Lokoja, Old Calabar. 



A climber 20 ft. or so long, with remarkable flowers — greenish 

 with red purple ribs outside, brow^nish and yellow -mottled inside. 

 This plant has flowered on several occasions since its introduc- 

 tion to Kew about 1867, when it has been of considerable interest 

 to the visitors. 



All of the above are more or less ornamental ; otherwise they 

 are of no special value ; but it may be of interest to note that 

 the use given for the root of A, bracteata in Sudan is also said 

 to be of vpJue for the same purpose in India (Treas. Bot.) and 

 the " Virginian Snake Root " {A, serpentaria^ Linn.) of the 

 United States, used as a stimulant tonic had at one time a 

 similar reputation (Mus. Guide).
