508 Porter : A New Variety of Azalea nudiflora. 



petiole, glabrous at the time of flowering or nearly so, entire or some 

 of the larger with few teeth : flowers yellow, the ligules little ex- 

 ceeding the bracts, the fruiting heads about 3 cm. high ; involucral 

 bracts woolly-pubescent, especially so on the edges, in three series, 

 the outermost ones lanceolate-acuminate, the second series ovate, 

 acuminate, exceeding the outermost, and equaling the narrow in- 

 most series : achenes 10-striate, a little less than 1 cm. long, taper- 

 ing into a slender filiform beak of the same length, which is crowned 

 by the bright white pappus of about the same length. 



A species somewhat related to Agoseris grandiflora and its 



allies of the Pacific Slope. Collected on the western slope of the 



mountains west of North Park, Colorado, at an altitude of about 



3000 m., September 2, 1899 (2009). 



New Windsor, Colorado. 



A new Variety of Azalea nudiflora L. 



By Thos. C. Porter 



Azalea nudiflora glandifera var. nov. 



In studying the Azaleas of eastern Pennsylvania, this plant has 

 been under my observation for a number of years and I am now 

 convinced that it deserves varietal distinction. 



Instead of having its peduncles and corolla-tubes clothed with 

 a dense coat of long-acuminate glandless hairs of unequal length, 

 they are sparsely supplied with a single set of gland-tipped hairs 

 of nearly equal length. Both frequently grow together, but no 

 case has been found of the intermixture of the two kinds of hairs 

 on the the same shrub. They are exactly alike in their habit of 

 growth and their foliage, although the corollas of the variety are 

 often larger and sometimes of a deep rose-color. 



Specimens have been collected at Pocono Summit and Mount 

 Pocono in Monroe County ; at three stations near Easton ; at two 

 in Lancaster County, and at two in Delaware County, Pa.
