Note on a remarkable Monstrosity in a specimen of Verbascum 

 nigrum. By H. L. de la Chaumette, Esq. 



This curious specimen was presented to me by my friend W. Coles, 

 Esq. It was gathered in a lane near Reading, in Berkshire. The 

 plant was found growing amongst many of its species. The whole of 

 the bright yellow corollas forming the spike were transformed into 

 green leaves, of the same shape as the corollas of the usual specimens. 

 The pedicels bearing these green corollas were elongated to about an 

 inch. From the centre of these corollas the pistil apparently arose, 

 as a pedicel, bearing a similar green corolla on its summit. In various 

 instances the stamens had the appearance of being converted into 

 small, undeveloped buds. This gave the whole a very remarkable ap- 

 pearance. What could have been the cause of such a change in this 

 one plant, all the others retaining their usual form of development ?
