Cucumber tree: "a favourite perch for three or four of the white vultures which swarm in the island, and the picture formed by these ungainly birds on top of this ungainly tree is an odd one." (T. Bent, p. 380)

Comments
Socotra cucumber tree environmentalism, looks and products appeal to me.
Wildlife gardens also catch my consideration.
Wouldn't it be aesthetic, ecological, tasty and useful to work Socotran cucumber trees -- with their companion plants Cissus subaphylla and Lyceum sokotranum -- into an indoor or outdoor garden?
