2 varieties, both in Australia; 1 variety in Victoria. Davallia solida var. solida is known with certainty in Australia only from northeast Queensland. It is distinguished from Davallia solida var. pyxidata by having scattered scales on the udersides of the lamina, whereas the lamina in Davallia solida var. pyxidata is glabrous. Nooteboom (1994) included the Fijian endemic Davallia fejeensis within Davallia solida. Davallia fejeensis has much narrower ultimate segments which gives the frond a more lacy appearance, however, further work is required to determine whether it is distinct from D. solida. Profile for Davallia solida var. pyxidata provided under variety.
