ACCESSIONS TO ANTENNAEIA. 151 



Antbnnaria densa. Plant forming mats, the whole rising 

 little more or less than an inch above ground ; stolons reduced 

 in the main to sessile fascicles of small leaves crowded upon the 

 short stout branches of the subligneous caudex ; leaves hardly 

 K inch long, obovate, rather loosely and softly white-woolly 

 on both faces ; those of the short flowering stems oblong, 

 almost imbricate-crowded : heads of fertile plant 1 to 4, sessile ; 

 the short-herbaceous part of involucral scales concealed by 

 wool, the ample tips of a dark olive-green or almost blackish, 

 those of the outer series rather obtuse, all the others acutish : 

 sterile plant not known. 



Alpine on Mt. San Gorgonio of the San Bernardino Range, 

 southern California, at 11000 feet, collected and distributed 

 by lye Roy Abrams and E. H. McGregor, 12 July, 1908. It 

 was sent out for A. media, but its nearest ally is perhaps 

 A. pulvinata of the frigid steppes of a thousand miles north- 

 westward. 



Antbnnaria Candida. Densely matted but not as low as 

 A. densa, the numerous very leafy surculi upright and their 

 leaves not rosulate but suberect, J^ inch long more or less, 

 obovate-spatulate, clothed densely with close snowy-white 

 tomentum : flowering stems rising 1 to 2 inches above the 

 cushion of leafy surculi, slender and with their small leaves as 

 white-woolly as other parts : heads in fertile plant 3 to 5, 

 closely congested ; proper scales of involucre wholly concealed 

 by the white indument, their translucent tips from oval and 

 obtuse in the outermost to oblong, and in the innermost to 

 lanceolate and acute or acuminate : sterile plant not known. 



Detected at 9000 feet on Mt. Rainer, Washington, by Mr. 

 O. D. Allen, 14 Aug., 1895, and distributed to U. S. Herb, 

 under n. 141. At variance with everything else that has been 

 called A. media by its peculiarly congested habit, upright firm 

 foliage, and the shining whiteness of the indument investing 

 all parts except the dark tips of the involucral bracts. Its next 

 of kin is A. pulvinata.
