PLANT DESCRIPTION PBT 
COMMON EXAMPLES. 
1. Strawberry (Fragara vesca). 
Calyx—Beneath the calyx is an epicalyx consisting 
of five members similar to the sepals, and presumably 
representing the stipules of the latter fused in pairs. 
Fruit (Fig. 132).—The sueeulent part is an enlarge- 
ment of the receptacle, which swells after fertilization, 
becoming a fleshy body over which are scattered the 
little achenes which form the true fruit. 
2. Blackberry (Fig. 131) and Raspberry (Rubus). 
Fruit—tThe earpels enlarge after fertilization and 
become succulent to form drupelets (little drupes). 
The fruit is really an etario of drupelets covering the 
fleshy receptacle. The calyx is persistent as in the 
strawberry. 
3. Cherry, Plum and Apricot (Fig. 132) (Prunus). 
Pistil—Monoearpous. After pollination the single 
carpel swells and a one-seeded fruit (a drupe) is 
produced. The receptacle does not enter into the forma- 
tion of this. 
4. Apple and Pear (Pyrus). 
Pistil.—Consists of five carpels. 
Fruit—After pollination the receptacle tube grows 
up round the carpels, and becoming succulent, forms 
a pome, enclosing the five carpels which go to form 
the core. 
5. Hawthorn (Crategus). 
Pistil—The pistil differs from that of the apple in 
‘consisting of only two earpels. 
Fruit—The inner portion of the receptacle sur- 
‘rounding the carpels becomes hard and forms a stony 
substance. The fruit has two stones. It is reaily 
‘formed like a pome by upgrowth of the receptacle, as 
‘may be seen by the remains of the calyx above; but, 
‘instead of a core, it has stones.
