IV. SOME SENECIOS OF EASTERN QUEBEC AND 
NEWFOUNDLAND. 
(Plate 144.) 
SENECIO RESEDIFOLIUS.—In 1818 Ledebour described from the 
Altai of Siberia a monocephalous Senecio under the name Cineraria 
lyrata.. The plant was subsequently collected by Bunge, Fischer, 
Tiling, Turezaninow, Charles Wright and others in the Altai and 
Baikal regions or at other points in Siberia eastward to Amur and 
the coast of Bering Straits. It is a well marked but highly variable 
plant, a single variation of which was illustrated in Reichenbach’s 
Iconagraphia? In 1831 Lessing gave a beautifully detailed description 
of one of Chamisso's plants from Bay St. Lawrence or Gulf of St. 
Lawrence on the Asiatic side of Bering Straits as Senecio resedifolius,? 
and as a synonym he cited Cineraria lyrata Less., Lessing's specific 
name being unavailable on account of the older Senecio lyratus L. f. 
Gradually the knowledge of Senecio resedifolius was extended 
until, in 1867, Herder* recognized it as a wide-ranging species, extend-

3 Lessing, Linnaea, vi. 243 (1831). Lessing's account says clearly that the original 
habitat was “In sinu St. Laurentii cel. de Chamisso” and one of the original labels 
in Chamisso's hand, in the Gray Herbarium, is equally explicit: ‘“‘ Sin. St. Laurent. '' 
This, of course, is the well known Bay or Gulf of St. Lawrence on the west side of 
Bering Straits, where many types were collected by Chamisso. Greenman in his 
monograph (Ann. Mo Bot. Gard. iii. 99) erroneously cites the Chamisso material 
as coming from “Alaska: St. Lawrence Island, Chamisso. ”
