Results. 
That the tendril is especially part of the merus 
and that it is developed from the axillary floral disc. 
'That the leaf puncta appear before the stipular puncta, 
and that these seem to belong to the leaf in ab origine. 
'That the leaf punctum is first entire; that the lobes are 
lined out when the leaf is entirely cellular; that the stipula 
are entire originally, and indeed up to a latish date. 
That the bractez are indicated by successive puncta. 
'That the vessels of the veins of the leaf are developed 
first in the midrib, then in the veins next to it, thence to the 
margin; that their course is first indicated by transparent 
lines, then the vessels appear, sometimes it would seem 
independently, i. e., not extended from previous ones.
