Mr. Watson informs me that the D. triyetaloides and D. 

 racemosa are very easily cultivated at Kew, where D. 

 grandiflora is almost a failure ; as also that Messrs. Veitch 

 have raised seedlings from crossing it with D. grandiflora, 

 as they also have from crossing D. racemosa with grandi- 

 flora, the latter cross being named D. Veitchii. 



There remains only to add that D. tripetaloides is a 

 native of the Southern and Eastern districts of the Cape 

 Colony, from a little East of Table Bay to the Southern 

 districts of the Natal Colony, growing with D. xenosa on 

 marshy ground. It was introduced into cultivation by Mr. 

 James O'Brien, of Harrow-on-the-Hill ; it is a fleshy-rooted 

 plant of as easy cultivation and propagation by stoves as a 

 Primrose. The specimens figured flowered in a cool house 

 in the Eoyal Gardens. The plant is very hardy, having 

 been frozen hard in a cold frame without injury. Its 

 flowering season lasts for three months. — J. D. H.
