(Naudinia, Rick. Cub. Harrera, Macf. Miconiastrum, Naud. M iconise s«tf. Laceraria, Naud.) 



Calyx campanulate : tube contracted at the top ; limb produced, spreading, with the teeth 

 short, bluntish, or wanting. Anthers 8-10 (-12), beaked-subulate, inflexed above the ovary, 

 opening with a single terminal pore : cells connected. Ovary adherent, crowned by a gla-

 minute. — Low trees or shrubs, not hispid ; leaves petioled, at length glabrous above, often 

 whitish with scaly or tomentose down beneath ; panicle terminal : cymes corymbiform, with 

 the flowers stalked and the bracteoles minute or none ; petals obovate.

 jointed nor bearing bracts at the top. — Branchlets, panicle and under side of leaves whitish 

 with scaly or powdery down.

 {non DC). Harrera gerascanthoides, Macf — A low tree, 20' high, remarkable for the white, 

 powdery down of the branchlets and the inflorescence ; leaves 3"-5" long, variable in breadth, 

 bluntish at the tapering point, entire : petiole 1" long ; panicle oblong : the primary branches

3. argyrophylla. Leaves elliptical-lanceolate, leprous with a scaly epidermis beneath. — 

 Rich. Cub. t. 44 bis : wrong in certain analytical details, as for instance the bristles on 

 the ovary, ascribed by Richard to his genus Naudinia, but which do not in reality exist. — •
