 RocHELiA PATENS, Nutt. in Jour. Acad. Philad. vii. 44, founded on a specimen collected by

12. AMSfNCKIA, Lehm. (In memory of Wm. Amstnck, a burgomaster 

 of Hamburg aud benefactor of the botanic garden.) — Rough-hispid annuals (W.

 flowers, sometimes the lowest and rarely (in the last species) all leafy-bracteate ; 

 the corolla yellow, slender, with open throat, either wholly naked or with minute 

 bearded crests. Stout bristles of the herbage commonly with pustulate-dilated 

 base. Calyx-lobes in several species disposed to be occasionally united '2 or 3 

 together almost to the top. Flowers in most species all heterogone-dimorphous, at 

 least in the insertion of the stamens ; when these are high the throat of the corolla 

 is quite naked. — Lehm. Del. Sem. Ilamb. 1831, 7; Fisch. & Meyer, Ind. Sem.
