(1803), at least as to name-bringing synonym. By Michaux the name 
Lechea major was applied to a true Lechea, now known as L. villosa 
Ell. Sk. i. 184 (1816). Elliott, when renaming the species, remarks: 
“As the L. major of Linnaeus is now understood to be the Cistus 
canadensis and not a Lechea, I have avoided the name to prevent 
confusion.” At about the same time attention was also called to the 
identity of the two names by Smith in Rees’s Encyclopedia (xx. no. 2 
(“1819”)): “Now it happens that the specimen in the Linnaean 
Herbarium [of L. major] is no other than Cistus canadensis.” The 
sheet in the Linnaean Herbarium to which Smith refers bears three 
fruiting branches of H. canadense, but no data. The name Helian- 
themum canadense (L.) Michx. is employed by Elliott for the species 
(Sk. ii. 4 (1824)) and should according to the International Rules con- 
tinue to be used for the plant, although Lechea major has page priority 
over Cistus canadensis. 
For the plant to which Mr. Bicknell, when first drawing attention 
(Bull. Torr. Club xxi. 257-260 (1894)) to the differences between 
our two previously confused northeastern species, applied the name 
Helianthemum majus, the first available name seems to be HELIAN- 
THEMUM PROPINQUUM Bicknell in Britton, Man. ed. 2. 1069 (1905)). 
This was published as a new species intermediate between H, majus 
(of auth.) and H. canadense, and is still upheld by Mr. Bicknell (Bull. 
Torr. Club xl. 615 (1913)) as distinct, but I am unable, after careful 
comparison of five good sheets of material showing all stages of growth, 
collected by Mr. Bicknell and now in the Gray Herbarium, to discover 
any characters which seem to justify the separation of the plant 
as a species distinct from the H. majus of our present-day manuals — 
a conclusion in which I have the support of Prof. Fernald, who has 
previously worked on the group. Dr. Britton’s reference (Ill. Fl. ed. 2. 
ii. 540 (1913)) of H. propinquum to H. georgianum Chapm. is not 
supported by the Gray Herbarium specimens referred to the latter 
species. :
