become entirely bulbil-bearing, cultivation aids the process. 

 What efiect, however, cultivation would have on the purely 

 flower-bearing variety, or that with both bulbils and flowers, 

 is a matter to be settled by experiment. 



In the inflorescence of this Allium there are two propaga- 

 tive agencies in oscillation. The result in one direction is 

 the normal production of flower and seed, in the other the 

 production of bulbils, representations in miniature of the 

 parent bulb underground. 



The cultivated bulb is about thrice the size of that in the 

 wild form. In November, when new leaves of the plants on 

 the wall were 5 inches in length, those in the garden were 

 2 feet. The roots of the latter, however, were shorter than 

 those of the former. 



Postscri'pt. — Since the above was communicated to the 

 Society, Professor Bayley Balfour has directed my attention 

 to a note by M. Clos * referring to the subject of the 

 rupture of the peduncle. He found examples at Fontainbleau 

 and Toulouse having trilobed capitula of bulbils only, each 

 capitulum borne on a split branch of the scape. He regards 

 the tripartition as accidental.
