tasmanian liverworts - jungermanniaceae

lophozia sp.

Lophozia sp.
1. habit

 

Lophozia species are predominantly a northern hemisphere liverwort with several species recorded from New Zealand. Only two species are reported for Tasmania, L. androgyna and L. tasmanica. Lacking a key to the species we have to make do with brief descriptions and temporary labels for the present.

Our first specimen (111127, pix 5-7) was relatively large with a stem diameter of 0.12 mm and had underleaves with teeth on the outside margins and 5-6 cells at base of underleaf lobes (pix 6). Leaf cells on the disks had 2-3 granular oil bodies. It was growing mixed with other bryophytes on a Nothofagus c. in the shade at an altitude of 750m.

The second specimen (120819B, pix 1-4) was a much smaller plant with stems a scant 30 µm across and had margins entire on the underleaves; this had only 2 cells at the base of underleaf lobes. There were 2-5(-9) granular oil bodies on the leaf disks. It was growing almost as a pure population on a Leptospermum tree a couple of hundred meters from where the first specimen was growing.

Engel & Glenny1 and Schuster2 discuss this genus extensively in their books but these have not been very helpful in determining the identity of local liverworts.
