WOOTOlSr AND STANDLEY FLOEA OF NEW MEXICO. 483 



This form seems to us distiuct enough to rank as a species. It certainly is much 

 more easily recognized than most of the species of the family. We have never seen 

 it occurring with the other species nor have we ever seen intergradient forms. 



2. Pseudocymopterus montanus (A. Gray) Coult. & Rose, Rev. Umbell. 74. 1888. 

 Thaspiurnf montanum A. Gray, Mem. Amer. Acad. n. ser. 4: 57. 1849. 



Type locality: Sunny declivities at the foot of mountains, along Santa Fe Creek, 

 Nev.^ Mexico. Type collected by Fendler (no. 276). 



Range: Wyoming to Arizona and New Mexico. 



New Mexico: Mountains west of Grants Station; Santa Fe and Las Vegas moun- 

 tains; Black Range; WTiite Mountains. Meadows and damp woods, chiefly in the 

 Transition Zone. 



3. Pseudocymopterus tenuifoHus (A. Gray) Rydb. Bull. Torrey Club 33: 147.

Thaspium f montanum tenuifolium A. Gray, PL Wright. 2: 65. 1853. 



Pseudocymopterus montanus tenuifoHus Coult. & Rose, R,eA'. Umbell. 75. 1888. 



Type locality: "Hillsides of Coppermine Creek, New Mexico." Type collected 

 by Wright (no. 1107). 



R.'Vnge: New Mexico and Arizona. 



New Mexico: Mogollon Mountains and Black Range to the Organ Mountains and 

 southward. Canyons and faces of cliffs, in the Transition Zone. 



Apparently this is a very good species, distinguished from P. montanus by ita 

 tufted habit, much elongated, very narrow leaf segments, and pale flowers. It is 

 found in different situations, too, preferring crevices of cliffs in the deep canyons, 

 always growing in shade. 



4. Pseudocymopterus filicinus Woot. & Standi. Contr. U. S. Nat. Herb. 16: 158. 



1913. 



Type locality: Bear Mountain near Silver City, Grant County, New Mexico. 

 Type collected by Metcalfe (no. 165). 



Range: Mountains of western New Mexico. 



New Mexico: Bear Mountain; Mangas Springs; Holts Ranch; Pinos Altos. 



A very handsome plant, for the family, its leaves strongly suggesting some of the 

 ferns. It is distinguished from our other species by the very numerous leaves of 

 peculiar form and by the small umbels which usually but slightly exceed the leaves. 



5. Pseudocymopterus multifidus Rydb. Colo. Agr. Exp. Sta. Bull. 100: 257. 



1906. 



Pseudocymopterus montanus multifidus Rydb. Bull. Torrey Club 31: 574. 1904.

This becomes much larger than is suggested in the original description or in Coulter 

 & Nelson's flora, being. often 30 or 40 cm. high. 



18. OXYPOLIS Raf. 



Smooth erect herb 30 to 60 cm. high, from fascicled tubers; leaves simply pinnate, 

 with 5 to 9 leaflets; flowers white; involucre and involucels wanting; calyx teeth
