Could you supply photographs of the underside of the leaves showing the sori to allow a fuller identification? It appears to be Polypodiaceae or something very similar. I tried but it did not show sori This looks like one of the hybrids of Nephrolepis exaltata Can it be Nephrolepis exaltata (sword fern, kupukupu) can this be Nephrolepis exaltata var. whitmanii Yes this is.     ferns: Is it possible to grow new ferms from the spores? I tried once but failed. Please let me know. its possible but you need to grown then in culture media and then transfer !! quite hard to grown them naturally I think this is Nephrolepis cordifolia The photo is a very fine – prize-winning – specimen of a Nephrolepis. It may well be N. exaltata, a tropical American species, widely cultivated and with many ornate and fancy cultivars as well. However I seem to have mislaid my copy of the monograph, so can’t look up the details until I find it. Maybe you can find the well known journal in a library: Hovenkamp, P.H. & Miyamoto, A conspectus of the native and naturalised species of Nephrolepis (Nephrolepidaceae) in the world, Blumea 50: 279-322. Apologies – when I wrote about it not being N. cordifolia … posting was not there. But actually this present species has a longer pinna etc. than N. cordifolia. N. cordifolia, which is a conserved name, has dark, bicolorous scales on the stipe. I think this should be Nephrolepis exaltata only. There are many variations in this taxa… In some varieties of Nephrolepis exaltata I have seen new plant emerging from the tips if they are touching the ground. …, you may try tying some moss on the tip. By the way, this grows so luxuriantly, why now just divide the bunch on the base into multiple parts. I used to do the same, but then I got fed up of this fast Yes it is a fern (Division – Pteridophyta). This might be a species of Nephrolepis. I am not sure and please consider this as a clue to go ahead. Yes this is very well Nephrolepis, the sword fern. Could be a variety of N. exaltata !! This is Nephrolepis exaltata var. whitmanii. Yes, I quite agree. I think it is the cultivar ‘Bostoniensis’ (“Boston fern”), well known in gardens around the world. It always seems to throw some perfectly normal fronds and some plumose ones simultaneously oh sorry sir, its my mistake. Yes cv is written differently.
Place : Byculla Gardens Date : February 2010 Habitat : Cultivated I think this is Nephrolepis exaltata. Yes, it hardly needs confirming but these two slightly different cultivars (yellow and greeen) are both N. exaltata, originally a native of the Americas, but now cultivated world-wide in many hundreds of gardens, especially as the many different abnormal monstrosities, which constitute various different named cultivars. The natural species has simple pinnae, but sometimes the plumose (very divided) forms and furcate forms are so different in shape that it is hard to tell which actual species they belong to. However in Nephrolepis the stipe-scales are very helpful and can pinpoint the underlying species even when the shape has become unrecognisable due to these genetic mutations. Anyway, the fern itself is not very remarkable as it is widely grown, but I must offer my congratulations to the splendid vertical stand they have been arranged in – I have never seen such a fine display in any of the horticultural shows I often visit. If that were shown at the annual Royal Horticultural Show, Chelsea, London, one of the biggest and best known shows, I’m sure it would receive a gold medal. The Queen (of England, I mean) usually goes to visit that show, and Prince Charles is now a patron of the British Pteridological Society (ferns!) and grows many hardy ferns and cultivars in his superb garden at Highgrove, Gloucestershire, so would undoubtedly be very impressed. Now I understand what “vertical gardening” means – I struggle to be a mere horizontal gardener, out the back of my flat in Kathmandu, though the climate is fairly kind to us, apart from the Winter drought, when there’s also no water in the taps, either! In the UK there are many very nicely organised fern-gardens, with greenhouses for the tropical species, but this display beats the lot! Perhaps it needs more variation in the species grown, to add to the interest, but the idea and concept are spectacular.
efloraofindia:”For Id 26092011MR5’’ ?tall fern Pune: Date sep 2011 Pune Height about 10-11 ft Fern with long foliage No sori was seen on the foliage which came out throught the fence i think a fern nepherolepsis sps It may be nephrolepis boston I think it is Nepherolepis exaltata Yes, it’s a beautiful Nephrolepis exaltata cultivar, but I think not cv. “Bostoniensis” as far as I know. One needs to see the N. American literature on them by Morton and others. Also Hovenkamp’s monograph of Nephrolepis.
