lobes, of which there is no trace in C. crispata. Mr. Lynch 
informs us that C. Thorncroftii requires tlie usual treatment 
under ordinary tropical conditions of the other species of the 
genus except that in winter it appears to demand a rather 
higher temperature than the majority, and to prefer a 
greater degree of dryness. It has done well in the Stove, 
but has not succeeded in the Cactus House. The masses of 
fleshy roots appear to be sensitive to any excess of moisture, 
especially if associated with too low a temperature.
