fall away as a whole (see fig. 5). The receptacular paleae surrounding 
the male or disk flowers are attached at their base to a cartilaginous 
strand or rib on each side of the achene, and by using a little force in 
dissection these strands separate upwards from the base of the achene 
and from them hang the male flowers. The whole arrangement suggests 
an adaptation for distribution by wind, as the male flowers and 
their paleae at length become dry and shrivelled and would serve 
as wings; the pappus, on account of its eee would appear 
to be of little service in this respect.—J. Hurcnin
