336 XLIII. LEGUMINOS-dL [ Oxylobium . 
Series I. Callistachys. — Leaves mostly irregularly verticillate. Inflorescence terminal, 
very dense. Ovules about 8. Strophiole none or minute. 
Eacemes short, corymbose. Pod opening to the base. Stipules incon- 
spicuous. Pod smooth inside 1.0. ellipticum. 
Series II. Xiaxiflorae. — Shrubs or procumbent or trailing undershrubs. Leaves mostly 
opposite. Flowers in loose racemes, or few, axillary. Calyx glabrous or slightly pubescent. Ovules 
usually 8. Strophiole none. 
Stems diffuse, procumbent or trailing Leaves obovate, oval, oblong or 
lanceolate, obtuse or mucronulate 2. 0. scandens. 
Series III. Podolobiese. — Leaves mostly opposite. Flowers in loose or slender, axillary 
or terminal racemes. Calyx nearly glabrous. Ovules 4 or very rarely 6. Seeds (where known) not 
strophiolate. 
Leaves pungent-pointed, entire or lobed. Eacemes mostly axillary. 
Leaves lanceolate, entire, rounded or truncate at the base 3. 0. aciculiferum. 
Leaves cuneate at the base, usually toothed or with divaricate, pungent 
lobes. 
Leaves ovate or lanceolate, toothed or shortly lobed 4. O. trilobatum. 
Leaves deeply 3-lobed, the lateral lobes lanceolate and divaricate . . . 5. O. staurophyllum. 
Callistachys linaricefolia, G. Don, Gen. Syst. ii. 117, is not recognisable from the very short 
diagnosis given, but is most probably the narrow-leaved variety of 0. ellipticum. 
1. O. ellipticum (leaves elliptic), R. Br. in Ait. Hurt. Kew ed. 2, iii. 10; 
Bentli. FI. Austr. ii. 16. An erect shrub, low and compact in mountain situa- 
tions ; tall, often straggling, sometimes above 10ft. high when luxuriant, the 
branches silky-pubescent or tomentose. Leaves mostly in irregular whorls of 3, from 
oval-oblong or elliptical, and under lin. long, to oblong-linear, or lanceolate, and 2 or 
3in. long, mucronate, the margins recurved or revolute, coriaceous, glabrous and 
reticulate above, silky-pubescent or villous underneath. Stipules quite incon- 
spicuous. Racemes densely corymbose, terminal or in the upper axils. Pedicels 
1 to 4 lines long. Bracteoles linear, deciduous. Calyx softly villous, 3 lines 
long or rather more ; lobes as long as the tube, acuminate, the upper ones united 
much higher up. Standard much longer than the calyx ; wings and keel shorter. 
Ovary nearly sessile, with 8 to 10 ovules. Pod 4 to 6 lines long, acuminate, very 
villous, opening to the base, glabrous inside. Seeds without any strophiole. —

Var . angustifolium. Leaves long and narrow. I find no other character; the distance of the 
bracteoles from the calyx is very variable. — O. arborescens, E. Br. in Ait. Hort. Kew ed. 2, iii.

2. O. scandens (climbing), Benth. in Ann. Wien. Mus. ii. 70; and FI. Austr. 
ii. 20. A shrub or undershrub with weak procumbent or half climbing branches, 
pubescent when young. Leaves mostly opposite, from obovate or ovate-elliptical 
to ovate- lanceolate or narrow-oblong, obtuse or mucronulate, i\ to 2in. long or 
rarely more, the margins flat, narrowed at the base, reticulate, glabrous when full 
grown. Racemes terminal or in the upper axils, loose, with few yellow flowers. 
Pedicels sometimes as long as the calyx, with two small lanceolate-subulate 
bracteoles at a distance from the calyx. Calyx under 3 lines long, slightly 
pubescent with appressed hairs, the lobes broad, acute, about as long as the tube, 
and nearly equal. Standard about 5 lines diameter ; wings shorter, obovate- 
oblong ; keel rather smaller, the petals scarcely cohering. Ovary stipitate, with 
about 8 ovules. Pod very shortly stipitate, about Jin. long, somewhat curved,
