102 Rhodora Max 
branches often 4 or 5 dm. long. It has 7-9 cauline leaves, the upper- 
most with subulate or involute tips; its heads are more numerous 
(3-9) and its glandular-viscid involucres have more definitely imbri- 
cated bracts. 
Various cordilleran species, A. wmbrinella Rydberg, A. pulvinata 
Greene, etc., are related to A. Pease; but I am unable to find any 
specles to which it can be satisfactorily referred. 
10. A. susviscosa Fernald. Fie. 10. Plant densely humifuse, 
the trailing branches subligneous, often 4-5 dm. long; stolons very 
short and crowded: leaves of the rosettes spatulate, obtusish, scarcely 
mucronate or with a very short mucro, 0.5-1.5 em. long, 2-5 mm. 
broad, densely white-tomentose: flowering stems 0.5-1.5 dm. high, 
white-tomentose throughout, glandular-hirsute above: cauline leaves 
7-10, tomentose; the lower linear-oblanceolate, mucronate, 1.5-2.5 
em. long; the upper linear-attenuate, with a subulate or involute sub- 
scarious pubescent tip: pistillate heads 3-9, densely or loosely corym- 
bose: involucre turbinate-campanulate, 5-6.5 mm. high: bracts about 
3-seriate; the outer 3-4 mm. long, oblong, subherbaceous, greenish 
or stramineous, often rose-tinged, glandular-viscid, with a thin obtuse 
cream-colored or rose-pink tip; interior narrower, acutish: corollas 
3.8-4.3 mm. long: achenes papillose, 1-1.2 mm. long: longer pappus- 
bristles 4.5-5 mm. long: staminate plant unknown.—Ruopora, xvi. 
131 (1914).—Cold north-facing limestone sea-cliffs east of Bic, 
Rimouski Co., QuEBEc. Fl. July. 
11. A. rsoLEPIS Greene. Fic. 7. Humifuse, the leafy stolons up 
to 7 cm. long: rosette-leaves oblanceolate or obovate, subacute or obtuse, 
short mucronate, 0.8—2.5 em. long, 2-7 mm. broad, densely white-tomen- 
tose above: flowering stems 0.7-2.5 dm. high, flexuous: cauline leaves 
9-18, linear-oblanceolate, tomentose, 1.5-3 em. long, 2-4 mm. broad; 
the lower with subulate tips; the 5-8 upper with broad flat scarious 
tips: heads 5-9, corymbose: pistillate involucres 6-8 mm. high: 
bracts of about 3 lengths, fuscous except for the oblong erose white or 
whitish widely spreading petal-like tips: corollas 3-3.7 mm. long: 
achenes sparingly papillose, 1-1.2 mm. long: longest pappus-bristles 
4.5-5.5 mm. long: staminate plant unknown.—Ottawa Nat. xxv.
