ANALYTICAL TABLE OF FLOWERING PLANTS: HEIGHT AND 



MODE OF BRANCHING 



I. Of the same or nearly the same height (1 5 — 

 1.8 m). 



A. Flowering over in October. Stem erect, 

 rigid 



1. Of the same strength. 



a) Secondary stems strong, branches 



short, foliage lax (Fig. 55) ... 1. O. Lamar ckiana. 



b) Secondary stems weak, main 

 stem branched; infrutescence lax; 

 stem reddish, brittle, often wavy 



(Fig. 49, 67, 69, 70) 2. O . rubrinervis . 



2. A little weaker. 



a) Leaves narrow, very much like

b) Leaves broad, like O. lata but 



taller 4. O.semilata. 



3. Very strong, stem stout and very 

 erect, dense foliage, short internodes, 

 branches short and rosette-like. In- 

 florescence closer and fuller ... 5. O.gigas. 



B. Flowering continues till winter. Weak 

 and drooping at that time. 



1. Much branched; flowers many; group 



of buds above the flowers small . . 6. O.btevistylis.

 group of buds above the flowers 



very long 7. O.leptocarpa. 



IL Shorter (about a meter or less). 

 A. Much branched.
