the manuscript name of Dennesiana, adapted from that of 

 Mr. G. B. Dennes, who was Honorary Secretary of the 

 Botanical Society of London at the time when some speci- 

 mens were sent by Mr. Hunt for distribution through that 

 Exchange Club. Mr. Watson's treatment of the plant was 

 to protect the seedlings in a frame in winter, and put the 

 grown up plants into the open garden ground in the 

 following summer to flower and seed. The severe frost of 

 May, 1867, in Surrey, proved almost fatal to the small stock 

 of plants that he possessed; he, however, took up the roots 

 and repotted them, when one alone flowered in the dry 

 summer of 1868 in a weakly condition. This he hoped 

 might be available for the Botanical Magazine, but he was 

 disappointed, and it is only after twenty more years that 

 an opportunity has occurred of carrying out Mr. Watson's 

 intention of having this very interesting plant figured in 

 the Magazine. The changes in the colour of the flower 

 are, as that author states, remarkable ; the early buds are 

 of a fine purple, but as they expand they become of a dull 

 slate colour passing on to a dingy fawn and when dry a 

 sort of russet brown. 



The source of the specimen here figured is a plant found 

 in Mr. Watson's garden, after that lamented botanist's 

 death, by Mr. Nicholson of the Royal Gardens, Kew, and 

 which he brought to Kew. This flowered in tho herba- 

 ceous pit in the end of May. — /. D. H.
