Hab. Between San Bias and Tepic.—St Hilaire has endeavoured to show.an affinity between this plant
and the Onagrarioe. But it is surely more nearly allied to Cucurbitacece and Loasece, Professor Lindley
places it in this latter Order without any mark of doubt, though it differs from it in the definite stamens and
solitary pendent seed. There is an excellent figure of the entire plant in Jacquin’s “ leones Plantarum
Rariores” above quoted.—The flowers and fruit are nowhere accurately figured. The calyx is coloured,
large, funnel-shaped, pubesceuti-scabrous, divided half-way down into five broadly lanceolate erecto-patent
acute segments; at the base (which is incorporated with the ovary) are five, projecting, obtuse, deeurrent teeth,
alternating with the segments of the calyx ; these teeth may perhaps be considered coadúnate bracteas. At first
sight they may readily be mistaken for the calyx, and the real calyx for a corolla, and it is no doubt the presence
of these which gave rise to the remark iu De Candolle’s Prodromus, quoted from Fl. Mexic. ms. ;
“ Fructus junior costatus.” On laying open the proper calyx, five linear-spathulate petals are seen, alternating
with the lobes of the calyx, and shorter than those lohes, situated at the mouth of the tube. Stamens 5,
alternating with the petals, and inserted on the same line with them. Filaments as long as the petals, hairy.
Anthers oblong, 2-celled, opening anteriorly by two fissures. Ovary adherent to the base of the calyx, 1*
celled, 1-ovuled. Style filiform, rather longer than the stamens, glabrous : Stigma capitate, small. Fruit a
small indehibcent(?) capsule, crowned by the withered remains of tbe flower, 1-celled, with one pendent seed
occupying the entire cavity of the cell, globose. Albumen none. Embryo globose, of two hemispherical
cotyledons. Radicle superior, tuberculiform.

Hab. Realejo.— T . cuneiformis is described only as an inhabitant of Brazil. Our specimens precisely
accord with an unnamed Brazilian species in our Herbarium, gathered at Bahia by Saltzmann ; and also with
cultivated specimens from the garden of Gottingen under the name of T . cuneiformis.

H a b . fi. Between San Bias and Tepic.— We possess specimens of what we consider the type of this species
from Xalapa (the original station of Schiede) gathered by M. Galeotti. The present has less acuminated
frequently 5-(as well as 3-) nerved leaves, and shorter flowers. In other respects the two plants appear to
lie the same. The same species is in Andrieux PI. Mexic. Exsicc. n. 342, from between Chaleo and
Gonmacatapee.

Benth. PI. Hartweg. n. 106.
H a b . Between San Bias and Tepic.—This is probably a very general plant throughout Mexico, and we
suspect a very sportive one. Kunth remarks that his B. angustifolia and B . hirtella are probably not different
from it ; and wo are almost of opinion that through the medium of B . splendens, Graham in Bot. Mag. t. 3781,
it may be traced even into B . Jacquinii, H.B.K. (the Ixora Americana, Jacq., Houstonia coccinea, Andr.)

H a b . Between San Bias and Tepic.—This is the same plant with n. 99. of Mr Hartweg’s Mexican
collections, and has been considered by Mr Bentham to be the B . obovata of H.B.K.—but that plant is
described as having a glabrous, 4-sided, square stem, and “ folia quaterna obovato-oblonga, acuminato-mucro-
nata, basi angustata, reticulato-venosa, utrinque glabriuscula ;” characters which do not tally with our plant. Our
B . scabra, is remarkable for the harsh rigid pubescence which more or less abundantly clothes every part of tbe
plant, and which is particularly copious on the young branches and foliage and on the calyces. Leaves 2-3
inches long. The stipules are formed by a broad membrane, uniting the bases of the petioles and bearing a
strong subulate or rather setaceous tooth, and one or two lesser and filamentous ones, which are soon
deciduous. Corymb many-flowered, terminal, trichotomously divided, at the setting on of the branches
-bearing 3 small linear-lanceolate leaves and similar stipules to those of the stem, but having less rigid teeth
or setæ. The calycine teeth are particularly long, subulate and fiexuous ; the corolla an inch and a half long,
scarlet (?), the tube slender, widening upwards, the limb of 4 broadly ovate spreading segments.*
• In Mr Andrieux’s Mexican collections are three plants which seem to be referrible to this genus Bou-
vardia, and which may be thus characterized.
1. Bouvardia Tolucana ; suffruticosa, ramis erectis trichotomis foliisque ternis lineari-lanceolatis sessilibus
pubescenti-scabris, stipulis latis membranaceis snbbisetigeris, corymbis terminalibus trichotomis, dentibus
calycinis brevibus subulatis, corollæ pubescentis limbi laciniis late ovatis brevibus suberectis.
H a b . Toluca. Andrieux, PI. Mexic. exsicc. n. 332. Nom. vernac. Trompeiillo.—The lower part of the
stem is shrubby, the rest herbaceous. The leaves arc scarcely an inch long, quite sessile. Flowers an inch
in length. Corolla clothed with a rather harsh white down, the limb very short.
