MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. II9 



SANTALACEAE. 



Comandra pallida A. DC. Prod. 14: 6^6 [Man. R. M. 324; 111. Fl. 



I : 536; Bot. Cal. 2 : 104]. 



On plains and hillsides up to an altitude of 2000 m. It produces 

 rootstocks a couple of meters long ; I doubt if the plant is really 

 parasitic. 



Montana: Bridger Mountains, June 12-16, 1897, Rydberg & 

 Bcssey, jgjg, jg^o and 3941 ; Spanish Basin, June 23 and 24, 3Q42;

 Eriogonum flavum Nutt. Eras. Cat. 1813 [Man. R. M. 314; 111. 



Fl. i: 545; Wats. Rev. 256].* 



On dry plains and hills up to an altitude of 1500 m. 



Montana : Cottonwood Creek, 1896, Flodman, 3S0; Great Falls, 

 1891, R. S. Williams^ 121 ; Fort Benton, Jo/111 Pcarsall, 1033 ; Six-

* Eriogonum androsaceum Benth. ; DC. Prod. 14: 9 [Wats. Rev. 



256]. 



Nearest related to R. flaviciii, but much smaller, dwarf, with yellow, 

 sparsely villous, short-attenuate flowers. Mainly in alpine regions of 

 British America, but the following specimens were collected within 

 our range : 



Montana: Upper Marias Pass, 1883, Caiibv, 2^3. 



* Eriogonum polyphyllum Small. 



Perennial, dwarf, tufted. Stems stout, simple or sparingly 

 branched, 1-3 cm. long, clothed with the persistent very densely 

 packed leaves, thus appearing 1.5-2 cm. thick; leaves numerous ; 

 blades spatulate or oblong-spatulate, 1-2 cm. long, obtuse, woolly 

 on both sides, more or less revolute, narrowed into short petioles ; 

 scapes erect, one or several together, 1-5 cm. tall, topped by a head 

 of usually 2-4 sessile or short-peduncled involucres, woolly like the 

 leaves ; bracts similar to the leaves but smaller, often surpassing the 

 involucres, drooping in age ; involucres becoming turbinate, about 5 

 mm. high, rather delicate, with both triangular and rounded teeth : 

 calyx deep yellow, sometimes tinged with red, 3 mm., becoming 5
