(lat. 37°); also found on the Andes by Dr. Gillies, in lat. 33°, and on the mountains of Quito in Colombia,
imder the equator, by Professor Jameson, whose specimens appeal- to differ iu no respect from those gathered in
Fuegia.
The whole plant is generally perfectly glabrous, though not imfrequently a slight pubescence is observable
on the scales of the involucre in individuals collected in the Falklands and Fuegia. The A. Gilliesii is certainly not
distinct from this ; both have the flowers of the ray disposed in several series ; but otherwise, and especially in habit,
they agree better -uith Aster than with the following genus.

I quite believe the E. alpinns and var. uniflorus of Fuegia to be identical with the so-named species of Europe
and North America, but whether they may not be in both countries varieties of another plant, is more than doubtful.
Thus, in North America the E. alpinus passes at once and unequivocally into a species called E. glabratus, which is of a
totally different habit aud appearance, and unites the alpine plant with others of the United States. So, in Europe,
E. alpiiius of the Altai mountains becomes E. elongatus, in which the pappus is about one half longer than the
achænium, and that again E. glabratus, whose pappus is twice as long as the achænium. Again, I have seen
specimeus of this species from the SieiTa Nevada of Spain, alt. 8,000 feet, which are the common fonn of E. alpinus,
and a variety gathered at 1,000 feet of lower elevation, apparently the same as E. acris; both are named E. alpinus
by M. Boissier, a most accurate and learned European botanist. The individuals of this genus ai-e apparently in the
same predicament as those of Epilobium, a form from one country often constituting the link that unites two allied
ones of a remote region, insomuch that it is impossible to study the species properly without an- examination of
individuals from all parts of the globe. The rapidity with which an Erigeron may be dispersed and the consequent
facility the genus affords for presenting varieties, are evidenced by the spread of E. Canadensis, L., throughout the
warm countries of the old world, since the discoveiy of the new ; it is a plant which, requiiing much summer heat,
does not enter into the Antarctic regions, though abundant in Canada.
The variety y is possibly a distinct species, but my specimens are very imperfect, and the E. alpinus itself is so
variable in all the parts of the world it inhabits that this may be a state of it. Capt. King has what I consider an
intermediate variety from Cape Fairweather, on the coast of Patagonia, which in hairiness and foliage resembles
E. alpinus, but the capitula are, as in var. myosoiifolius, aggregated at the apex of the stem.

I have ventm-ed to separate this from the former because of its broad leaves and evident petioles, though I must
confess to having seen specimens from Switzerland of E. g ra n itp rm , Hoppe, a variety of E. aVpinm, which
the sliape of tho foliage very closely approaches this. It bears tho name of Capt. Sulivan, E.N., who during his
several visits to and survey of the coasts of the Falkland Islands, formed a very interesting botanical collection
wliich he has liberally placed in my hands for exammation.

An exceedingly variable species, affied to E. Canadensis, though with much larger capitula. The vai-, minor
was referred in the work quoted (under that variety) to E. Canadensis, hut I find no specimens of that species, either
European or North or South American, to vary much in the size of the capitula. The variety glaielliis, of Hooker
and -Àrnott, is, I think, certainly referable to E. alpinus.

This little species varies a good deal in size, from one half to three inches long ; the leaves are nearly entire
or sinuated, smooth or more or less hairy, sometimes almost hfrsute. Mr. Darwin’s specimens, from Wollaston
Island near Cape Horn, have haii-y scapes.
