Fern ID from Bangladesh SM116 : 5 posts by 4 authors. Attachments (2).

Habit: Herb
Habitat: Epiphytic
Location: Dhaka City

It looks like Asplenium nidus– the Bird’s Nest Fern.

Perhaps Asplenium antiquum

Well it seems we have another “might be this”, “might be that” situation, but actually this is a common epiphyte all over Bangladesh, including in Dhaka, Sylhet and Chittagong (and Assam), where you can see it on many larger old trees. It does not have the “Bird’s Nest Fern” shape and growth, because as shown in the photo, the rhizome is creeping and fronds arise slightly apart. The Asplenium nidus complex species in the Indian region all have a crowded shuttlecock of larger leaves, with the lamina not narrowing as much to the stipe. The present fern is the abundantly common (in the N.E.) species, Microsorum punctatum. Note the spelling of Microsorum.
A. nidus group species grow deeper in natural forests, but not in the towns, in Bangladesh they only occur in the Chittagong Hill tracts, but as the last forests have now been cut down, sold and eaten, one is no longer very likely to see this group in Bangladesh. Taxonomically they are a real problem because the two(?) common Indian species (apart from A. phyllitidis agg.) are NOT true A. nidus, which was found out by Dr. Bob Johns of Kew and New Guinea. The identity of A. nidus is unsure, and needs urgently to be dealt with by means of epitypification (an interpretive accessory type) because the type is very poor – no rhizome or spores, so nothing to go on. But none of the species in Lombok etc. correspond with the N.E. Indian “A. nidus“, which extends into China. In China it was another case not sorted out by Viane, Dong etc. in the error-packed Flora of China. It appears to have been named in China, but other areas and names also need to be elucidated first. It is not A. antiquum, the far-eastern Asian species of China and Japan.
In the Andamans, with their Malesian flora, closely related to Sumatra, there is another good species, A. musifolium, as well as “A. nidus“. I have a potential name for the common wider-fronded NE Indian species – but am still checking before deciding

i found them in Mudigere talluk. they were growing on a tree. can you please help me to identify them?

This is Microsorum punctatum. Anntated Checklist of Indian Pteridophytes vol. 3: 202-205 (2020). Is that in TN. or Kerala?

It is from Karnataka.

this is from Chikkamagalur district of Karnataka, India.

in the green house at the nursery of Jijamata Udyan.

possibly Microsorium punctatum;
