13, Long section, double of pistillum, shews iie the dispo- 
sition of the vessels. 
14. Ovulum. Iam not quite certain as to its not having a 
second coat. 
Has. Pannukka Bootan. 
"This presents to my mind the maximum of opposition, the . 
three outer series being strictly opposed, and if the angles 
of the cup be supposed to arise from, or point out the 
| union of the barren stamina, tbe 4th series will likewise 
: be opposite. But I prefer considering the angles as indi- 
cating the situation which the additional stamina would 
occupy, if developed. 
This cup is evascular, and I may here remark that vascu- 
larity of organs depends entirely on the degree of deve- 
lopment, hence stamina, when barren, to have vessels, must 
passed a certain point in their development. 
The anthers are curious, they open internally along the 
furrow separating the loculi, by separation of the edge 
of the valve from the connective hence no inner valve exists, 
as in almost all other cases. 
Moisture causes the valve to return to its original 
direction, dryness causes its reflexion. The anther is alto- 
gether analogous to a single locellus of a bilocular bilocel- 
late anther. Are we to imagine the total suppression of 
the inner yalves,a tendency to which exists in some 
Hamamelidez, or are we to imagine the internal union of 
the margins of the locelli, as the cause of this curious 
anomaly. 
In the earliest stages in which I have been able to exa- 
"Wine it, the formation of the anthers remains the same. 
.. Hence even among typical anthers, two modifications 
"Té to be found, bilocular bilocellate anthers, resulting from 
the development of two leaves, and bilocular unilocellate, 
resulting from that of a single leaf. A distinction should 
p be drawn between these cases, the latter being.
