Of this curious genus there is one,* perhaps two species, in the Mexican collection of Andrieux, from which
the excellent Endlicher has derived his character of the Genus Antigonon, and which he has rightly placed
next to Brunnichia, in the order P olvgoneæ, Trib. I I I . “ Polygoneoe spurioe." Indeed all the three are so
closely allied, that they may possibly constitute but one species, the oniy striking difference I can find being
that Anclrieux's speeimens (which are not very perfect) have singularly dilated footstalks to the leaves. In
the n. 117 of Andrieux, there is, on each side of the stem, at the base o f the petiole, a rather large transverse
stipule ; but in the other specimen, or species, the base of the petiole is continued merely in the form of a
slightly elevated line all round the stem, as in our plant. Perhaps the stipules themselves have been very
early deciduous. In our specimen, again, there is a slight difference in the flowers, which have three outer
leaves of the perianth considerably larger than the rest ; and there are three inner ones, of which one is generally
abortive. Our fruit, though fully formed in appearance, contains only an imperfect seed.

The flowers seem to b e all female, and we are doubtful to what genus of Laurineoe of Nees von Esenbeck
this should be referred. That author, indeed, places it in Nectandra, but he had not seen the flowers. We
are rather disposed to refer it to his section Oreodaphneæ, and probably it may come under Ocotea, as
now circumscribed by Nees.
There are specimens of two other Laurineoe in tbe collection, one belonging to the Cinnamomum tribe.

H a b . Talisco.—Apparently a distinct species from any hitherto described. The leaves about two inches
long, and the same in breadth. The lip of the flower is nearly an inch long, about equal in length with the
tube, suddenly bent back, clothed on the upper side witb fleshy club-shaped appendages.
