Description : This is another species close to L. chienii differing in: pinnules of pinnate pinnae as well as upper simple pinnae narrowly cuneate, forming angles 30°–45°, lower edge never dimidiate, straight, or very slightly roundly curved outwards; the margin of lobes less interrupted and sori more continuous, with up to three breaks in each pinnule; lateral pinnae of lower pinnate pinnae becoming smaller towards distal portion and apical pinnules being not so distinct, upper simple pinnae not much larger than lateral pinnules of lower pinnate pinnae.


Thailand : PENINSULAR: Surat Thani (Ko Pha-ngan), Krabi (Khao Phanom Bencha), Nakhon Si Thammarat (Khao Luang), Yala (Gunong Ina).


Distribution : Indochina (type), Hainan, Malesia.


Ecology : Terrestrial or on rocks in evergreen forests at low to medium altitudes (500–1,100 m).


Notes: In definition we may distinguish this from the preceding species and from the variety of the following one, but there are various intermediate forms hardly referable to any of them. In some specimens determined to this species, we cannot overlook the presence of dimidiate pinnules, especially in simple upper pinnae. The distal pinnules of the lower pinnate pinnae are much smaller in some specimens identified as Lindsaea chienii and have the larger apical pinnules in a frond on the same stock.
