The Species of the Genus Larix. 99 
p. 645). According to the title-page, he relies upon "twelve 
, 
years travels and residence in that country”, and, describing 
L. pendula, Lambert, and L. microcarpa, Lambert, jointly, 
he says positively that MicHaux is mistaken in including 
them under one species, adding: “I never saw them both 
growing in the same place, or even near one another.” We 
have, nevertheless, no doubt at all, that this is wrong, and that 
his remark considers only L. laricina, the occurrence of which 
in two forms is due in the main to the different characters 
of the growth localities. The description of the two “species”, 
as far as it concerns their habitats, sounds extremely im- 
probable. L. pendula is said to be “a beautiful tree, res- 
embling the European Larch”; and grows “in low cedar 
swamps”, while L. microcarpa, which certainly “resembles 
the preceding L. pendula” has its home “on high mountains”. 
Finally, L. pendula — which must, at any rate have been 
less common than the other, as no subsequent attempts 
to find it in North America have been successful — has 
been provided with American popular names (Tamarack, 
Hackmatack), no American name being given to L. micro- 
carpa (laricina), which otherwise is known under these 
names. As already mentioned, we have no doubt that there 
is only one species of larch of that group in North 
America, and that Pursn’s description is clearly influenced 
by LamBert’s account (in Genus Pinus, 1803), in which 
two “species” are mentioned, but which, in part at all 
events, is based upon material from specimens cultivated 
in England. 
In SOLANDER’s Notes (Brit. Mus., unpublished), its habitat 
is given as follows: — ,,Habitat in New Foundland insula 
Amer. septentr. Latitud. 48 gr. ubi hiems perquam aspera”, 
but in SOLANDER's description in Arron: Hort. Kew., there
