COLOMHIAX KIPATOKILMS. 329 



canipanulate throat; achenes (iniiiiatuir) l.ii iiiin. loni,'; tlic riijs beset 

 toward the suniniit with a few sessile ghinds. — Nov, Gen. et Spec. iv. 

 110 (1820); DC. Prod. v. 142 (1S36). Osmia sericm (HBK.) Sch. 

 Bip. PoUichia, xxii.-xxiv. 252 (1866). 



Without locality: Hmulwhlt i^- Bonphind (Pur., phot. Gr.); Trlana, no. 

 I'lTS (K.). 



A striking species (with somewhat the habit of a Mikania) errone- 

 ously placed by DeCandolle in his § Cylindroccphala, and by Schultz, 

 who perhaps knew tiie i)lant only from description, similarly referred 

 to Osmia, from which of course it is clearly distinguishable both by 

 its campanulate more loosely imbricated involucre and its hairy 

 receptacle. It is unfortunate that the data of collection appear to 

 have been lost on both occasions on which the plant has been secured.
