OF THE OVULES. 265 
In a species of T'riwmfetta (see p. 260), of which I 
examined dried specimens, the 
ovary was open and partly folia- 
ceous; it bore on its imfolded 
margins ten erect leaflets, repre- 
senting so many ovules; each 
leaflet was conduplicate, the back 
being turned towards the pla- 
centa. 
On the other hand, there are 
cases in which the leafy coat of 
the ovule, in place of being a 
distinct organ, seems to originate 
from the margin of the carpel- 
lary leaf itself—to be, as it were, 
a lobule or small process of the 
carpel, and not an absolutely 
new growth. Thus, Planchon,' 
from an examination of some 
monstrous flowers of Drosera in- 
termedia, was led to the inference yg, 141 —Leafy ovules,

leaves. This acute botanist was
