digitate, the veinlets extending to the edge and often produced into minute teeth. Peduncles, 
racemes, or flower-heads axillary (or apparently terminal by the reduction of the upper floral 
leaves ), never leaf-opposed. Upper stamen free, the others united in a slieatli. Ovules 2 or more.

of the staminal tube. Pod usually included in the calyx 27. *Trifolium. 
Tribe IV. Euloteae. — Herbs, rarely shrubs. Leaves pinnate, or sometimes apparently 
digitately 3-foliolate, the ■ lowest pair of leaflets taking the place of stipules ; leaflets entire.

Tribe V. Craleg'ese. — Herbs not twining, shrubs, or rarely trees or tall ivoody climbers. 
Leaves pinnate, rarely reduced to 3 or 1 leaflets. Stipellce none, or setaceous in a few pinnate 
genera. Upper stamen usually free, at least at the base, the others united in a sheath, very rarely 
all united ; filaments filiform. Ovules 2 or more ( except in Indigofera linifolia and in Psoralea). 
Pod not articulate, 2 -valued ( except Psoralea). 
Ovule 1. Fruit small, the pericarp adhering to the seed. Herbs or shrubs 
with black glandular dots. Leaflets (in Australia) 1 or 3, sometimes 
toothed 29. Psoralea. 
Ovules 2 or more (1 in I. linifolia). Anthers tipped with a small gland. 
Pod 2-valved. Herbs or shrubs, sometimes glandular. Leaflets entire. 
Hairs often appressed and attached by the centre 30. Indigofera. 
Ovules 2 or more. Anthers without glands. 
Racemes or flowers terminal or leaf-opposed. Herbs or shrubs. 
Stamens all united in a sheath, open on the upper side. 
Leaflets 3. Flowers in racemes. Seeds strophiolate 21. Goodia. 
Leaflets few. Petals not exceeding the deeply lobed calyx. Seeds 
strophiolate, with a straight radicle 31. Laaiprolobum. 
Leaves imparipinnate ; stipules semi-sagittate. Stamens mona- 
delphous. Pod terete 32. *Galega. 
Upper stamens usually free, or all united in a closed tube .... 33. Tephrosia. 
Kacemes in a terminal panicle. Tall woody climbers. Pod hard . . 34. Millettia. 
Kacemes or flowers axillary. Herbs or shrubs. 
Style not bearded (rarely a small tuft of hairs on the stigma in 
Tephrosia). 
Pod linear, rarely short and oblong ; valves thin or coriaceous, flat 
or convex when ripe 33. Tephrosia. 
Pod long, narrow and thick, the endocarp continuous with the 
transverse partitions between the seeds 35. Sesbania. 
Pod 1-seeded (ovules 2), muricate. Plant glandular. Anthers with 
confluent cells opening in unequal valves 38. Glycyrrhiza. 
Style bearded under the stigma. Pod turgid, membranous or 
coriaceous. 
Petals acuminate 36. Clianthus. 
Petals obtuse 37. Swainsona. 
( Abrus , and a very few pinnate-leaved Phaseolea;, may have the technical characters of 
Galege ce, but are distinguished by their herbaceous more or less twining stems.) 
Tribe VI. Hedysareae. — Pod separating into 1 -seeded articles, or the whole pod 1-seeded 
and indehiscent (except Pycnospora), and rarely Desmodium). foliage and inflorescence, in the 
Australian genera, either of Galegess or of Phaseoleee. 
Leaves pinnate with several leaflets, as in Galegece. Stamens united in a 
sheath, or in 2 bundles of 5 each. 
Tall shrubs. Articles of the pod oblong, striate 39. Ormocarpum. 
Herbs. Articles of the pod square or semiorbicular, flat 40. jGschynomene. 
Herbs. Articles of the pod folded over each other within the calyx . . 41. Smithia. 
Pod ripening beneath the soil, oblong, reticulate, indehiscent, subtoru- 
lose, continuous within. Seeds 1 to 3 42. * Arachis. 
Leaves with 2 leaflets. Bracteoles large, enclosing the flowers. Stamens 
all united. Anthers alternately long and short 43. Zoknia.
