this the pistils are disposed. When at maturity these become 
changed into little drupes, grouped together upon a spongy and per- 
sistent receptacle. Bramble shrubs are sarmentose, and provided 
with prickles, with simple, alternate, digitated leaves, in threes, 
with stipules adhering to the 
petioles, and terminal or axillary 
flowers, which are rarely solitary, 
but are disposed in a panicle or 
corymb. We often meet with 
the Bramble, or properly speak- 
ing, the Rubus fruticosus, the 
Dewberry with its blue flower 
(Rubus cesius), represented in 
Fig. 421, and the Raspberry 
plant (Rubus ideus). 
In the Strawberry the calyx 
is composed o ye sepals 
joined at the base, and furnished 
with a calicule with five divi- 
sions. The stamens, which are 
numerous, are inserted upon the 
edge of a receptacle in the shape 
of a cup, which rises again at 
the base like the bottom of a bottle. The numerous unilocular 
pistils are inserted upon the lower part of the receptacle, sur- 
mounted by a lateral style. They are changed at the time 
of maturity into achenz, which, as we have already men- 
tioned, are implanted upon the receptacle, and become fleshy 
and succulent. The Strawberry plants are long-lived, grassy 
perennials, with alternate trifoliated leaves, sometimes simple 
by abortion, with stipules adhering to the petioles. The Fragaria 
vesca furnishes several wild varieties known under the name 
of Wood Strawberries ; Strawberries of all Months, Bush Stran- 
berries. The Fragaria chilensis is known under the name of the 
Pine Strawberry, the fruit of which is erect, rose-coloured, white 
within, and sometimes as large as a pigeon’s egg. The Mountain 
Strawberry (Fragaria collina) is not very common ; its frait ” 
of a lively red; ovoid, contracted at the base, almost destitute of
