This plant is said to yield a claret-coloured gum. 



3. O. cynanchifolius, Mast. A climber, with slender terete branches. 

 Leaf-stalks 1—2 in. long, glanduliferous at the apex • leaves mem- 

 branous, glabrous, 2—4 in. long-, 1-2 in. wide, oblong, cordate, acumi- 

 nate, 1-nerved, sinuate, sometimes 3-lobed, lobes pointed. Tendrils 

 axillary, some sterile, others fertile. Flowers numerous, small, in ter- 

 minal or axillary panicles. Calyx deeply 5-parted, segments narrow, 

 ovate-oblong, linear-spotted, membranous at the edges, valvate in the 

 bud. Petais membranous, oblong, obtuse, jagged at the edges, shorter 

 than the segments of the calyx. Corona of fine hairs, sometimes nearly 

 wanting. Filaments subulate ; anthers linear-oblong, obtuse, much 

 longer than the filaments. Rudiment of the pistil minute. — Modecca

9. ATHERANTHEEA, Mast, in Trans. Linn. Soc. ined. 

 {cum ic. xylog^) 



Flowers dichlamydeous, unisexual. Male fl. : Sepals 5, distinct, 

 originally equal and equidistant, afterwards, owing to the irregularity 

 of two of the petals, two of the sepals are widely separated from 

 each other. Petals 5, quincuncially imbricate, 3 outer ones flat, 2 

 inner ones larger and concave. Corona none. Stamens 10, mona- 

 delphous at the base, 5 fertile opposite to the petals, 5 sterile \ fila- 

 ments flat, twisted ; anthers subglobose, 1 -celled, attached to the fila- 

 ment on the dorsal surface, originally introrse, but from the cur- 

 vature of the filament ultimately extrorse, dehiscing longitudinally by 

 a single chink ; pollen spherical ; connectives of the anthers ? pro- 

 longed into horn-like processes which meet in the centre of the flower. 

 Pistil rudimentary. Style minute. — A climbing herb, with alternate, 

 stalked, angular leaves. Tendrils axillary. Flowers panicled. 



1. A. paniculata, Mast. A climbing* herb with compressed, gla- 

 brous, deeply furrowed stems. Leaves membranous or rather fleshy, 

 green on the upper surface, paler beneath, cordate (basal lobes diver- 

 gent), angular or ovate-rhomboid, acuminate, repand- dentate, 3-5- 

 nerved, arch-veined, 2-4 in. long, 2 in, wide. Petiole shorter than 

 the blade, terete, channelled on the upper surface, eglandulose. Sti- 

 pules ? Tendrils axillary, thickened at the ftxtremity. - Male 



fl. : numerous, greenish, somewhat bell-shaped, arranged in lax 

 branching, leafless, axillary panicles exceeding the leaves in length. 

 Peduncles and pedicels slender, pedicels spreading horizontally, rather 

 longer than the flowers • bractlets minute, awl-shaped. Petals twice
