracted upwards ; whereas 
the legitimate offset is uniformly contracted at the base and ex- 
panded upwards, except in the few instances where it is capillary. 
In the second case the receptacle is generally small, and the leaves 
are expanded towards the apex. In both the receptacle is but 
little contracted at the summit, and assumes somewhat of a tur- 
binate form ; but the best security for the student will be to ex- 
amine many examples, and to judge by comparison of their pro- 
per form. | | 
. Another word, which perhaps may require some explanation,— 
rather, however, from a peculiarity in the mode of growthin this ge- 
nus than from any singularity in the use of the term,—is Su ncurvs. 
In many roses, perhaps in some degree in all, two appearances 
may be observed ; and, if I may be allowed the expression, every 
species under different circumstances has two distinct habits. A 
seedling Rose of the family of R. canina, for instance, where this 
. property is very remarkable, usually comes up a small and feeble 
plant; it soon puts forth branches, weak like the parent from 
which they spring. ‘he aculei are few, small, weak, and but 
slightly hooked ; the flowers pale and solitary ; or, if in a favour- 
able soil, two or even three flowers may be seen together; and the 
plant for several years probably will not exceed the height of four 
or five feet. If in this state it be cut down, a strong shoot pro- 
ceeds from the root or from the base of the stem, which in one 
year will rise eight or ten feet in height, armed with abundance 
of strong hooked prickles, whose base is nearly equal to their 
: | length ;
