lished species, ii. New or imperfectly known species. The 
genus /S 'cotanthus is based on the Bryonia cochin-chinensis, Lour. 
Melangium and Abobra are new genera, founded on So. American 
plants. M. Naudin proposes, the following provisional sections of 
the order Cucurbitaceae, excluding Zanonia , Nhandiroba , and 
Feuillea , which require further examination, and may prove types 
of distinct groups. 
1. Cucumerineae. —Ovary bi-trilocular (or rather with 2 or 3 
placentas); ovules and seeds transverse, usually indefinite. 
2. Cydanthereae. —Ovary with a single placenta (although 
possibly tricarpellary); ovules inserted transversely, or 
slightly oblique. 
3. Abobreae. —Ovary tricarpellary (or perhaps also of fewer 
carpels) ; ovules usually definite and erect. 
4. Sicyo'ideae. —Ovary 1-2-3-carpellary. Ovules definite, 
usually solitary and suspended. 
Neumann, L.—Note sur la culture et la Grefie des Luculia. Adans. 
ii. p. 198. Neumann is attempting to graft Luculia (Bubiaceae) 
upon certain genera of Caprifoliaceae. His experiments are not 
decisive. The grafts succeeded upon Rogiera. Observations are 
added upon the distinctions between Bubiaceae and Caprifoliaceae.
