post will suit it for either pot or rock culture; but 
whether cultivated in pots or upon rockwork, it must be 
so placed that, whilst freely supplied with water at the 
roots and over the foliage (which it will require during 
the growing season), all excess of water may soon drain 
away, so that the moisture should never become stag¬ 
nant about the roots. Although the present species 
often grows in situations where it is subject to a consi¬ 
derable degree of dryness and exposure to the sun, yet 
it may, under cultivation, be grown to a much finer 
state of development if kept moist and shaded during 
its growing period. Young plants are the best to start 
with. Proceed with potting and propagating in the 
same manner as directed for former species, the fructifi¬ 
cation being ripe by August or September. 
It may be grown in-doors, although, like most of the 
other Lastraas, it usually becomes long and weak under 
confined treatment; but this may be checked if it can be 
supplied with abundance of fresh air.
