THE EUPHORBIA. 121 



While the plants are young, nipping out the points 

 of the leading shoots is necessary to induce a full- 

 developed plant below. It is needful to continue this 

 nipping out in order to keep the plant well feathered 

 with leaf and young wood below, for on the points of 

 all fully matured young wood come the flowers. 



The pruning of the Pimelea consists in cutting back 

 all the growth that has borne flowers, pretty close to 

 the base of the young wood, as soon as the flowering is 

 over. Then thin out a little and stimulate the plant to 

 give vigorous growth, and stop the leaders once or 

 twice afterwards ; then get a moderate growth and 

 discontinue the stopping for the season, i.e. discontinue 

 it after August. 



The Inga. 



There are many varieties of this tribe, but /. Harrisii 

 is a very showy and peculiar plant. Its flowers are 

 like a flower all stamens, but displaying themselves 

 most gorgeously by expansion. They are rose-coloured, 

 but lighter in the centre. It is a cool stove plant, and 

 easy to grow, requiring only a low temperature during 

 the winter. It grows freely and produces its flowers 

 on the ripened wood of the previous year, similar to the 

 Acacia Armata. 



The pruning of this winter flowering plant consists 

 in the cutting back as soon as the flowering is over, and 

 then getting as much young wood on the plant through 

 the summer as possible, which should then be well 

 ripened before the winter. 



There are other good varieties of this genus, mostly 

 natives of the West Indies and South America. 



The Euthorbia. 



E. Jacquiniflora is about the best of this class, although 

 E. Fulgens, Splendens, and Punicea are much alike ; 

 and probably the first-named one is Fulgens, or Splen- 

 dens, so that I will select J acquivijlora for my obser- 

 vations.
