Hemeroeallis fulva, L., some Anomalies in the Flower of. 



By E. Geneau. I. (Bcv. gen. Bot. xiii. p. 337, 1901 ; figs. 54-69).— The 

 abnormalities are almost confined to the lower part of the inflorescence, 

 and consist partly of more or less complete abortion of the sepals and 

 stamens, and of the transformation of the petals into stamens. More 

 frequent are cases of concrescence either of the constituents of single 

 whorls, or of those of different ones. A comparison is suggested 

 between the normal flowers of Scitaminece and these abnormalities 

 exhibited by Hemeroeallis. — J. B. F.
