- I know of no other genera with such intramarginal formation of true gemmae.
- 1990, Anthony John Edwin Smith, The Liverworts of Britain and Ireland, page 2:
- Gemmae are frequently longer than wide or of irregular shape.
According to Degenkolbe, gemmae-bearing leaves are always different in form from normal leaves.
- 2005, R. N. Chopra, Biology of Bryophytes, page 32:

Etymology
Unknown. Possibilities include:
- Cognate with Proto-Slavic *zębnǫti and Lithuanian žémbėti, both meaning “to germinate, sprout”, perhaps from Proto-Indo-European *ǵemb- or *ǵeb- (“to bud, sprout”), though such a root would be irregular for PIE;[1][2]
- From Proto-Indo-European *ǵembʰ- (“nail, tooth”), despite the semantic gap. Compare, however, Ancient Greek ὄνυξ (ónux, “claw, nail, hoof, talon, but also onyx (gem)”);
- From Proto-Italic *gen- (“to produce”), from Proto-Indo-European *ǵenh₁-; compare gignō and genus;
- A non-Indo-European substrate source. The unusual form of the word, the lack of clear cognates and the semantic category of the word make this hypothesis likely.
Pronunciation
- (Classical) IPA(key): /ˈɡem.ma/, [ˈɡɛmːä]
