While some species of Radula can produce similar structures, the consistent presence and positioning of these shoots in Dactyloradula helps distinguish it from related genera. [ 3 ] These features, when considered together, provide a reliable way to identify Dactyloradula and support its recognition as a distinct genus.
The most common compounds found in Radula species are 3,5-dihydroxy-2-(3-methyl-2-butenyl)bibenzyl and 2-geranyl-3,5-dihydroxybibenzyl, which often form the basic structure for more complex molecules in these plants. [17] Of particular interest is the presence of compounds similar to those found in cannabis (cannabinoids) in some Radula species
The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus .
Radula demissa forms interwoven mats of shoots that are 1.0–2.0 mm wide and up to 40 mm long. The shoots are regularly pinnately branched in male plants and sterile female plants, but become pseudodichotomous in fertile female plants due to the production of paired innovations below the female reproductive structures.

Cladoradula perrottetii is a species of liverwort is the family Radulaceae. [2] It is distributed across tropical and subtropical Southeast Asia, occurring in Thailand, Sumatra, Taiwan and Japan. It contains the small molecule perrottetinene, a cannabinoid, [3] [4] and other secondary metabolites of scientific interest including marchantin A. [5]
Radula jonesii is a species of liverwort in the family Radulaceae, [2] first described in 1988 from specimens collected in the Anaga Mountains of Tenerife. Endemic to Macaronesia, this dark to olive-green liverwort is known from five locations on Madeira Island and one location on Tenerife, where it grows as both an epiphyte on trees such as Laurus novocanariensis and as a lithophyte on shaded ...
Radula visianica is a small, green to yellowish-green plant that grows in patches. Individual shoots are typically 0.3–1.5 mm (0.012–0.059 in) wide and can reach up to 20 mm (0.79 in) in length.
