instrumental in producing various remarkable hybrids among which may be 
cited the following : — 
C. x Lawrebel, which has been figured in the Lindenia, was raised in 
Sir Trevor Lawrence's collection. | 
C. x concolawre, to which the same observations apply. 
‘C. Xx gigas, by crossing with C. x Harrisianum. 
C. x enfieldense, by crossing with C. Hookerae. 
C. x Antigone, by crossing with C. niveum. 
C. x Cobbianum, by crossing with C. x Salliert. 
C. x euryale, by crossing with C. superbiens. 
C. x Henry Graves, by crossing with C. x Marshallianum. 
C. x Lawrenceo-Regnieri BLev, of which a portrait appeared in the preceding 
volume. 
C. x Numa, by crossing with C. Stoner, etc. 
This progeny has been propagated, and many of the hybrids mentioned 
above have themselves produced other seedlings some of which are of great 
promise, notably C. x Fames Buckingham, which has been derived from 
_ C. X enfieldense. 
From a cultural point of view C. Lawrenceanum is one of the most robust 
and vigorous of the warm species. It is advisable to repot it almost every year 
owing to the rapidity of its development. During the growing period too much 
water cannot be given, and the compost should be always moist. After growth 
has been matured the amount of water may be diminished for three or four 
weeks.
