Plectocomia elongata is the Malayan bamboo with hooks, closely allied to Calamus of which Hooker has seen erect species with hooks. He says some very erect Acacias have immense hooks. Andersson speaking of some of the Acacias called "Wait-a-bit" by the Dutch says each hook will on average bear weight of 7 lb. Lake Ngami 1856 p. 152. But Hooker gives me a better instance of Tasmanian Drosera,

which uses glands to climb. Drosera close to Dionæa

Lindley Vegetable Kingdom says p 433 Drosera binata has viscid leaves with glandules, fringes which close upon flies - this leads in to Dionæa.
