Naringin is considered the main effective compound of Drynaria Rhizome, which is used commonly in the treatment of osteoporosis in traditional Chinese medicine.
Naringin has been reported as the main effective component of Drynaria Rhizome, which can induce the expression of the osteogenic markers in the osteoblast cell line and BMSC (Zhang et al.
In an analogous way, the humus-collecting fronds of larger Platycerium or Drynaria
individuals allow these canopy-dwelling ferns to obtain more nutrients, while juveniles only feature green fronds (Goebel, 1913).

Over the many years of subsequent research additional examples of ferns with foliar nectaries have been added to the list: Platycerium (Dummer, 1911); the Aglaomorpha and Drynaria
group (Luttge, 1971; Zamora and Vargas, 1974; Potes, 2010); Polybotrya and Pleopeltis (as Polypodium) (Koptur, 1982; Koptur et al.
Following the previously published molecular systematic studies of leptosporangiate ferns (Schuettpelz and Pryer, 2007), in which it is well established that eupolypods II is most closely related to eupolypods I, we selected Drynaria
rigidula, Dryopteris uniform& and Polypodium vulgate as outgroups.
Thirdly, in contrast to the above, there are some endangered pteridophytes, like Hemigramma decurrens, Drynaria
rigidula and Leptochilus cantoniensis, that exist both within and outside the nature reserves but grow well because of their wider distribution and apparently better adaptability.

The contribution of these data to cladistic analyses of Drynaria
and Aglaomorpha is discussed.
