Rivea, recognized by its four-celled capsule, stigmas two, linear, 
cylindrical or lamellate; 4rgyreia, ovary four-celled, stigmas 
capitately two-lobed; Leftsomia, ovary two-celled, cells two- 
seeded, stigmas capitately two-lobed. With this view of the 
genera the plant under consideration will revert to Argyreia. 
Descr. A climbing plant of very great extent, the herbaceous 
portion of the stem and branches, the petioles, peduncles, bracts, 
calyx, and tube of the corolla excessively «villous, with long, 
spreading hairs ; dranches terete. Leaves large, exactly cordate, 
tipped with a soft mucro, bright green above and scarcely hairy, 
the margin and whole surface beneath clothed with pale down 
intermixed with appressed hairs, abundant on the numerous reti- 
culated, prominent nerves. Peduncle long and twisted, generally 
longer than the petiole, bearing, according to the strength and 
vigour of the plant, one or more flowers ; in the latter case sub- 
cymose, lax (not compact or capitate). Bracts in opposite pairs, 
some distance from the calyx, linear or lanceolate. Sepals ovate, 
somewhat imbricated, erect and appressed. Corolla very large, 
of a beautiful deep lilac colour, subhypocrateriform rather than 
campanulate ; the fuée long, a little contracted below the limb; 
the /imd ample, spreading almost horizontally, indistinctly five- 
lobed, the broad lobes emarginate in the centre, the edge a 
little undulated. Stamens quite included within the tube. Ovary 
sunk into a large, fleshy, hypogynous disc. Sfy/e filiform. Stagma 
capitate, bilobed, /odes granulated.

We take the opportunity of remarking here that Mr. Moore has obligingly 
assured us that seeds of Salvia porphyrata (Tab. 4939) were undoubtedly received 
from Texas along with those of other Texian plants, such as Gaura Lindhei- 
meriana, Ungnadia speciosa, etc. .
