CANADIAN RANUNCULACI'ÎTR. 29 



Section 3. — Involucre more or less resembling the leaves, usually distant from the 

 flower. Achenia without tails. 



1. — Anemone Hepatica, Linnceus. 



Plant aculescent ; leaves numerous, all radical, (from a tufted rhizome), long-stalked, 

 lamina of three rounded obtuse lobes (slightly overlappiug) with entire margins, the lateral 

 lobes occasionally bi-lobed. Flowers many from the same root, on separate stalks ; invo- 

 lucre three-leaved, so close to the flower as to resemble a true calyx. Sepals six (in two 

 rows), varying in number to nine (in three rows), petal-like, elliptic-oblong, tliose of the 

 outer row alternating with the approximating involucral leaves, size and coloiir variable, 

 (white, rose, purple, blue). Stamens usually from eighteen to twenty-one. Carpels nor- 

 mally about twenty-seven. There is an apparent circle of hairs between the involucre 

 and the outer row of sepals, similar to the pubescence of the rest of the scape, bixt nothing 

 between the sepals and stamens to represent petals. The inner verticil of sepals might 

 be regarded as petals were it not for the numerous examples in this order of the absence 

 or abnormal form of petals. Leaves, and especially the petioles and ilower-stalks, also 

 the external surface of thi^ involucral leaves, covered, more or less, with silky pubescence, 

 which becomes less conspicuous on the lamina as the foliage matures, and ultimately 

 disappears on its upper surface. Achenes hairy, collapsing so as to become furrowed.
