sharply serrate divisions, dark-green, densely and coarsely pubescent beneath, less densely 
so above; uppermost leaf-blades sessile and 3-cleft; flowers cymose in small clusters 
near or at the ends of the branches, nearly sessile; hypanthium strigose, urceolate, about 
1.5 mm. long; bractlets lanceolate, about 0.5 mm. long, acute, as long as the sepals and 
slightly narrower; stamens 2, short; pistils 2-4; achenes ovoid, acute, somewhat com- 
pressed.

3. Lachemilla procumbens (Rose) Rydberg. 
Alchemilla procumbens Rose, Contr. U. S. Nat. Herb. 10: 96. 1906. 
Cespitose perennial, with many creeping stems, which are 1-4 dm. long, rather spar-

adnate to the petioles and united around the stem; petioles 5-10 mm. long; leaf-blades 
more or less leathery, dark-green and glabrate above, paler and sparingly strigose beneath, 
deeply 3-parted to near the base, the lateral divisions usually again deeply 2-cleft ; divi- 
sions obovate-cuneate to spatulate, 1-2 dm. long, rounded at the apex, coarsely crenate 
above the middle ; inflorescence cymose, the branches usually more or less spreading, or 
more racemiform and with ascending branches; hypanthium open-campanulate, about 1.5

herbaceous above-ground stems 2-6 cm. high, sparingly strigose; lower leaves petioled; 
stipules connate and adnate to the petioles, 2~4-cleft into linear divisions; petioles of the 
lower leaves strigose, 3-4 mm. long; leaf-blades 3-parted to near the base; the lateral 
divisions sometimes 2-cleft; divisions 3-7 mm. long, cuneate, glabrous or sparingly strigose 
beneath, dark-green above, paler beneath, at the apex cleft into 3-7 linear or oblong divi- 
sions ; flowers in small terminal cymes; pedicels 1-5 mm. long; hypanthium campanulate, 
strigose, scarcely 1 mm. long; bractlets and sepals strigose, the former lanceolate and 
shorter than the ovate, obtuse or acutish sepals; filaments one half as long as the sepals;

5. Lachemilla Schiedeana Rydberg, sp. nov.

Erect perennial; stem 2-4 dm. high, rather simple, hirsute with ascending hairs; 
lower leaves petioled, the upper sessile; stipules connate and adnate to the petioles, often 
1cm. long, divided into linear or lanceolate lobes; leaf-blades divided to the base into 3 
divisions, the lateral ones of the lower leaves usnally deeply 2-cleft as in L. procumbens ; 
divisions cuneate or oblanceolate, dark-green, hirsute-strigose on both sides or glabrate
