In the Marchantia polymorpha some yellow wool proceeds from the flower-bearing anthers, which moves spontaneously in the anther, while it drops its dust like atoms. Murray, Syst. Veg. See note on Collinfonia for other instances of vegetable spontaneity. Corallinus, or lichen rangiferinus. Coral-moss. Clandestine-marriage.
In the grass where, after lying down for a moment, I had caught these lice were a few plants in blossom, of which the most abundant were three composites: Hedypnois polymorpha, Senecio gallicus and Anthemis arvensis.
Especially significant is the structure of such intermediate types as the Liverworts. Beyond the differentiation of the covering cells from the contained cells, and the contrast between upper surface and under surface, the frond of Marchantia polymorpha clearly shows us the direct effect of incident forces; and shows us, too, how it is involved with the effect of inherited proclivities.
The basaltic columns, which compose the Giants Causeway on the coast of Ireland, as well as those which support the cave of Fingal, are evidently of volcanic origin, as is well illustrated in an ingenious paper of Mr. Keir, in the Philos. Clandestine Marriage. Conserva polymorpha. This vegetable is put amongst the cryptogamia, or clandestine marriages, by Linneus; but, according to Mr.
There is another plant, Medicago polymorpha, which may be said to assume a great variety of shapes; as the seed-vessels resemble sometimes snail-horns, at other times caterpillars with or without long hair upon them; by which means it is probable they sometimes elude the depredations of those insects.
Figs wounded with a straw, and pears and plumbs wounded by insects ripen sooner, and become sweeter Female figs closed on all sides, supposed to be monsters Basaltic columns produced by volcanoes shewn by their form Byssus floats on the sea in the day, and sinks in the night Conserva polymorpha twice changes its colour and its form Some seed-vessels and seeds resemble insects

YELLOW MEDIC. Is nearly allied to Lucerne, and is equally good for fodder; it will grow on land that is very dry, and hence is likely to become a most useful plant; its culture has, however, been tried but partially. Some experiments were made with this plant by Thomas Le Blanc, Esq., in Suffolk, which are recorded by Professor Martyn. Martyn's Miller's Dict. art. Medicago. MEDICAGO polymorpha.
