One of the most abimdant plants in the Falkland Islands, growing with Empetrum rubrum. It appeai-s to
migrate northwards from the Strait of Magalhaens as fai* as Maldonado on the easteni, and Chüoe on the western
coast of South America.

Apparently a rare species, for I have seen it from no other part of Fuegia and Patagonia, or collected by auy
other natinalists but those mentioned above. The whole plant is much larger thau B. Magellanica, and not viscid
the leaves ai-e sinuato-lobate towai'ds the summit, opaque, and often turn black in di'jing ; in other respects it is very
near it.

This is the “ Madi” and “ Melosa” of the Chilians, who extract an oil from the seed, for which purpose it is
cultivated abundantly both in that country and in other parts of America.

A very inconspicuous plant, allied to Ceratella and Trineuron of the ‘Flora Antarctica’ (Pt. 1. p. 24.), and
also to an unpublished Tasmanian genus. I t is easily recognized by the curious scarious margins of the leaves,
wliich are broad and bifid at the apex,

Some observations on these specimens are in the work quoted above. The species is found on the American
continent, and is one of the few plants common to Lord Auckland’s Group and Kerguelen’s Land which do not
exist in Puegia.

One of the most variable and abundant of South American plants, from the latitude of Quito to the Falkland
Islands, also occuning iu Brazil.
I am inclined to consider the G. spicatum as the tj-pical form of a species to which G. Amerlcanuin, G. purpu-
reimi, G. Pennsglvanicum. (?), and probably several other North American forms should be refen-ed, and from winch
they differ no more than do G. strictum, Noi'vegicum, &c., from the G. sylvaticum of Eui'ope. Authentic specimens
of G.purpureum, which I have studied, are preser\-ed in the British Museum, with DiUenius’ haud-wi'iting
attached to them, and they accord perfectly with the figure iu ‘ Hortus Elthamensis.’ The plant is common in
the midcUe and southern states of North America, and is very eridently a variety of the foUoiving, G. Ameii-
camm, which is generaUy more branched, ivith broader leaves and the inflorescence more elongated. I t is a species
of California and the southem United States, whence I have examined indiriduals with the wooUy substance
as appressed to the stem aud under side of the leaves as in many Chilian ones of G. spicatum. Bertero’s Chilian
specimens of G. Berterianuni arc apparently G. purpureum, between which and G. falcattim (through the
varieties of the latter plant enumerated iu De CaudoUe’s ‘ Prodi'omus’) there seems very little tangible specific
difference.
An examination of copious suites of specimens of De Candolle’s spicate group of Giaphallnm certainly rather
tends than otherwise to the union of about sixteen species which it contains (as conjectm-ed by Hooker and Arnott
ill the ‘ Botanical Jom-nal ’), and to reduce them to perhaps two, one of them, G. sylvaticum, being Em-opean, and
the other (of which G. spicatum is the tjqte) American. GeneraUy speaking, the two forms, of the old and new
world, are sufficiently distinguishable by the eye, though I should feel it difiicult to give a definition of either that
would include all states of one and exclude aU of the other. If future observations confirm tliis supposition
a question wiU arise respecting the specific name; the oldest, or Linnæan {G. purpureum) applying to the
variety, if that be called variety whicli is the less developed state of a plant more widely diffused under another
form. The trivial appeUatioii of G. spicatum, again, though not botanicaUy speaking strictly correct, is characteristic
of aU the aspects of both the European and American plants, and that of G. Amoicamm appears even
more suitable to a plant so particularly abundant in both divisions of the new world.
