Adiantum sp.

I think this is Adiantum cuneatum

That’s A. concinnum – an adventive species in India, common in its native Mexico, where it was interesting to see it in its natural environment when I went there.  It was unfortunately redescribed as if a new Indian species, Adiantum ramyam, in South India.
It shows the typical first acroscopic segments overlapping the rachis.
The specimen is a bit attenuated with segments rather far apart as it is in a shady place – it likes more sun, I think.
“A. cuneatum” is an illegitimate later homonym for another adventive species in India, A. raddeanum.

nice. never seen the leaflets go that bright red ever. nice to know. climate ?? or local soil?

Thanks … Possibly the young fronds are of that colour before turning green. Not sure.

Though would need some more clear pics of the species but from this it closely resembles Adiamtum capillus-veneris L. which has these typical paralellogram shaped leaves. It is an ornamental fern and cultivated in many botanical gardens as well.
It is known to occur in moist evergreen to semi-evergreen forests of Karnataka and down South. Hope this information helps.

Probably A. concinnum, a common adventive from Mexico – spread all over South India and also Darjeeling.  But you have to photograph the whole frond, showing the basal pinnae, and from above – not looking horizontally at it!  Please send to me, and I’ll answer when I next get onto the e-mail – I’m on tour in Shillong at present.
