to consist of a production of the stigmatic or placental tissue | 
* beyond the open end of the convolute leaf, which in this 
case is united throughout nearly its whole lengt h. 
What is the reason why in all this tribe, the stalk of the 
ovarium is obliquely inserted in the disk and with regard to 
the axis ? In this, the obliquity is towards the ventral suture. 
Can the anatropism of the ovula have any thing to do 
with the rectembriate embryos ? 
The stigmatic canal is choked up with tissue and sur- 
rounded by a ring of vessels, derived from several fasciculi 
crescently arranged at each suture, the sides of the ovary ap- 
. pear to be cellular, its superficies has crowds of ae at 
right angles. 
"Most of the pollen is incomplete, water causes s the protrusi- 
on of fovilla, which on the application of iodine often appears 
like an extremely long highly convoluted gut, but not S0. 
membranous as Whois tubes produced in other plants by 
stigmatic action. It appears to have two coats, both very 
thin, the outer usually like the inner, with 3-5 pores. 
A longit. section of the calyx tube, shewsa green superfi- 
cies with which the sepals are continuous, the rest from which 
all the genitalia and petals proceed, is white. 
The vascular supplies pass up between these two, having 
previously sent off long branches to the stalk of the ovary ; 
is not this a proof, that the sepals really commence at their 
articulations ? the so called tube being an excavation of the 
apex of the axis, 
The venation presents nothing peculiar, but is far from 
being as mentioned by anthors, faint. of 
There is a sort of obliquity apparently in the insertion :

is innermost, the reverse of the usual position in the family £ — 
Were it not for this, it might be considered as the first step ae
