DEVELOPMENT 
PARTS OF THE FLOWER 
PBhanogamous Plants.* 

> 
The following conclusions may be drawn from the Jonesia. 
That the axillary floral disc or growing point is quite in- 
distinguishable from the growing point of the inflorescence. 
That it is quite entire at first, and, as in all other cases, has a 
lubricate ' shiny cellular appearance. 
That the outer teguments are then pointed out by 
puncta. 
Then the anterior and posterior parts of the calyx : then 
two lateral parts, the 5th (posticous) appearing later.. 
That the stamina are then pointed out by prominences. 
Lastly, the centre of the disc is elevated into the rudiment 
of the pistillum. 
_ That the composition of the 4th or posticous sepal mature, 
is pointed out directly by the development : that it is com- 
posed of the posticous one, pointed out at the same time with 
anticous, and the 5th innermost lateral one. 
* The illustrations will appear separately, being now in course of preparation.
