A species said to resemble Zehites montana of Kunth, with pubescent branches; leaves 
obovate, cordate, acuminate, coriaceous, densely pubescent above, woolly beneath, sessile ; 
racemes axillary, longer than the leaves, bearing several lax pedicellate flowers, rather 
less than 1 inch long; sepals obtusely ovate, glabrous ; corolla hypocrateriform ; stamens 
included.

A plant known only to Velloz. It isa stoutish climber, with slender flexuose branch- 
lets, having axils 2—4 in. apart; leaves oblong-elliptic, acute at the base, acuminate, 
4-43 in. long, 13-22 in. broad, on stoutish reflexed spreading petioles 3—1 in. long; 
raceme terminal, simple, spicately flowered, 4 in. long, on a peduncle bare at the base for 
13 in., bearing upwards about 15 simple, alternate, rather small flowers on pedicels 2 lines 
long, supported by 2 opposite, small, acute bracts; sepals acute, 1 line long; corolla 
(apparently in bud) 5 lines long, yellow; tube very short; segments linear-subulate, 
erect, 3 lines long; stamens partly exserted; disk of 5 free lobes surrounding the 2 
oblong ovaries; style short; clavuncle incrassate. 
Müller, who did not see this plant, refers it doubtfully to Forsteronia; but it differs 
from that genus in its simple, spicate inflorescence with alternate larger flowers. For 
the same reasons it cannot belong to Thyrsamthus nor to Exothostemon. From Lchites 
proper it differs in its undeveloped flowers, by its very short tube and subexserted 
stamens ; but it accords in its spicate inflorescence. Till more is known of it, the species 
will remain in Zchites, with an exceptional development in the shape of its corolla. 
The opposite bracteoles at the base of the pedicels are omitted by the Paris draughtsman ; 
but they are shown in the analytical figure. 
'TEMNADENIA. 
A group of species, uniform in their characters, mostly climbing plants with opposite 
elliptie leaves generally cordate at the base and pubescent ; inflorescence more frequently 
lateral, on a deflexed peduncle supporting 2 floriferous branches bearing several pretty 
flowers; fruit of 2 terete very woolly follicles, conjoined at the apex. 
TEMNADENIA *, nob. Sepala 5, lanceolata, tenuiter acuminata, margine membranacea, quincuncialiter 
imbricata, intus squamula sublaciniata singulatim munita. Corolla subhypocrateriformis 5 tubus 
cylindricus, parallele striatus, sepe sub medium subito constrictus, superne infundibuliformis, 
fauce nudus aut in gula carnosula crebre costulatus, vel raro in lineola transversa contractus. 
Segmenta 5, oblonga, oblique et rotundate dolabriformia, horizontaliter expansa. et dextrorsum 
convoluta. Stamina 5, inclusa, ad constrictionem tubi inserta; filamenta brevia, pilosa, ex eeng 
piloso orta; anthere lineares, acuminate, in conum subcoh:rentes, imo acute bifurcate. Discus 
cylindricus, fere ad basin quinquefissus, lobis oblongis obtusis emarginatis ; ovaria 2, subzequilonga 
aut paullo longiora. Stylus tenuis; clavuncula incrassata, cylindrica, imo membranula peltata 
* From réurw (scindo), Aäis (glanda), from its disk cleft into 5 segments nearly to the base.
