median formations, but they produced secondary buds in 
the axils of the segments of the perianth. These latter 
buds were themselves the subject of tertiary prolifica- 
tion of both kinds, median and axillary. The tertiary 
median growths, like the primary flower, did not 
develop median buds, but only lateral ones—quater- 
nary axillary prolification. 
The accompanying diagrams are intended to show 
the plan of arrangement in these flowers. Fig. 69 
shows the disposition of parts in the primary flower 
and the situation of the axillary buds. Fig. 70 shows

In Narcissus major a similar combination of both
