PROLIFERATION.

veloped beyond the flower, of very considerable length 

 and bearing simple leaves, each of the same size as the 

 leaflets of a normal leaf. PI. XXX, fig. 1, also shows a 

 similar case in which the shoot terminates in a flower. 

 Mr. T. A. Dymes supplied a plant of Trifolium rep ens 

 which bore a virescent head in which each flower was 

 transformed into a long-stalked vegetative shoot bear- 

 ing two or three often imperfect leaves (composed of 

 one or two leaflets only). 



Some " flowers " of Cephalotaxus, each of which 

 usually forms two ovules only, had, instead of forming 

 these, developed into a leafy bud. 



In the carnation, as a result often of hybridization, 

 the flowers of the inflorescence all proliferate into 

 spike-like, green, bracteose branches ; this is the form 

 known as the " wheatear " carnation ; the same thing 

 occurs in some of the other species of DiantJnis (PI. 

 XXIX, figs. 2 and 3), and also in the garden-pea. 



In the pear the vegetative impulse, which produces 

 the proliferations already described, may proceed still 

 further, and the fruit or fruits may terminate in a 

 leafy, vegetative shoot (PI. XXIX ? fig. 4). 



In Scabiosa atrupurpurea the terminal floret (PI. XXX, 

 figs. 2 and 3) of the capitulum was seen proliferating. 

 In the specimens of Selaginella grand is, already in part 

 described, many of the cones had proliferated into leafy 

 shoots; these cones had been growing against the moist 

 sides of the Wardian case. Goebel describes a similar 

 instance. 



Ridley observed a very interesting case in Equisetum 

 maximum , where the cone had proliferated into a vege- 

 tative shoot, a phenomenon which had been observed 

 by other botanists before him. 



Axillary Proliferation. 



This may be either reproductive or vegetative. 

 Instances of the former will first be cited, beginning 

 with those in the axils of bracts. Chifflot cites a cone
