Mr. Watson, the Assistant-Curator of the Royal Gardens, 

 who brought seeds of this beautiful plant from near King 

 William's Town in South Africa, in 1887, informs me that 

 it grows in masses in marsh-lands, the stems supporting 

 one another, and the whole forming a beautiful picture, 

 suggestive of a group of Campanulas. The species 

 appears to be a widely diffused one in South Africa, ex- 

 tending from the Transvaal westwards to the Orange Free 

 State, and southward to Plettenburg Bay. In the Natal 

 mountains it ascends to six thousand feet (Sutherland). 

 It is described by Sonder as a rigid annual, but Mr. Watson 

 found that it had a tuberous rootstock. From its habit it 

 is well adapted for pot culture as a hanging plant ; the 

 branches descending on all sides, with ascending tips 

 loaded with bright blue flowers. The specimen figured 

 flowered in a cool house of the Royal Gardens in June, 



May 1m, 1891.
