104 ALTERATION OF POSITION. 



vescttf each of which had a tuft of small leaves at their 

 extremity. In the common marigold and in Zotus 

 comlculatus I have also seen instances of this kind. 

 Kirschleger^ describes a tuft of leaves as occurring on 

 the apex of the flowering spike after the maturation of 

 the fruit in PlmdaQo^ and a similar growth frequently 

 takes place in the common wallflower, in Antirrhinunb 

 majuSy &c. In cases where a renewal of growth 

 in the axis of inflorescence has taken place after 

 the ripening of the fruit, the French botanists use the 

 term recrudescence, hut the growth in question by no 

 means always occurs after the ripening of the fruit, 

 but frequently before. Professor Braun cites the case 

 of a specimen of FJantago lanceolata, in which the 

 spike was surmounted by a tuft of leaves and roots, as 

 well as a still more singular instance in Enjngmm vim- 

 parum, in which not only did particular branches ter- 

 minate in rosettes of leaves provided with roots, but 

 similar growths proceeded from the heads of flowers 

 themselves. Baron de Melicoq^ gives a case in 

 Primula variabilis , in which at the top of the flower- 

 stalk, in the centre of six flowers, was placed a complete 

 plant in miniature, having three leaves, from the axil 

 of one of which proceeded a rudimentary flower. Mr. 

 W. B. Jeffries also forwarded me a polyanthus (fig. 52) 

 in which the peduncle was surmounted by a small plant, 

 forming a crown above the ordinary flower-stalk, just 

 as the crown of the pineapple surmounts that fruit. A 

 similar instance was exhibited at the Scientific Com- 

 mittee of the Horticultural Society on July 11th, 1868, 

 by Mr. Wilson Saunders ; the species in this case was 

 P. cortusoides. To Mr. R. Dean I am indebted for a 

 similar proliferous cyclamen, which seems similar to 

 one mentioned by Schlechtendal.' This author alludes 

 to an analogous circumstance in the inflorescence of 

 Cytisns nigricans^ where, however, the change was not
