What's the difference between liverwort and prothallium?
Liverwort
Definition:
(n.) A ranunculaceous plant (Anemone Hepatica) with pretty white or bluish flowers and a three-lobed leaf; -- called also squirrel cups.
(n.) A flowerless plant (Marchantia polymorpha), having an irregularly lobed, spreading, and forking frond.
Example Sentences:
(1) Clinical features, botany, phytochemistry, patch testing and ecology of Compositae and Frullania (liverwort) allergic contact phytodermatitis are discussed.
(2) Even the best nurseries will have a few plants with liverworts growing on their surface, because liverworts love damp, bare ground.

(9) This ORF is highly homologous to ORF513 found in the corresponding region of liverwort chloroplast DNA and ORF563 located downstream from trnT in Chlamydomonas moewusii chloroplast DNA.
(10) It is hoped the animals will recolonise the tarn and its surrounding streams, and play an important part in the ecosystem, grazing and burrowing into areas of the riverbank and allowing rare plants to grow, including mosses and liverworts that need patches of open habitat.
(11) The gene order around rpl16, 5' rpl22-rps3-rpl16, is identical to that detected in the chloroplast DNA of liverwort, tobacco and maize.
