"It is a plant somewhere between the mosses and the lichens in its character it is one of the liverworts, and they are some of the first plants to go in advance of superior vegetation. This is called Marchantia." "And is it wonderful, Dr. Sandford?" "If I could show it to you, you would think so. Look here, Daisy on the surface of this leaf do you see little raised spots here and there?"
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.
Thus, Arethusa, Cypripedium, Pogonia, Calopogon, Spiranthes, Festuca, Osmunda, Onoclea, Lycopodium, Polytrichum, Bryum, Marchantia, Usnea, Parmelia, Cladonia, Agaricus, Chondrus, and perhaps a few other genera, furnish plants so familiar and so striking that a child will be sure to inquire concerning them, and a general description could easily be framed in a few words which could not mislead him concerning them.
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.
"Would it be violently against your principles?" "I do not want pay, Dr. Sandford." "Not if I were to offer to give you a sight of those little baskets on the frond of the Marchantia?" Daisy's face all changed; but she said in the quietest manner, "Can you do that, Dr. Sandford?" "Come with me." He held out his hand, which Daisy willingly took, and they went upstairs together.
At the island of Amsterdam, tufts of lycopodium and marchantia have been seen in places where the heat of the soil was far greater: such is the effect of an habitual stimulus on the organs of plants. The waters of Mariara contain no aquatic insects. Frogs are found in them, which, being probably chased by serpents, have leaped into the funnels, and there perished.
With a good deal of difficulty, Amabel was hoisted up, and planted her big feet in Jan's hands. It was no light pilgrimage for poor Jan, as he climbed the winding path. Amabel was peevish with weariness; her bundles were sadly in the way, and at every step a cup-moss or marchantia dropped out, and Amabel insisted upon its being picked up.

"Liverwort. Its name is Marchantia." "This liverwort; I never should have supposed it was anything but pretty, and of course good for something; but now I never heard anything so wonderful." "More than the sun?" said Dr. Sandford, smiling. "It is more surprising, I think," said Daisy. "Pray, what makes you conclude so securely that this little Marchantia is good for something?"
And looking through this, you will see what you could not see with your two eyes alone; there are some strong magnifying glasses here and I found to-day some plants of Marchantia growing in a sheltered place. Here is one of the baskets for you " "Is it on that bit of green leaf?" "Yes, but you can see nothing there. Try this view."
