DR. B. SEEMANN ON THE CRESCENTIACE^. 15 



sary, as tlie " Jaroba'' of Marcgrav, from which the older specific name was borrowed, is 

 not, as Swartz supposed, a synonym of this plant, but, judging from the indifferent de- 

 scription and the i*ude woodcut, a Cucurbitacea'^ . T. parasiticum is a very characteristic 

 species (the only one hitherto introduced in our gardens), which has fortunately no con- 

 flicting synonymy. T. Ulacinmn was originally founded by me, upon Miquel's Schlegelia 

 lilac'inu, adding as synonyms Schlegelia elongata of the same author, and the doubtful 

 Besler'ia ? violacea and B. ? ccendea of Aublet, original specimens of which are preserved 

 at the British Museum. Recently I discovered that the plant described by Linnaeus in 

 his ' Plantse Surinamenses ' as Citharexylon cinereuni (five specimens of which are pre- 

 served under that name in Linnseus'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 Citharexylon cinereum of the ' Systema,' which was 

 taken up, it would seem, from Jacquin's, Plumier's, and Pluckenet's figures, and is a 

 terrestrial tree inhabiting the A¥est Indies, to which the brief character {^'^ parasiticnm, 

 scandens") of the 'Plant. Sm'inam.' cannot possibly apply.

There are no specimens of this plant preserved in Linnaeus' s herbarium; and Linnaeus 

 seems to have taken it up solely from Plumier's figures.

* The description inMarcg. Hist. Reg. Nat. Brasil. lib. i. p. 25, runs as follows : — " Jarola Brasiliensibus dicta, Va- 

 saca amargosa Lusitanis. — Altissimas arbores beec planta asceudit, caule lento, tereti, qui hinc inde in longis pedi- 

 culis tria folia opposita habet Phaseoli modo, sunt autem plane similia foliis JNIucuna. Fructus autem similis fructui 

 Cuete, sed ut plurimum minor, eadem pulpa, iisdem seminibus, ejusdem quoque usus." — Marcgr. Hist. Reg. Kat. 

 Brasil. lib. i. p. 25. The figure represents a climbing stem, with alternate, tripartite or trifoliolated leaves, and obo- 

 vate, dotted fruits.
