 surface of t}ie trichogyne (fig. 32), or there /nay "be a 

 short tube connecting the t..o (fig. 80). V/hether the nu- 

 cleus of the sperinatium divides at this stage, as is the 

 case in ITeinalio n (V/OLPE, '04) v/as not determined though 

 such an appearance as is presented in fig. 84 suggests tliat 

 division may occur. A sufficient numher of stages v/as not 

 obtained to enable ine to speak with certainty on the sub- 

 ject, but the stages tha,t v/ere obtained seem to render it 

 higlily probable that the nucleus from the spermatium passes 

 down the trichogyne, enters the carpogonium, and there fu- 

 ses with the nucleus of the carpogonium (figs. 82,85). 



Immediately after fertilization the trichogjTie becomes 

 much tv/isted and falls off, leaving a short stump on the 

 carpogonium (fig. 35) . Since the fusion nucleus stains 

 very heavily, the details of its structure were not made 

 out. However, because of this very capacity for taking up 

 dyes, it is easily distinguished from the other nuclei of 

 the procarp. 



Very soon after fertilization, the carpogenic branch 

 begins to be withered, and the fusion nvicleus is seen to 

 be present in the auxiliary cell (fig. 87). TJie actual 

 passage of the fusion -niicleus into tlie auxiliary cell was
