  Liverworts

The single bryophyte (Phylum Bryophyta) which grows in the Singapore mangrove forest substrate is a liverwort. More about why bryophytes are scarce in mangroves.

Liverworts were named after the liver based on the species which resembled that human organ (with a heavy dose of imagination!) Such names had a utilitarian function in medieval times in Europe, because the herbalists (equivalent to the medicine man in other cultures) believed in the 'Doctrine of Signatures' which held that if a plant resembled a body part, it was useful for treating that part. We now know that this belief is invalid.

Liverworts are simple plants which lack the tissues for transporting water and food found in the other plants as well as other distinguishing characteristics.

There are other liverworts which grow on the branches or trunks of mangrove trees but these are rare.

Mangrove Liverwort
Lepidozia mamillosa
Class Hepaticopsida, Family Lepidoziaceae


Malaysia, Borneo, New Guinea. Locally, in some northwestern sites. Resembles small rnosses but there are none of these in mangrove areas; stems green, branching, growing flat with the tips raised; leaves stalkless, somewhat oblong, in two rows on either side of each stem, somewhat horizontal. On the muddy substratum or mud-lobster mounds. No known economic value. Rare.
