MANDEVILLA LINEARIS, N. E. Brown, sp. n. Caules volubiles, graciles, puberuli. Folia 
breviter petiolata, linearia, acuta, supra glabra, subtus tomentosa, marginibus fere 
vel usque ad costam revolutis. Racemi breves, pauciflori, minute puberuli. 
Bracteze parvee, acuminatze. Pedicelli brevissimi. Sepala parva, deltoidea, acuminata. 
Corolla infundibularis, 23 poll. longa, recta, extra glabra, intra ad mediam dense 
barbata. Stamina inclusa, filamentis ellipticis glabris, antheris subacutis basi 
breviter cordatis vel emarginatis. 
Stem twining, slender, puberulous. Leaves opposite, 2—21 in. distant, petiolate, 
thinly coriaceous; petiole 1-14 lin. long, rather slender, puberulous; blade 11-21 in. 
long, linear, acute, obtuse at the base, with the margins revolute nearly or quite to the 
midrib, glabrous and shining, with an impressed midrib above, tomentose, with a 
prominent midrib beneath, the tomentum usually hidden by the revolute margins. 
Racemes short, 4—3 in. long, more than half of which is peduncle, 3-4-flowered, very 
minutely puberulous. Bracts about # lin. long, ovate, acuminate.  Pedicels aiternate, 
about 1 lin. long, rather stout. Calyx-lobes about 14 lin. long, deltoid, acuminate, sub- 
glabrous or very minutely puberulous, each with a small ovate scale at the base inside. 
Corolla about 2j in. long, funnel-shaped, straight, 5-lobed, glabrous outside, the middle 
part of the tube inside densely covered with deflexed white hairs; tube cylindric and 
about 1$ lin. diam. for $ of its length, upper part much enlarged, subeampanulate ; 
lobes about 5 lin. long, hatchet-shaped, with an ineurved apiculus, one side being 
dilated into a subrectangular, obtuse, membranous lobe. Stamens 5, included, inserted 
at the top of the narrow part of the tube; filaments about ? lin. long, elliptic, glabrous ; 
anthers 2 lin. long, linear-oblong, subacute, slightly narrowed at the emarginate or 
shortly cordate base. Disk of 5 oblong lobes. Ovary glabrous; style about 1} in. 
long, filiform, glabrous; stigma subquadrate when viewed sideways, obtuse, 5-winged.
