St Helena. — Endemic. "Sandy Bay, in couvalle Broadgut dicta, rarissima" — 

 Burchell, 65. 



As Burchell states, this plant has much more the appearance of a Tournefortia than a 

 Heliotropium, but although the flowers of the only specimen in Kew Herbarium are 

 almost wholly destroyed by insects, we have been able to confirm his description of the 

 ovary. There is a figure of the plant among Burchell' s unpublished drawings at Kew. 



It would seem to be one of the eudemic plants that have become extinct, yet no 

 description of it has previously been published.

 where — Meliiss. 



One of the most universally spread plants in tropical and subtropical regions, and also 

 in some temperate countries. From Burchell's manuscript we learn that this plant was 

 common in the interior of the island during his time, and Meliiss expresses an opinion that 

 it is probably a native.

" Sea-bean." 



Almost everywhere on tropical and subtropical sea-shores, and also penetrating far 

 inland in some countries. Meliiss takes up the name Convolvulus brasilieiisis, from Box- 

 burgh, but he does not appear to have met with the plant, which is rather singular, because 

 it is one of those plants which are not easily displaced when they once obtain a footing.
