284 NATURAL HISTORY OF PLANTS. 



tube furnished outside with elliptical rather prominent coloured glands 

 (usually cc) ; lobes nearly equal, obtuse imbricated. Corolla perigy- 

 nously inserted at top of receptacle; standard broadly cordate, 

 shorter than keel, emarginate or cut at apex, callous within at base 

 above short claw ; wings with longer claws ; limb unevenly ovate ; 

 keel-petals resembling and longer than wings. Stamens 10, in- 

 serted with corolla, 1-adelphous; filaments connate into a sheath 

 cleft above ; anthers ovate-elliptical, furnished with an oblong gland 

 at back below apex. Germen shortly stipitate ; stalk slender excen- 

 tric; unevenly ovate, compressed, sparingly glandular at base; 

 ovules 6, 2-seriate, obliquely descending; style slender, curved at 

 apex, tubular ; summit truncate stigmatiferous. Legume exserted, 

 unevenly ovate, apiculate turgid 1 -seeded (?). — A rigid branched 

 hoary shrub ; twigs ending in sharp spines ; leaves simple scattered 

 sessile, rather thick ; stipules minute narrow ; flowers 1 subspicate 

 along ends of spinescent twigs ; pedicels very short ; bracts flowered 

 caducous ; bractlets 2, inserted at middle of pedicel {California 2 ). 



IV. LOTEiE. 



106. Lotus L. — Flowers irregular resupinate ; receptacle scarcely 

 concave. Calyx gamosepalous ; teeth or lobes 5, nearly equal 

 {Krokeria, Microloim), or dissimilar and connate into two lips ; lowest 

 tooth or lobe sometimes longer than others. Corolla papilionaceous ; 

 standard suborbicular, obovate or ovate-acuminate, contracted at 

 base into an often short claw ; wings unevenly obovate ; keel curved 

 or inflexed, often 2-gibbous, beaked. Stamens 10, 2-adelphous (9-1) ; 

 alternate filaments dilated at apex ; anthers uniform. Germen sub- 

 sessile ; ovules oc ; style soon inflexed, glabrous, either continuous 

 or furnished on inner side with a tooth or twig (Uulotus) or a mem- 

 brane {Tetragonolobus) ; stigma terminal or lateral. Legume oblong 

 or linear, subterete, straight curved or arched {Krokeria, Micro/otus), 

 rarely turgid {Krokeria), bare or longitudinally 4 -winged {Tetragono- 

 lobus) outside, bare or slightly stuffed or more rarely septate within 

 between seeds. Seeds globose, suborbicular, or lenticular, exarillate. 

 — Herbs or undershrubs, glabrous silky or hirsute ; leaves 3-5- 

 foliolate ; 3 leaflets close together at apex of petiole ; 1, 2 near base
