Pteris vittata, commonly known variously as the Chinese brake,[3] Chinese ladder brake,[3] or simply ladder brake,[3] is a fern species in the Pteridoideae subfamily of the Pteridaceae.[4]  

It is indigenous to Asia, tropical Africa and Australia.[3] The type specimen was collected in China by Pehr Osbeck.[1]
Although it grows readily in the wild, Pteris vittata is sometimes cultivated.[3] It is grown in gardens for its attractive appearance,[3] or used in pollution control schemes:[3] it is known to be a hyperaccumulator plant of arsenic used in phytoremediation.[9]

Kindly Id this wild herb growing in moist area at Pune
I do not know whether to call this stipe and rachis but it is white hairy
Leaves greyish green with wavy margins.
New leaf appears very hairy
No flowers and fruits seen

Looks like young plant of Pteris to me. may be Pteris vittata.


Typical Pteris vittata subsp. vittata, common by the view-point on the main highway road on the way up to Pune.

Epiphytic orchid in Manipur No. 2:
Please take a look at this one also, found about the same altitude on Khayangphung, E. Manipur at approx 1800m and flowering in late November. It was growing on a fallen log.


This looks like Eria vittata to me.


Its Eria vittata……

Fern seen deep inside the moist forest on 20/5/14.
Kindly id.


the fern may be Pteris vitata


There are two simply pinnate species in the photo – the one with the narrow pinnae is Pteris vittata subsp. emodi, which occurs from lower altitude up to mid altitude and occurs throughout the Himalayan region, and in China, but not in C. and S. India (where only subsp. vittata occurs – both are common in the Indo-Himalayan region).
The one with the broad pinnae is Thelypteris (sect. Cyclosorus, subsect. Pronephrium) nudata – another lower-mid altitude species.

Pteris vittata ABJUL01/01 : 2 posts by 1 author. 5 images.
I photographed this fern first on May 15 when it was still uncurling and looked very appealing with its geometrical forms. I waited for the sori to develop and photographed it again yesterday. Unfortunately, it was on a slope by the road verge and I couldn’t reach the base to show the stipe and smaller pair of pinnae ascending from below. But the accompanying pictures strongly pointed it to be Pteris vittata. Please correct me if I am wrong. With this I have recorded four species of Pteris here including P. aspericaulis, P. cretica and P. terminalis.

15 May photo of uncurling;
Pinna at the apex suggesting Pteris species;
Thin, closely placed pinnae in pairs;
And the sori;

Superb !  Yes, P. vittata subsp. emodi

Pteris vittata


may be Pteris vittata


It’s Pteris vittata


.



Requesting a fern id: 2 high res. images.
Date: 2/10/2021
Place: IISER campus adjoining Agasthyamalai biosphere reserve, Thiruvananthapuram.
Habit: Herb
Habitat: a fern seen growing extensively in the damp rock crevices and embankments of streams.
Striking features: the leaf is leathery and the abaxial surface has a brown lining of sori.


Pteris vittata subsp. vittata.- it grows happily on rocky places and walls  as well as on the ground and is in N, S, E and west of India.



Pteris vittata ?? If so, which subspecies?: 4 images.
Date/Time-15 Jan 2022
Location-Nipani, north Karnataka
Habitat- sugarcane field.
Plant Habit-  Herb
Height-25cm


Pteris vittata (the subsp. vittata that occurs in the Indian peninsula). It can be fertile when very small, or when the plants get huge in better conditions. It tends to like old walls and rocky places.

Pteris vittata -another subspecies ?: 3 images.
Date/Time-15 Jan 2022
Location- South-western Maharashtra. Western ghat hills.
Habitat-  Wild-
Plant Habit-  Herb. in colonies.
Height–60cm.
This variety has thicker, leathery, tough leaves as compared to P. vittata subsp vittata.


Also this plant was growing in colonies in open, sunny rocky region outside the forest (as compared to P vittata subsp vittata which I found growing in crevices on limestone walls of houses in Satara city (Maharashtra) and in sugarcane field near Nipani (in plains of north-west Karnataka) )


I don’t think so. This narrower-pinna’d plant of subsp. vittata (when large – not like the little one you posted before) appears quite commonly in both north and south India, but with intermediates also occurring commonly. Nevertheless it still has quite typical (perhaps even more extreme) subsp. vittata characters, the abrupt and long drooping apical segment, pinnae rather apart and drooping, frond arching.
I have mentioned this narrow-pinna’d variation in my new forthxoming paper on P. vittata in the next Indian Fern J. and my conclusion is that it is not discretely separated from vittata s.s. and I couldn’t make sense of it as any kind of separate taxon – it seems to be what vittata s.s. can do and such plants occur widely in Asia, usually growing among plants with slightly wider pinnae.
But I point out in the paper that it has not been specifically cytologically checked – which is much needed from Upper Kothayar Lake, T.N., where … thought she got a diploid (but the squash was completely overlying and uncountable in reality) and collected both wider-pinna’s vittata s.s. and narrower like this (but not as good a specimen).
It would merit cytological investigation, though just to eliminate anything else.
To me its just P. vittata sensu stricto (syn. subsp. vittata).


Subsp. vittata often establishes colonies on old walls, but is common in natural situations on the ground as well. The narrow pinnae can also occur frequently in wall populations – there is no ecological distinction and no morphological line between the wider and narrower pinna’d plants, either.
This becomes clear on seeing more populations – but of course in peninsular India populations of P. vittata are rather few and far between – when you see more, the intemediate forms mount up!
