68 THE Ottawa NATURALIST. [June 
almost invariably found growing on rotten trunks and stumps 
which had in part escaped the conflagration. 
The leaching of the surface soil, the gradual consumption of 
the alkaline constituents by the first growth, and the resulting 
addition of the necessary vegetable matter will, in a few years, 
prepare the burnt area for the pines, whose seeds are doubtless — 
wind-sown. Some such conditions seem to regulate the reappear- 
ance of the spruces also, and J once observed the Hemlock ( Tsuga 
Canadensis) re-occupying its old site after a period of ten or 
twelve years. 
BOTANICAL NOTE. 
Erythronium albidum. A nice specimen of this flower has 
been received from an anonymous correspondent, ‘‘E. U. O. M,” of 
Belleville, Ont., who states that the root was originally collected 
at Massassaga Point, Bay of Quinte, in 1896. Every year since 
one flower and two leaves only have been produced. The flower in 
this species is white, faintly tinged with violet or blue. It is smaller 
than the common American Dog’s-tooth Violet or Adder’s Tongue 
( Erythronium americanum) and the leaves are not prettily mottled 
with brown, as in that species. In Macoun’s Catalogue of Cana- 
dian Piants it is recorded that, although the species is apparently 
rare in Ontario, it was abundant in 1878 in a rich low wood two 
miles east of Belleville, between the Grand Trunk Railway and 
the Bay of Quinte. Dr. Burgess also found the species on steep 
clay banks of the River Thames at the ‘‘Cove,”” London, Ont.

BoTANICAL CLUB OF CaNnaADA.—The undersigned will be 
obliged to any botanists who have taken exact dates of the 
flowering of native plants in the Ottawa district this spring, if 
they will communicate to him, with a view of making the Ottawa 
Report to the Botanical Club as complete as possible.
