 when the sun shines upon them, and close at sunset. The soil 

 best suited for these plants is a mixture of light loam, peat, 

 and leaf mould, in about equal proportions. They are well 

 adapted for training upon pillars or for trellis-work in the 

 stove. The annual species belonging to this genus require 

 sowing in gentle heat in spring ; the perennial kinds may be
