ADENOCALYMNA comosum. De Cand. Prodr. v. 9. p. 201. BIGNONIA Comosa. Cham. in Linnæa t. 832. p. 693. A highly natural group of the old and very extensive Genus Bignonia, inhabiting Brazil and Guiana, distinguished by their scandent scabrous stems, ternate leaves, (or geminate with a simple cirrhus, in lieu of a terminal leaflet), and racemes of large, handsome, generally yellow, trumpet-shaped flowers, glabrous or pulverulento-tomentose, with large deciduous bracteas and smaller bracteoles; the leaves, bracts, and calyces beset with conspicuous pateriform dark-coloured glands. These constitute the Genus Adenocalymna of Martius, adopted by De Candolle, and so named from any, a gland; kávμpa, a covering. It must be confessed that the species, nineteen in number, are difficult to be defined FEBRUARY 1ST, 1846. x 2 • Thrifty Whiskers by words, and we should have failed to determine our present plant (sent from Rio to the Royal Gardens, by J. Lynd, Esq., in 1841), were it not that we possess an authentic specimen of A. comosum from Chamisso. The A. longibracteatum, Mart., is con- sidered by De Candolle to be scarcely distinct from this. Our plant is a beautiful climber, and trained to the rafter of a stove makes a fine appearance with its copious flower-buds, which look like large clusters of hops in September and October, and as soon as the bracteas fall, the conspicuous yellow flowers burst forth. The species is increased by cuttings.

Botanical Description A tall climber, with fruticose, punctato-scabrous stems

and opposite ovate leaves, sometimes approaching to a lanceolate figure; the petiolules incrassated at their apex. Racemes both axillary and terminal, at first so densely clothed with large con- cave bracteas as to look like the large aments of the Hop; these fall away before the corollas expand, except two lesser bracts upon each pedicel, but which, still, are larger than the calyx, and event- ually fall away also. Calyx tubulose, five-toothed, with about five large glands below the teeth, similar to those on the leaves and bracts. Corolla large, handsome, bright yellow, trumpet-shaped, the limb very large, spreading, two-lipped, upper lip of two, lower of three, large, rounded, waved lobes. Stamens and style, with the two-lipped stigma, included.
