 for that species. 



A Tzvo-Jieaded Daisy. — The doubHng, and even the tripHng 

 of the heads in the ox-eyed daisy {^ClirysantJienmm Leiicanthemutn) 

 and in the dandeHon {Taraxicutn Taraxiaan), and other Com- 

 positae and Chicoraceae has been often recorded. It is thought, 

 however, that the instances here figured will be of sufficient 

 "popular" interest to justify their mention in Torreya. The 

 specimens were sent me by Professor Margaret C. Ferguson, of 

 Wellesley, and clearly show three types of the double head. In 

 figure a the two heads are quite distinct on the common stalk, 

 directly opposite each other, and forced by their mutual crowding 

 to grow with the discs nearly vertical, instead of horizontal as 

 normally. In b, the two heads are more closely united, while in 

 c the fusion is complete, giving the appearance of an elongate 

 and abnormally large inflorescence. The groove in the center 

 of the disc is characteristic of such sports. In each case the 

 peduncle was fasciated throughout its entire length. These 

 double heads are not uncommon in the Rudbeckia, or yellow 

 daisy. 



Fasciation in Delphinium. — Abnormalities in the inflorescence 

 of the lark-spur are of several varieties, and much of the liter- 

 ature is cited by Penzig. One of the earlier references to the 

 subject is that of Fermond who, in his " Essai de Phyto- 

 morphie " (2: 321. Paris, 1864), described a variation in the 

 inflorescence of D. ajacis analogous to " cyclochorize polla- 

 plasique." The accompanying illustration, figure </, shows four 

 flower-clusters collected in the New York Botanical Garden in 

 the summer of 1907. At the left is a normal inflorescence, in 

 striking contrast to which are the three fasciations at the right. 

 All of the individual flowers appeared to be normal.
