 plan it is formed in other cases.

It gives me great pleasure to name this curious plant 

 after Edwin J. Quekett, Esq. F.L.S. an excellent Botanical 

 observer, and one of our most skilful vegetable anatomists. 

 I am already indebted to that gentleman for some valuable 

 facts concerning raphides ; a plant, therefore, in which these 

 crystals form a conspicuous part of the structure, may not be 

 inappropriately selected to bear his name.

GRUNDZUGE, &c. — A new theory of Vegetable Fertilization, by Stephen 

 Endlicher. A pamphlet, Vienna, 1838. 



In consequence of the great resemblance between the 

 pollen of perfect plants, and the spores (or seeds) of crypto- 

 gamic plants, an opinion has arisen in Germany that the 

 pollen does not possess any specific fertilizing influence, as 

 has hitherto been believed, but that it is the seed of a 

 plant in its youngest condition, and that it strikes into the 

 stigma its roots, the tips of which eventuall}^ reach the ovule, 

 and there complete their evolution. Schleiden and Wydler 

 have already published their ideas upon this subject, and 

 Mr. Endlicher declares himself an advocate of the same 

 views. In the papers of the former physiologists, the 

 supposed fertilizing influence of the pollen was disposed of ; 

 but no attempt was made to shew in what the said influence 

 resides, if not in the pollen. Mr. Endlicher supplies this 

 omission by assigning that function to the papillae of the 

 stigma.
