I regret to have to state that the history of the plant here 

 figured is quite unknown to me. It has been cultivated in 

 the Koyal Q-arden for a good many years, flowering annually, 

 and has been seen by various collectors, none of whom 

 have recognised it. In many of its characters it resembles 

 the C. Titajaya, Jacq., of Brazil, which is merged with some 

 eight or ten garden and other species into one called C. varia- 

 bilis by PfeifFer, and I should not be at all surprised if it proved 

 to be a hybrid between that plant, which is white-flowered, 

 and some scarlet-flowered Cactus ; though it diners from C. 

 variabilis in the laxer habit, and flowering only in the even- 

 ing and night. The habit indeed is that of C. speciosissimus. 

 It flowers in July, the flower opening in the early evening 

 and remaining expanded till the following noon. 



Descr. Stems pale bright green, not glaucSus, 2 to 3 

 feet high, 3- to 4-angled, one inch and a half diameter, 

 angles much compressed, starting from near the axis, so that 

 on a transverse section the wings or angles appear as narrow
