(13) Considering the succulence of the plants, their power of 

 recover}^ from the effect of low temperatures is remarkable. Large 

 limbs which hang limp beside the plants will often regain their 

 normal position upon the advent of growing weather, provided they 

 are not disturbed while the weather is cold. 



(14) Color characterizations both in flowers and plant body are 

 very deceptive, changing as the day advances in the former and 

 changing with temperature, moisture, health, or disease in the latter. 



(15) Proliferation of fruit is not necessarily a specific character- 

 istic but may be brought on by extraneous conditions. If this habit 

 could be induced in the economic forms their value for forage would 

 be decidedly increased. 



(16) In all of the larger species especially, the plants grown from 

 cuttings and those grown from seed present a very different appear- 

 ance ; the latter are treelike and the former are headed on the ground 

 without distinct stems.
