The Jmpatiens which forms the subject of our illustration 
is a native of New Guinea. The plant from which the 
material for this figure has been derived was raised at Kew 
from a cutting sent from the Royal Botanic Garden, Glas- 
nevin, and raised there, so Sir F. W. Moore informs us, from 
seeds sent by Dr. R. Schlechter from German New Guinea. 
It has proved a freely growing, freely flowering species, 
amenable to very varied cultural conditions. It has survived 
the winter and flowered well in the cool moisture of an 
Odontoglossum house, with a night temperature of 50° F.; 
in the dry atmosphere of a Cactus house; and in a bright 
stove pit with a night temperature of 65° F. But of these 
three conditions that most suitable is clearly the last men- 
tioned ; the plant grows more freely, flowers more profusely 
and is of a decidedly brighter colour when grown in a 
stove pit. It requires a rich soil and can be readily pro- 
pagated by cuttings. The nearest ally of J. LHerzogi is 
SepTemBer, 1911.
