134 AROIDEA. 
The situation of the carpellum іп Ambrosinia reverts to the 
usualtype,so much so, that after the falling away of the 
antheriferous portion of the spadix, and particularly in the 
ripe fruits, there is but little to indicate that such had been 
its original structure. This inflorescence is hence some what 
analogous to instances such as Ericornis, Ananas etc. in which 
however the prolonged axis bears typical leaves. The structure 
of the seeds is highly curious, and unlike that of any others. 
I have explained it elsewhere. 
The passage to this structure is in to Dracontium, in which 
{as it belongs to the typical form of the order,) we may mee 
it to be үзе in degree. 
The fragrant matter of Calla, which has the peculiar resin- 
ous smell, is lodged in large cellular sacs, scattered apparent- 
ly without order in the Rhizoma, and are perhaps indepen- 
dent of vessels, they are easily separable; besides there isa 
general diffusion of the fragrance, but in the petioles there are 
noreservoirs. "The vernation is the same as in Ambrosinia 
but the outer lamina is carried twice round the leaf. Stomata 
are found on both surfaces, but they are most numerous on 
under.
