oppositis 3-5-partitis, segmentis linearibus plerumque integerrimis ; 

 capitulis laxe corymboso-cymosis breviuscule peduuculatis ; iuvolucro 

 extenio indistincto e bracteis 1-3 parvis, iuteruo seu proprio e bracteis 

 G-8 ovatis biseriatis ; anuulo corolla; tubi barbato ; ramis styli fl. 

 herm. appendice subulato sui)eratis ; acheiiiis obloiigis margiiiibus serie 

 tuberculoium quasi alatis aut calvis aut aristis 1-2 teiiuibus instructis 

 (faciebus aut laivibus aut birtello-muriculutis), iutimis minus perfectis 

 angustioribus imniargiiiatis. — Near Fort Lowell, Arizona, along 

 streams, Leinmon, 1880. Santa Cataliua Mountains, Priiirjle 1881. — 

 Tlie delicate short awns of the akenes are either naked or S2)aring]y 

 denticulate, the denticulations spreading or some of them recurved. 

 The minute cupule at the summit of the ovary and akene is within 

 the base of the corolla, therefore an epigynous disk. — It is becoming 

 evident that Leptosyne^ DC, Piigiopappus, Gray {Agarista, DC), 

 and Coreocarpns with Acoma, Benth., must be combined into one 

 genus, which is the counterpart ou the western side of North 

 America of Coreopsis on the eastern, and from which it is distin- 

 guished by its fertile ray-flowers and by the annulus of the disk-corolla. 

 The latter is a peculiarity of the genus. Leptosyne maritima^ as we 

 have it in cultivation, occasionally develops a short paleaceous awn 

 to each margin of the summit of the akene. Pugiopappus (of three 

 described species) and Coreocarpns form good sections, and the latter 

 approaches Bidens.
