Author(s):
(Radlk.) Niedenzu
Concept:
E. Launert FTEA 1968
Description:
Climber up to 5 m. in length; younger stems densely covered with short soft white sericeous hairs, older stems very finely pubescent or glabrescent. Leaf-lamina ovate-cordate, 6-12 x 4-9.5 cm., acute to shortly acuminate, membranous, pubescent or glabrescent above, grey-tomentose beneath and with 2 large glands near base (usually concealed by the indumentum); petiole 1-3 cm. long, densely sericeous with usually 2 small glands above the middle. Flowers in dense axillary and terminal corymbs, +/-1.5 cm. in diameter, evil-smelling; peduncles and rhachis sericeous; pedicels 1-1.5 cm. long, sericeous; bracts ovate; bracteoles lanceolate or linear-subulate. Sepals broadly ovate from a narrowed base, 2-2.5 mm. long, sericeous outside. Petals pale yellow, ovate, 6-7 mm. long, shortly clawed, carinate, subhastate at the base, usually reflexed. Stamens with sub versatile oblong anthers 2.3-2.5 mm. long; filaments somewhat fleshy. Ovary densely sericeous; styles 2.5-3 mm. long, fairly stout, sericeous. Lateral wing of samara oblong-elliptic or oblong-obovate, 1-2 cm. in diameter, with entire margins; dorsal wing absent. Fig. 8.

Author(s):
S. Moore
Concept:
E. Launert FTEA 1968
Description:
Woody climber up to 5 m. or more in length; younger stems usually greyish-pubescent, older ones glabrous, densely lenticellate. Leaf-lamina ovate or broadly elliptic, 4.5-9.5 x 3.5-5 cm., acute or obtuse, rounded or cordate at the base, coriaceous to chartaceous, glabrous (younger ones sometimes +/- sericeous); petiole 1.5-3 cm. long, with a pair of glands near apex. Inflorescence 5-12 cm. long, many-flowered; pedicels 5-18 mm. long, decussate, distinctly articulate; bracts linear-lanceolate, 2-3 mm. long; bracteoles very short, subulate. Flowers 2.3-2.5 cm. in diameter. Sepals oblong, 4-5 mm. long, sericeous outside. Petals bright yellow, oblanceolate to oblong, 10-12 mm. long, rounded at apex, cordate or subsagittate at base, shortly clawed. Anthers linear, 3-4 mm. long, orange; filaments glabrous, somewhat incurved. Samara 1.5-2 cm. in diameter; lateral wing divided into 6 oblanceolate-linear usually denticulate lobes; dorsal crest with a spine 8-10 mm. long. Fig. 3.

Acridocarpus alopecurus Sprague

Author(s):
Sprague
Concept:
E. Launert FTEA 1968
Description:
Spreading shrub or woody climber. Young shoots ferrugineously sericeous, older ones somewhat pubescent but usually glabrescent, lenticellate. Leaf-lamina obovate, obovate-oblong, elliptic or oblanceolate, 11-18(-20) x 2.8-6.5(-8.5) cm., shortly acuminate, rounded or cuneate at base, chartaceous or chartaceous-membranous, usually glabrous but sometimes finely pubescent, with 7-11 lateral nerves, mostly with 1 or 2 glands beneath near insertion of petiole, and often with a pair of smaller ones near the apex at base of apiculum; petiole 4-8 mm. long, robust, canaliculate, finely pubescent or glabrous. Inflorescences mostly axillary (rarely terminal) racemes, many-flowered; axis very stout, often thickened (sausage-like), very short and very shortly peduncled or often elongate and then with a longer peduncle (up to 2 cm.), +/- densely ferrugineous- or rubiginose-sericeous; bracts broadly ovate-triangular or lanceolate-triangular, usually acute, persistent, inserted at base of or some way below pedicel, with a pair of glands above or at the very base; bracteoles very small, sometimes with a single gland at base. Flowers +/- 2.5 cm. in diameter. Calyx with usually 3 (rarely 5) circular glands; lobes subcircular or ovate to ovate-oblong, 3-3.5 mm. long, glabrous. Petals golden yellow, subcircular to broadly obovate, 10-12 x 7-9 mm., shortly clawed, deeply lacerate on the margin. Stamens with oblong anthers 3.5-5 mm. long; filaments cylindrical, 1-2 mm. long, glabrous. Ovary +/- densely sericeous; styles 2, 0.7-1 cm. long. Wing of samara (see fig. 1/5) obliquely obovate to obovate-oblong, 3.5-4.5(-5.5) x 1.7-2.1 cm., with the upper margin straight or slightly curved towards the apex, very rarely somewhat constricted at the base, distally obliquely truncate, clasping the nut halfway or somewhat nearer to the base.

Oliv.
Concept:
E. Launert FTEA 1968
Description:
A tall woody climber (sometimes creeping) up to 4 m. or more in length; stems densely ferrugineous-pubescent when young, becoming glabrous when older. Leaf-lamina ovate, broadly lanceolate, lanceolate-oblong or oblong, 6-13 x 2-6.5 cm., acute or apiculate, or sometimes subobtuse, cordate, rounded or cuneate at base, densely ferrugineous-pubescent on both surfaces when young, later usually glabrous, dark green above, grey-green beneath, with the secondary and tertiary nerves +/- strongly developed; petiole 0.5-2 cm. long, canaliculate, usually glabrous; stipules broadly lanceolate, obovate or oblong, +/- elliptic, 2-15 x 1-8 mm., deciduous or +/- persistent, usually glabrous. Flowers many in terminal or axillary corymbose panicles, 1.5-2.5 cm. in diameter, zygomorphic; bracts 0.5-2.5 mm. long, deciduous; bracteoles +/- 1 mm. long, +/- persistent. Sepals oblong-elliptic, 2-3 x 1-1.5 mm., sericeous outside, glabrescent. Petals white to cream or yellow-orange (? red), 6-9 x 4-5 mm., distinctly clawed, deeply fimbriate at margins. Stamens with ovate-oblong anthers 1-1.5 mm. long; filaments 4-7 mm. long, minutely pubescent. Ovary densely sericeous; styles 4-8 mm. long, glabrous. Samara with lateral wing circular or broadly ovate, 4-5 cm. in diameter, glabrous, somewhat undulate; dorsal wing crest-like, 1.5-3 x 0.4-0.6 cm.
