NATURAL HISTORY OF PLAXTS. 



Beside Eiciuus is fouud Homonoija, coiisistiug of slu'ubs from 

 tropical Asia, whose flowers are coustructed iu the same way, the 

 male calj'x being geuerally triiiierous, the cells of the anthers con- 

 fluent, and the gynieceum being reduced to two carpels. The 

 flowers of both sexes are in distinct spikes or racemes, and the leaves 

 are penuinerved. Cloelodiseus, consisting of Indian plants, has also 

 polyadelphous stamens, but the staminal bundles, instead of being 

 inserted towards the centre of the flower, are thrown out toward the 

 periphery of the receptacle, whose centre is occupied by a sort of 

 circular concave disk.
