PLANTED JAVANICiE BARIOUES. 



inclined to adopt his view. His statements respecting the 

 structure of the pistillum are more liable to objection : he 

 describes the ovulum as orthotropous, having the micropyle 

 at its lower extremity, and [the embryo consequently exist- 

 ing at the same point of the seed ; my own observations, 

 which may indeed require to be verified, placing the em- 

 248] bryo at the upper extremity, or close to the insertion of 

 the seed, the ovulum being consequently anatropous. The 

 external structure of the pistillum is very singular. In an 

 early stage of the flower, immediately before or even at the 

 time of expansion, there are apparently two stigmata : of 

 these the more obvious is capitate, undivided, fleshy, but 

 not papillose, and is supported on a distinct style ; the 

 second is quite sessile, much shorter in this stage than the 

 capitate branch, and having its upper or inner surface dis- 

 tinctly stigmatic or papillose. In the next stage, the latter, 

 which I regard as the efficient stigma, gradually enlarges, 

 becoming longer than the capitate organ, which in my 

 opinion is an imperfect stigma ; and as in this stage the 

 ovarium though enlarged has not perceptibly increased in 

 diameter, this capitate stigma has the appearance of being 

 lateral. The perfect stigma, which continues to lengthen, 

 its upper surface becoming more evidently hispid or papil- 

 lose, not unfrequently remains crowning the samara even 

 when ripe ; but frequently also it is then deciduous, while 

 the imperfect capitate stigma, which has undergone no 

 change either in size or surface, more generally remains after 

 Ihe real stigma has fallen. 



In one of the flowers of a specimen preserved in spirits by 

 Dr. Wallich, and in which the corolla was wanting, and a 

 slight enlargement of ovarium had taken place, I found only 

 one ovulum, the lower extremity of which seemed in some 

 degree to support Dr. Blume's account of the position of 

 micropyle. In a second flower of the same specimen only 

 one apparently perfect ovulum existed, but the funiculus or 

 remains of a second was visible ; in the perfect ovulum a 

 more transparent point, which might possibly be micropyle, 

 was lateral ; and in a third flower, long after foecundation, 

 the samara being distinctly formed though not of its full
