130 Rhodora [Jur 
Dwarf, 3-4.5 em. high, monocephalous, humifuse; the assurgent 
stolons very short, not perceptibly elongated: basal leaves oblanceolate, 
mucronate, S-14 mm. long, 2.5-3.5 mm. wide, glabrous or glabrate 
above, loosely lanate or glabrate beneath; the cauline about 9, crowded, 
linear-oblanceolate, 6-14 mm. long, lanate beneath, glabrous or gla- 
brate above, with a lanceolate or narrowly deltoid glabrous flat scarious 
tip 1.5-2 mm. long: pistillate involucre hemispherical, 7 mm. high, 
12-13 mm. broad (in the dried specimen), lanate at base: bracts in 
about 5 series, clearly imbricated, oblong, obtuse; the outer fuscous, 
with a short stramineous tip; the inner with a long obtuse stramineous 
tip.— LABRADOR: without definite locality, coll. by members of the 
Unitas Fratrum (Tyre in Gray Herb.); Okkak, Weitz. 
Related to 4. alpina, var. monocephala (DC.) T. & G. and to A. 
glabrata (Vahl) Greene, but differing from both in the conspicuously 
imbricated involucre with obtuse paler bracts; those two boreal plants 
(both occurring also in northern Labrador) having the linear-attenuate 
braets uniformly dark-colored and of nearly equal length. It is note- 
worthy that this involucral character of 4. pygmaea was recognized 
by Steetz, who, upon one of the specimens made the note: “ Dis- 
tinguitur facillime a varietate monocephala Ant. alpinae: involucri 
squamis interioribus obtusis, scariosis, nec acuminatis, coloratis." 
A. pygmaea is the plant referred to by Gray, in the Synoptical Flora, 
as A. carpatica, "a monocephalous form!" In its small rosettes of 
leaves and its involucre, it is, however, quite unlike A. carpatica or 
any of its known allies. 
A. straminea, n. sp., planta humifusa, stolonibus foliosis perbrevi- 
bus vel paulo elongatis (ad 7 cm. longis); foliis basilaribus spathulatis 
subacutis vix mucronatis 5-12 mm. longis 2-4 mm. latis supra albidis 
tomento denso minutoque; caule florifero 3-14 cm. alto gracile remote 
folioso; foliis caulinis 8-10 linearibus 6-14 cm. longis 1-2 mm. latis, 
mediis attenuatis apice subulato fusco, superioribus apice lineari 
scarioso; capitulis femineis 1-7 plerumque dense corymbosis hemi- 
sphaerico-campanulatis basi rotundatis; involuero 5.5-7 mm. alto 
4.5-8 mm. lato (in specimine siccato); bracteis 4—6-seriatis valde 
imbricatis, exterioribus ovatis vel oblongis brunneis basi paulo lanatis 
apice tenue chartaceo stramineo obtuso vel subacuto, mediis oblongis 
apice deltoideo obtuso vel subacuto stramineo, interioribus apice 
lanceolato eroso stramineo; achaeniis glabris; stylo flavescente deinde 
brunneo. 
Plant humifuse, the leafy stolons very short or slightly elongated 
(up to 7 em. long): leaves of the rosettes spatulate, subacute, barely 
mucronate, 5-12 mm. long, 2-4 mm. broad, white above with dense 
fine tomentum: flowering stem 3-14 em. high, slender, remotely 
leafy: cauline leaves 8-10, linear, 6-14 mm. long, 1-2 mm. wide;
