generally found that in monopodial types, e.g., Nurma ( 
arboreum, Linn.), Broach (@. herbaceum, Linn.), the vegetative 
period, before the flowers begin to appear, is considerably 
longer than in the sympodial types, e.g., Bengals (G. neglectum, 
Tod.). This lengthening of the vegetative period is illustrated 
in Table ITI.

character behaves when parents exhibiting the extreme types

kind, is obtained a series in which every stage from early to late

dial forms tend to group themselves at one end of the series and 
e sympodial forms at the other. Accuracy of expression is 
difficult to obtain in this matter owing to the impossibility of 
expressing, except in the most general terms, the proportion 
which exists between the number of monopodial and sympodial 
branches on a particular plant. Table IV is, however, an 
attempt to arrive at such an expression. The plants, in both 
cases belonging to the F, generation, are arranged in four 
groups—(1) monopodial type, (2) approximately three-quarters 
of the secondary branches monopodial, (3) approximately one- 
half of these branches monopodial, (4) sympodial type ; an values 
are given to these groups which represent as nearly as possible
