clothed with whitish hirsute hairs mostly deflexed; leaves lance-

 uppermost pairs quite sessile, all very thin, triple-nerved, re- 

 motely and not prominently dentate, nearly glabrous on both 

 faces; heads small, many, somewhat pa'nicled and the panicle 

 leafv-bracted; involucre broadly campanulate, the 16 to 20 bracts 

 lanceolate, ol)tusish, thin, sparsely hirsute below the middle; 

 ravs many, narrow and not long; disk-corollas with soft-villous

Trail, British Columbia, J. M. Macoun, 22nd June, 1902; ^

A. STRiCTA. Erect from a horizontal rootstock, nearly 2 feet 

 high, sparinglv leafv, v/ith a pair of branches from each pair of 

 cauline leaves, these very erect, pedunculiform, nearly parallel 

 with the main stem, all glandular-puberulent ; basal leaves few, 

 cuneate-oblong, obtuse, 4 inches long or more, including the S 

 indistinctly petiolar base, 3 -nerved, very remotelv or not at all 

 dentate, the veins and margins scaberulous, otherwise glabrous; 

 heads 9 to 1 1 each at the end of a long peduncle, those of the 

 branches surpassing the terminal one; involucre campanulate, 

 3/^ inch high, of about 12 lanceolate thin glandular, but scarcely 

 hairy bracts; rays 8 or 10, long, deep-yellow; disk-corollas with 

 long slender tut)e hirtellous with strongly gland-tipped short

British Columbia, along the International boundary, 

 between the Columbia and Kettle Rivers, J. M. Macoun, 30th 

 June, 1902. A fine species of that section in which Pursh's 

 A. fulf^ens is tvpical, all the others of which section are mono- 

 cephalous, while this new one produces a flowering peduncle 

 from each leaf-axil, yet in habit the plant is as upright and strict 

 as a plant can well be that is not simple. The label of my ^ 

 specimen bears No. 64979 of Canad. Geol. Surv. 



A. LACTUCiNA. Slender, a foot high or less, the herbage of a 

 vivid green and almost whollv glabrous; basal leaves not seen, 

 the cauline is about 2 pairs, sessile and divaricately spreading, 

 the lower pair either panduriform or else contracted very near 

 the base to a broad and short winged petiole, the upper pair 

 often broadest at base and there subhastately dilated; all very 

 acute at apex, below the middle more or less prominently and 

 even spinosely toothed; heads small and -subcorymbose. the 

 involucres campanulate, of about 10 narrow bracts slenderlv 

 acuminate, not pubescent , but granular-glandular; rays 10 or 12,
