Radulaceae
Family: Radulaceae
Scientific Name | Common Name | Summary |
---|---|---|
Radula bolanderi | The leaves of R. bolanderi do not overlap, therefore the stem is visible. Radula lacks underleaves which distinguished this genus from Porella and Frullania. | |
Radula complanata | Radula species lack underleaves which distinguished this genus from Porella and Frullania. The leaves of R. complanata overlap and obscure the underlying stem. | |
Radula obtusiloba |
BFNA treatment: https://www.mobot.org/plantscience/bfna/V3/Radulaceae.htm
Also consider *R. auriculata* (found on Haida Gwaii, reported for Alaska) and possibly *R. prolifera* (on northern mainland, continental climate area)
Key characters for each species (extracted from the BFNA treatment):
1. Leaves producing gemmae -> Radula complanata
2. Plants with a very strong tendency to produce primary branches associated with each leaf along the main stem, thus plumose (frond-like) in habit -> Radula obtusiloba
3. Stems without differentiated cortex leaf cells without conspicous trigones (trigones absent to minute) -> Radula bolanderi
4. Stems with differentiated cortex; leaf cells with small to conspicuous trigones and mature plants usually greater than 55 mm in length; dorsal lobe base moderately auriculate -> Radula auriculata
