other phytologists, that these pretended offshoots from the pol- 

 len globules penetrate through the stigma and style into the 

 ovary, notwithstanding the great importance I attribute to other 

 observations of many of these naturalists. 



" The following are the results of the numerous investiga- 

 tions which I have made on this phenomenon for the last three 

 years : As soon as the pollen globules have discharged their 

 contents upon the stigma, and fructification is accomplished, the 

 papillae of the stigma begin to separate from each other. The 

 papillae are terminated by a bundle of long capillary fibres, 

 passing from the ovary through the style to reach the stigma. 

 These fibres are always accompanied by elongated cylindrical 

 cells, and usually, but not in the grasses, by spiral vessels ; and 

 are distinguished from the sap fibres by their greater length and 

 delicacy. Frequently, the ends of the filaments which proceed 

 from the pollen globules are attached to the ends of these capil- 

 lary fibres, between the papillae of the stigma, in such a manner, 

 that the filaments seem to be continued into the fibres ; and the 

 connexion appears to be the principal cause which has given rise to 

 the opinion already noticed. But we find many filaments connect- 

 ed with the papillae by means of the viscid secretion of the stigma, 

 as well as with the fibres. This viscid secretion also frequent- 

 ly contracts, particularly on the withering stigma, into long thin 

 filaments, which swell up in water. Many of the fibres become 

 distended at this period, and contain a dark matter, frequently 

 connected with the pollen globules, and resembling the substance 

 found in the latter. But I have observed a similar distention in 

 the fibres of the style, and a similar substance in these fibres, as 

 well as in the cells of the style and stigma of flowers that had 

 not been fructified. 



" Another circumstance also which may, and very probably 

 has given rise to deception in this matter, is this : in some 

 plants the papillae of the stigma are of a globular shape, and 

 immediately connected with the fibres before described. In 

 others we find, under the cells of which the stigma is composed, 

 globular cells, in which the fibres of the style terminate. Tne 

 former is the case in the Hypericum perforatum, the latter in 

 the Cypripedium calceolus. When the stigma and style in these 

 plants have dropped off, the round cell?, with the fibres attached
