cerinthoide», Br., as having this structnre, and it is a singular circumstance that these two plants, which, through
their bilocidaj- anthers and hypogynous fflameuts, completely rmite iU Erícete of the northern hemisphere with their
southern representatives in Australia, the Epaeridete, are hoth natives of very humid climates and densely wooded
regions, and not of such localities as the majority of cither Order thut especially the Epaerideee) affect.
The subscandent habit of L. Jm e r km m is very peculiar ; it grows on the tnmks of trees, and often creeps up
them for some feet. This is also the case with some other distichous-leaved Antarctic plants, as Callixene, and
Lusuriaga, and with the Prionotes and Becaspora of Tasmania.

I can hardly consider Mr. Darwin’s specimens to be even a variety of the plant collected hy Capt. King at
Cape Fairweather (not Port Jamaica, vid. Griseb.), on the coast of Patagoma.
Except the rather broader and more obtuse segments of the less deeply divided calyx, there is nothing to
distinguish this from the Tasmaman aud New Zealand G. montana, Porst.

This plant, the common Enghsh Bind-weed, is universally diffused throughout the temperate regions, both of

In size and habit this httle species closely resembles the M. Antarctica (Part 1. p. 67. t. 38), hut it is a much
slenderer, less rigid, and comparatively glabrous plant, with larger, though stfll very inconspiouous, and white
flowers. It evidently belongs, hy its prostrate stems and axihai-y flowers, to the New Zealand group o fth e genus,
which, under the species ahuded to. I have noticed as veiy different from that including the majority of the genus.

The ti-ue Potato plant reaches the boimdarj' to which the Antarctic Plora of South America is confined, and is
described as particularly abundant in the localities ivhenee Mr. Darwin’s specimens were brought. The nature of the
present work forbids my dwelhng on some of the peculiarities which mark the history and habitat of this plant ; and
I leave the subject with the less reluctance, because Mr. Darwin’s own history of its discovery m an mdisputably
native state is already pubhshed in one of the most interesting ‘ Jom-nals of a Naturalist ' that has ever been
written. The following remarks apply wholly to the botanical affinities of the individual species now universally
cultivated in all temperate civilized cotmtries.
There are in South America several Solana, so closely aUied to the true Potato, that it is exceedingly difficult
to distinguish them specifically. Though difl'ering materially in the shape of their calycme lobes, they display such
variation in these organs, that no specific value can be attached to them alone. The fruit may afford better characters,
but that of many is at present unkuowm. The following is an enumeration of those South American Solana,
allied to, or varieties of, the trae S. tuheromm, which exist in the Hookerian Herhai-ium. I shall commence with
the specimens most similar to the common cultivated form.
