involucral bracts of the female plant obtuse, fewer than in the pie- 

 ceding species. Male plants unknown, 



Ti/j>e loeal/ty. — " Vicinity of Flagstaff, northern Arizona. "" Collected 

 by MacDougal; tj^pe in the United States National Herbarium. 



Apparently a good species, but little known, and founded on very 

 innnature pistillate plants, in which the stems are only an inch high. 



29. Antennaria marginata Greene, Pittonia 3 : 290. 1898. 



Like ^1. (ij)i'ic(i^ but leaves glabrous above, or nearly so, and prom- 

 inently nuicronate; staminatc invohicral bracts with rhomboid-ovate 

 and ol)tuse- or acute tips. 



Type in the United States National Herbarium, collected in New 

 Mexico by Fendler; nos. 523 (male), 521a (female). 



New Mexico and southern Colorado. 



A New Mexican ally of ^1. (ipr'ica^ which it appears to replace ahnost 

 entirely in that territory. It is often somewhat sutt'rutescent. and the 

 old leaves are occasionally conduplicate and recurved, us in the pre- 

 ceding species. It is more or less glandular ;ibove, with minute gland- 

 tipped hairs on the pedicels, foliar jjracts, and outer involucral bracts. 

 The typical specimens are from 3-8 cm. high, ])ut the species is often 

 15 cm. high, or more. The involucral l)racts of the male plant are 

 subcoriaceous up to the ovate or lanceolate acutish petaloid portion. 

 It has been collected by G. C. Neallev, no. 1(5, Finos Altos, New Mex- 

 ico, and l>y Rydberg and Vreeland, in southern Colorado. Less typical 

 specimens have been secured by Mr. Heller, no. 3612, near Santa Fe. 



80. Antennaria insularis Greene, Pittonia 3:276. 1898. 



Five to 10 cm. h igh ; leaves 1 )roadly spatulate or obovate, only a) )ruptly 

 acute, glabrous or glabrate above; pistillate involucres 7-8 nun. high. 



Type locality. — "'Islands off' the Alaskan coast." Collected by Baker 

 (Kiska Island) and by Townsend (Adakh Island); type sheets in the 

 United States National Herbarium. 



Alaska (L. M. Turner, 1880) and adjacent islands. 



This bears a superficial resemljlance to the southern xi. marg'tnata^ 

 but is a broader-leaved species, with heads more like those of A. apnea. 



31. Antennaria oxyphylla Greene, Pittonia 4: 281. 190l. 



Fifteen to 25 cm. high; leaves spatulate-obovate. permanently 

 tomentose on both surfaces, 2 cm. long or less; heads 6-15; involucres 

 7-8 mm. high; bracts in about 1 series, imbricated, "all acute and 

 of a rather dull white." rarely pinkish. Male plant unknown. 



Type locality. — "" Spanish Basin, Gallatin Co., Montana." Collected 

 by Rydberg and Bessey. no. 5118; type in the herbarium of E. L. 

 Greene. 



Southern Wyoming to the Black Hills of South Dakota. Montana, 

 and southeastern British Columbia. 



This is a dry ground species, in general appearance resembling ^1. 

 roHca and A. jxirclfolla. but its comparatively large heads, with numer- 

 ous involucral l)racts, show it to b(^ an ally of A. ohovata and ^1. ap)i'!ca. 

 The involuci-al bracts are not as narnnv as those of the former and 

 more acute than those of the latter. Dr. Greene founded the species
