Umb. 182 1900). C. Fenclleri and its variety Xewberryi, and C. 

 nieg-acephakis. This has the same character as Rhysopterus, 

 except that the leaf sheaths are inclined to be a little fibrous, 

 noticeably so in C. meg-acephalus (rays also absent in this 

 species), leaves more divided and less glaucous as rule, pedi- 

 cels almost none, flowers mostly white, fruit oval to obovate, 

 J)-4 lines long, with lateral wings always developed and usually 

 at least one dorsal and as wide or wider than the body, the 

 v/ing consisting of a thickened area at or near the middle of 

 its cross-section, which is connected with the body of the seed 

 by a very thin section, the outer end of the cross section taper- 

 ing abruptly or gradually to a thin edge ; this gives the seed 

 an appearance of being surrounded by a thickened ring, in C. 

 glomeratus the wings are often corrugated almost as much as 

 in C. corrugatus. 



The above three groups form a natural division of the 



leaves which are leathery but not rigid nor aculeate tipped, 

 acaulescent, and growing on low lands or mesas, not among 

 solid rocks, in the Lower Temperate Life Zone mostly. 



Cymopterus Owenensis n. sp. 



Allied to C. Jonesii. Smooth throughout ; acaulescent and 

 caespitose; leaves coriaceous and rigid, ternate and then pin- 

 nate and with the large ovale leaflets incisely 3-5-lobed and 

 covered with sharp, short and deltoid teeth, petioles short, 

 margined for half their length with the abruptly enlarged hya- 

 line sheaths, purplish as well as the peduncles; peduncles 4-6 

 inches long, ascending, stout ; involucre none ; involucels a 

 hyaline collar very small and a few lanceolate hyaline- 

 margined small bracts ; flowering pedicels about 1 line long, 

 many; rays about equal, 1 inch long and about 10, stout; very 

 immature fruit with conspicuous wiiigs; evidently with large 

 fruit wings when mature ; if it were not for the evident wings 

 this would be taken for a Peucedanum of the Euryptera sec-

The following groups embrace the rest of the genus 

 which division is characterized by dense clusters of fibrous 

 nostlv short lenf sheaths mostly with old and woody petioles, 

 caespitose stems (less so in Rosei and basalticus). from deep 

 and long rarely fleshy roots, much branched crowns with short
