ACCBSSIONS TO ANTENNARIA. 149 



oval, not more obtuse than those of the fertile ; pappus-bristles 

 of the sterile flowers with acutely lanceolate and finely serrated 

 flattened tips. 



Type specimens gathered by the writer in thin woods among 

 rocks near the summit of Maryland Heights, Maryland, over- 

 looking Harper's Ferry, 10 May, 1908, the plant not otherwise 

 known. 



Antbnnaria Onbidica. Slender and delicate for one of 

 the broad-leaved group, the stolons very short, with foliage 

 fully developed at flowering of the plant : leaves 1 to 2 inches 

 long inclusive of the conspicuous narrow petiole ; the blades 

 round-oval and round-obovate, very obtuse, thin, veinless or 

 nearly so, white beneath, thinly and shortly silky above and 

 rather permanently so ; flowering stems of pistillate plant 

 7 to 9 inches high, very slender and with small spreading 

 bracts ; heads small, in a terminal corymb of 5 to 7; involucres 

 campanulate, the scales all narrow and acuminate, very num- 

 erous and much imbricated, none but the innermost showing 

 slender white tips, the outer with hardly a trace of them : 

 staminate plant not known. 



Near Whitestown, Oneida Co., N. Y., by Dr. J. V. Haberer, 

 4 June, 1904, who reported it as growing on the border of a 

 piece of sandy woodland. No other species is known to me of 

 which the involucral scales are so narrow, and so almost 

 wholly green ; though the large A. mesochora of the prairie 

 country makes a near approach to this in that particular. 



The succeeding are subalpine, and of the Pacific Coast : 



AnTEnnaeia pdi,chei<I/A. Rigidly suffrutescent, depressed, 

 forming a loose mat, the surculi short, very leafy at the ends ; 

 leaves less than J^ inch long, obovate-spatulate, obtuse or 

 even retuse, more commonly acutish, of coriaceous texture 

 and permanently white-tomentose on both faces : flowering 

 stems very slender but hard and wiry, their few bracts small
