In one line of descent there was а marked deviation from this 
habit of seasonal growth which was very striking in that an entire 
series of sister plants in 1916 exhibited this deviation. After the 
branches that usually develop were through blooming, young and 
new branches appeared from the axils of many of the rosette 
leaves (which had died) ; these continued to grow, making a bushy 
compact second growth quite distinct from the earlier growth both 
as to time of development and to position on the plant. This habit 
of growth is shown in TEXT-FIGURE I. 
with the growth of both periods shown; the older dead branches 
of the first period extend above the newer growth. То the left 
the old growth has been cut away, leaving only the branches of 
the second period. Between the close of the blooming of the 
first growth and the beginning of bloom on the second growth 
there was usually an interval of several days.

growth for a single plant ((4 X Ex) —9-5-12 —no. 6} are pre-
