100 MISSOURI BOTANICAL GARDEN BULLETIN 
is tried in the home, by placing a glass covering over the pot. 
The old spines are used to secure the detached Easter cactus 
to the stock of Pereskia. P. aculeata, from the standpoint of 
a climber, is very satisfactory, perhaps the only objection 
being its deciduous habit during the winter. This, however, 
is counterbalanced by its ornamental as well as edible fruit. 
When ripe it resembles the gooseberry and is used for mak- 
ing jelly and drinks. The branches are of a woody texture 
when mature, bearing clusters of spines about an inch long. 
The young shoots have but two short, horn-like spines which 
are slightly curved and of a dark green color. The flowers 
are pale yellow, about an inch in diameter, and hang in long 
festoons five to six feet in length. The large specimen in the 
succulent house at the Garden is so fragrant that its perfume 
penetrates into the economic house. This plant has fre- 
quently been called the climbing orange blossom. 
The variety Godseffiana possesses leaves colored crimson, 
yellow, and green upon the upper surface. When first intro- 
duced at the Garden it was planted in the experimental plot 
with a view of using it as a bedding plant in this section of 
the country. Experience showed however, that its foliage 
turned to a greenish yellow, becoming deciduous in the fall. 
When grown in a greenhouse with combined heat and mois- 
ture its tricolors are very prominent.
