sary, as the « Jaroba" of Alarcgrav, from which the older specific name was borrowed, is 
not, as Swartz supposed, a synonym of this plant, hut, judging from the indifferent de- 
scription and the rude woodcut, a Cucurbitacea*. T. partmHcum is a very characteristic 
species (the only one hitherto introduced in our gardens), which has fortunately no con- 
flicting synonymy. T. Ulaciniim was originally founded by me, upon Miquel's Sehlegelw 
Marina, adding as synonyms ScMegelia elongata of the same author, and the doubtful 
Beslerha ? vlolacea and B. ? car idea of Aublct, original specimens of which are preserved 
at the British Museum. Recently I discovered that the plant described by Linnseus in 
his ' Plantae Surinamenses ' as QUharexylon cinereum (five specimens of which are pre- 
served under that name in Linnams's own Herbarium) must also be referred to this 
species. Sir J. E. Smith had already noticed, in a memorandum to the Linnean specimens, 
that they could not belong to the OUharexylon cinereum of the ■ Systema,' which was 
taken up, it would seem, from Jacquin's, Plumier's, and Pluckcnet's figures, and is a 
terrestrial tree inhabiting the West Indies, to which the brief character (" parattticum, 
scandens") of the 'Plant. Surinam.' cannot possibly apply.

There are no specimens of this plant preserved in Linnams's herbarium ; and Linnseus 
seems to have taken it up solely from Plumier's figures.
