Peru: similar habitat, between Pampano and Huaytara, west slopes 

 of the Andes between 13*^ and 14^ S. Lai, above Pisca, alt. 1800 m 

 (Weberbauer n. 5404) (type in Berlin Herbarium; photograph and frag- 

 ments in Gray Herbarium). 



This new genus of the Helianthoideae-Verbestneae^ whose position in the system 

 may well be between Oyedaea and Verbesijia, presents a remarkable combination of 

 characters. In habit and involucre it is very similar to Simsia, while the pales recall 

 Enceliopsts; but its chief diagnostic characters are found in the achene, which with 

 its silky-villous black body and crustaceous-corky base and margin is again strikingly 

 suggestive of EnccHopsis, although in habit and pappus the two genera are widely 

 different. The pappus of Syncretocarptis, of two flattened and fimbriate awns separa- 

 ted by two pairs of stiff basally thickened and united squamcllae, approaches most 

 nearly that of Viguiera, but the genus, although not unlike various Vtguierae in 

 habit and most other features, is at once distinguished by its corky-margined fruit, a 

 character of the Verbesina group, and not observable in young achenes. In not all 

 the achenes, even those seemingly mature, is the wing developed, but there is always 

 a- crustaceous subpcdiform base (also found in various related genera), and a winglike 

 laterally glabrous dorsally silky-ciliate margin to the achene which probably ultimately 

 suberizes in all perfect fruits. In the related genus AcHnomeris, also, both winged 

 and unwinged achenes are said to occur in the same head. 



I wish to express my thanks to Dr. Engler and Dr. Diels of the Berlin Herbarium 

 'or the privilege of describing this interesting new genus.
