 to be able to do so before the end of the present season.

Note on some young plants of Cardamine hirsuta, growing from 

 buds formed on the upper surface of old leaves of that plant, 

 exhibited March 3rd and 17th, 1857. By Miss Llewelyn 

 of Penllergare, near Swansea. Extracted from a Letter to 

 G. Bentham, Esq., E.L.S. 



[Read March I7th, 1857.] 



In January 1857 I observed a number of small leaves strewn 

 about on a flower-bed, some green and some purple ; on examining 

 them I found that they were all growing by means of small, white 

 fibrous roots — protruded in several places from the upper surface 

 of the leaf, which is usually turned down on the earth. In many 

 instances young leaf-stalks and smaU leaves were formed, all at- 

 tached to the parent leaf, which appears to be that of Cardamine 

 hirsuta, L. 



A large plant of this weed was destroyed in the same bed, in 

 September 1856, when leaves were broken off" and accidentally 

 scattered around. 



Since January I have observed many instances of the same leaf- 

 plants in other parts of the garden ; and in one other instance I 

 can trace the young weeds to the same cause. 



Penllergare, March 3rd, 1857. 



Memoram.d'um hy George Bentham, Esg[. 

 These very curious specimens appeared mostly to be the larger, 

 and especially the terminal, segments of the leaves of Cardamine 

 hirsuta, and the young plants were generally growing from the 

 upper surface close to the junction with the petiole, with here and 

 there a few tufts of roots from other parts of the surface ; but in 

 some specimens there were two or three young plants growing 

 from scattered points on the surface of the segment.
