Cladoradula was originally established as a subgenus of Radula by the English bryologist Richard Spruce in 1885, [3] with Radula gottscheana assigned as the type species. Originally Hepstead Castle (1936) expanded the subgenus to include all species with perianths on short branches, [4] making it nearly worldwide in distribution.
For nearly 200 years, Radula remained the only genus in the family, making Radulaceae a monogeneric family within the order Porellales. [7] Herbert Castle's 1936 worldwide monograph of Radula took a broader view of Cladoradula, expanding it to include all species with reproductive structures on short branches, regardless of other features.

Within its natural habitat, Dactyloradula is a neutrophilic meso-hygrophyte found at elevations of (160–300 m a.s.l.) in a Krummholz belt, characterised by dense thickets of Juniperus sargentii thickets and tall herbaceous plants shaped by strong winds.

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
Cladoradula perrottetii grows as an epiphyte (a plant that grows on other plants) in moist, shaded environments. It has been found in several Asian countries including: India (Eastern Himalayas, Western Ghats, Central India, and the Andaman and Nicobar Islands), China, Indonesia, Japan, Nepal, Taiwan, and Thailand.

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 .
