Orver XLVI.—LYTHRARIE:. 
Trees, shrubs, or herbs of variable habit with the branches 
often tetragonal. Leaves usually opposite, exstipulate. Calyx- 
lobes valvate. Petals usu- 
ally crumpled. Stamens 
definite or rarely numerous. 
Fruit usually free from the 
calyx-tube. This order 
comprises several very 
curious genera, including 
the Pomegranate (Pinica 
Granatum), referred here 
by some botanists. It is 
remarkable for the apple- 
like fruit having two series 
of carpels one above the 
other. Formerly, this was 
more generally cultivated 
in boxes or large pots for 
standing out in the Summer 
time. The flowers are usu- 
ally scarlet, but there is a 
white and also a yellow 
variety, and also a double 
flowered form as depicted in Fig. 103. Punica Granatum flore pleno,
