 Eysenhardtia, Jmorpha, Paryella, Apoplanesia, and Asagrcea. 



IV. LOTUS SERIES. 



Lotus' (Fr., Lotier) has irregular resupinate hermaphrodite flowers. 

 On the edges of the concave receptacle, lined with glandular tissue,

androceum. The live equal or 

 unequal lobes of the gamo- 

 petalous calyx are approxi- 

 mated into two lips. 2 The 

 corolla is papilionaceous. Its 

 standard, obovate ovate acu- 

 minate, or suborbicular, ta- 

 pers slightly at the base to 

 form a short claw. The wings 

 are obovate, very unsymme- 

 trical towards the base of the 

 shortly unguiculate limb. 

 The incurved or inflexed 

 beaked keel is gibbous on both 

 sides. There are ten diadelphous stamens, the nine inferior being 

 united into a tube cleft above, while the tenth or vexillary 

 stamen is free. The five alternipetalous stamens are longer than 

 the rest, and their filaments are more dilated above, below the 

 introrse or subbasiflxed two-celled anthers, which dehisce longi- 

 tudinally. The gyna?ceum, inserted in the bottom of the receptacle, 

 consists of a sessile multiovulate ovary, surmounted by a glabrous 

 style, naked or bearing an appendage of variable form, and with a
