30 LAWSON" : REVISION OF THE 



Eocky woodlands west of Brockvillo, not rare ; and Ottawa, lot 0, rare. — B. Billings jr. 

 Penetanguisheue, Lake Huron, in flower 25th April.— C. C. Todd. Ottawa (not so com- 

 mon as A. acutiloba). — Maroun. Petit Cap St. Joachim. — Provancher. From Isle of Orleans, 

 westward, rather rare in Quebec Province. — BruneL St. Stephen, N.B., in 11. May 10, 1879. 

 — Mr. Vroom. Keswick Eidge, N.B. — /. Moser. Windsor, N.S., rare. — Prof. Hoi/y. Pictou, 

 N.S., A^ery rare.— ^. H. McKaij. Bridgewater, N.S.— i?ey. E. Ba!/. Siika.—Rolhrock. 



In woods in the central limestone tracts, from Canada to lat. 52°. Mr. Drummond found 

 it as far north as lat. 55", in the secluded alpine valleys on the eastern declivity of the 

 Eocky Mountain ridge. — Richardson, in Hook., Fl. B.-A. (Doubt has been expressed 

 regarding the Winnipeg and Eocky Mountain habitats, yet Eothrock reports the plant 

 from Sitka.) 



Sir William Hooker stated (Fl. Bor.-Am., I., p. 9, 1833) that there could be no question 

 of the identity of the American and European iiulividiials of this species, but, in view of 

 the increased imi)ortan((' of .studying carefully the relationships of forms that liaA^e been 

 long geographically separated, it would be worth wliil(\ when opportunity offers, to 

 compare carefully the American with the European forms, especially in a state of culti- 

 vation, which might possibly throw more light ou their relations than we now possess. 

 Meutzelius (1682) enumerates doiible-flowered, white-flowered and red-flowered varieties; 

 many double-flowered varieties, origiiuiting from the European ]ilant, have been long 

 in cultivation. De Candolle (Syst. Nat.) distinguished the American plant from the 

 European one by its xMlose petioles and scapes. In the American plant, also, the sepals 

 appear to be smaller in proportion to the size of the leaflets of the involucre. 



Mr. Millspaugh (Bulletin Torrey Bot. Clul), XL, i>. 55) notices some abnormal indige- 

 nous forms observed at Binghamton, N.Y. : (1.) I'lants with deep blue sepals with a 

 white or light blue margin, all absolutely stamenless. (2.) Plants with pure white 

 flowers, all of these having nine sepals, and resembling the flowers of A. nemorosa. 



This species extends to Florida, ot-curring there in shady woods, where however its 

 near ally, A. acutiloba, is not known. " Hepaticas are amongst those plants of which the 

 seed will not germinate if dried and stored, but which will come up freely from the self- 

 sown seed, if the coudilions are favourable. After the flowering is over, the crown of the 

 p»lant should be sprinkled with fine peat soil, or some equivalent, until the base of the 

 leaf stalks is covered. Into this the seeds fall, and about the time that active growth 

 commences in the parent plant in autiimn, they germinate, producing a pair of leaves 

 simultaneously with the growth of the new leaves on the old plant. When the leaves 

 are fully developed, the seedlings may be removed. Some flower the next year. They 

 generally follow the colour of their parent, though pink seedlings occasionally come from 

 blue plants. More seedlings come up amongst the leaves than outside them." (Eev. C. 

 Wolley Dod, Gard. Chro., Feb. 16, 1884.) 



2. — Anemone acutiloba, Lawson. 



Eesembles the preceding ; the leaves are even more symmetrical in shape, but the 

 lobes or segments are elongated-tapering, gradually narrowed from below the middle to 

 an acute point. The iuvolucral leaves and sepals are also more or less acute. Flowers in 

 May. So far as observed, intermediate forms do not occur.
