 to 2o inches high. Flmvcrs, minute, with yellowish petals. 

 Leaves small, \ inch long, roundish or heart-shaped, the upper 

 ones inclining to lance-shaped. 



This modest spearwort will escape our notice, hidden under 

 larger and more aggressiv'^e growths, unless we are determined to 

 find every treasure which the marshy ground contains.

Trollius laxus. — Family, Crowfoot. Color, white or green- 

 ish yellow. Leaves, alternate, palmately divided. Time, May. 



Sepals, 5 to 6, petal-like, with a whitish or yellowish color. 

 Petals, small, numerous, shorter than the many stamens, in- 

 dented near the base. Fruit, several sessile pods. Flow- 

 ers, single, terminal, about 2 inches across, not globe-shaped, 

 as its name implies. Stems weak, slender, i to 2 feet long. 



5. Three-leaved Gold-thread 



Copiis trifb/ia ("to cut," alluding to the divided leaves). 

 — Family, Crowfoot. Color, white. Leaves, from the root, 

 3-lobed, the leaflets sharply toothed, shining, evergreen.

Sepals, 5 to 7, falling early. Petals, same number, club- 

 shaped, small, brought together, and hollow at apex. Sta- 

 mens, numerous. Pistils, 3 to 7, stalked. Flowers on leafless 

 scapes, not conspicuous.

 bog-mosses, and are bright and shining the summer through. 

 The "gold-thread" appears when we dig up the root and find it 

 composed of long, yellow fibres.
