(Fig. 218) is shaped like an egg. Its hilum is diametrically 
' opposite to the microphyle. This kind of ovule is called orthotropal. 
In the Hellebore, on the contrary, the ovule has its point of 
attachment placed near the microphyle, and we notice a cord-like 
swelling on one of its sides, which reaches all along it, and is called 
raphe (Fig. 219). This kind of ovule is called anatropal. 
In the French Bean the ovule has in the same way its point of

attachment placed near the microphyle, but as it has no raphe and 
is bent, it is said to be campylotropal (Fig. 220). 
Such are three principal forms of the ovule. The second is the 
most common, and the first is the most rare. 
Tue REcEPrACLE. 
The calyx, corolla, stamens, and pistils, are inserted in the ex- 
tremity of the floral peduncle, which is called the receptacle. Its 
form is very variable. In the Ranun- 
culus it is conical; the calyx, corolla, 
stamens, and pistil are inserted and 
ranked in succession on its sides, the 
last organs nearly at its summit. In 
_ the Myosurus (Fig. 221), it is so much 
" lengthened, that it resembles a 8 
spike, of which the flowers would

the stamens are inserted underneath 
the pistils, these stamens are said to be
