 to the tube of the corolla, at the base, inclosed ; filaments chan- 

 nelled inside ; anthers linear, incumbent. Ovarium fusiform, 

 2-celled, 2-valved, 2 inches long. Stigma 2-lobed, sessile ; lobes 

 12 



dilated, roundish, revolute. Ovula disposed in one series in each

 opposite, ovate-lanceolate, acuminated, many-nerved ; flowers 

 numerous, disposed in thyrsoid, oblong panicles. %. F. Native 

 of Peru. Very nearly allied to the preceding, but differing in 

 the leaves and calycine segments being broader, long-acumi- 

 nated, and many-nerved, and in the stamens and peduncles being 

 terete. Corolla violaceous, barely longer than the calyx. Stem 

 purplish, thickness of a writing quil. 



Pendulous-fiovtered Eudoxia. PI. erect. 



Cult. Should either of the species of Eudoxia ever be intro- 

 duced to our gardens, we would recommend their being grown 

 in pots, in a mixture of peat and sand, with the addition of a 

 little loam ; and in winter to be placed on a shelf in a green- 

 house or frame until their hardiness be ascertained.