Requesting ID of this fern – Jijamata Udyan, Mumbai – Jun 2014 :: 08JUL14 :: ARK-09 : 5 posts by 3 authors. Attachments (2). Requesting to please ID this fern captured in Jijamata Udyan, Mumbai in June 2014. I have seen it at many other places in gardens. The fern is Adiantum pedatum Nephrolepis exaltata cv. ‘Duffii’ – an extraordinary and popularly grown cultivar abnormality of the exotic N. exaltata.    Fern FOR ID :: TMC Biodiversity Park :: 22 APR 18 : 4 posts by 2 authors. TMC Biodiversity Park Thane Date: April 22, 2018 … Altitude: about 15 m (50 feet) asl Dear friends, please help me with genus level ID of this fern … hopefully these photos give some hint to the garden enthusiasts. Well we can go quite a lot further than generic level! It is a well known and commonly commercially cultivated cultivar of an exotic American species, Nephrolepis exaltata cv. ‘Bostoniensis’. “The Boston Fern“. It will be nice if your Park collects together as many species of ferns native to the State as can be grown at your altitude. I can help naming them, if needed – as can Botanical Institutes in Maharashtra.
Goa, May 2019 :: Ornamental fern for ID :: ARK2019-49 : 4 posts by 2 authors. Attachments (3) Saw this fern in a resort in Goa in May 2019. Is this Nephrolepis biserrata or N. falcata, matches with the images for these 2 species in efi? This is a cultivar (i.e. a cultivated abnormality) of the American Nephrolepis exaltata, cv. ‘Bostoniensis’, the famous Boston fern. N. falciformis is often cultivated in gardens in India, but is not native and it is often misidentified as N. falcata, not present in India. N. biserrata has rather different pinnae and inframarginal sori and is native. Looks like Nephrolepis exaltata ? I also think Nephrolepis exaltata Yes, it’s another abnormality, maintained as a cultivar and is most probably derived from the American species, N. exaltata, as you say. I don’t know a name for this particular cultivar, but many of them were illustrated by the late Barbara-Jo Hoshizaki in her well known book, and also in some Japanese Coffee-table books of cultivars. There are very many different ones and they are of major commercial importance in horticulture – the big nursery-companies in Holland, such as Lemkes, also sell many of them.
Fern for ID : 170111 : AK-1: Nephrolepis biserrata var. furcans indeed This looks close to … recent post from Goa. Nephrolepis biserrata var. furcans was suggested by … To me also appears close to Nephrolepis exaltata, cv. ‘Bostoniensis’ as identified by … in … recent post from Goa. That’s a very fine photo of a very splendid and quite typical plant of the very well known cultivar N. exaltata cv. ‘Bostoniensis. It is not similar to N. biserrata, as suggested (apart from that most Nephrolepis species look generally similar). The sori and their position and the shape of the pinna-bases and their texture is quite different – even though it is always difficult to relate abnormal genetic mutants to the natural wild species. I’d suggest studying the generally rather good Nephrolepis monograph by Hovenkamp & Miyamoto (2005) and looking at authentically identified N. biserrata in a good herbarium (remembering many herbaria also have many mididentifications by less experienced workers as well), in Floras etc. \ I expect the name N. biserrata var. furcans (who described that?) may well be an erroneous name and needs reidentification (from its type), but I have not looked into that. There is a Moore name, N. davalliodes var furcans, which is a synonym of N. biserrata, but it does not apply to the present plant. Here is part of my note from Indian Checklist 3 (in prep.), An annotated Checklist of Indian Pteridophytes vol. 3, that may help re some of the many known cultivars in several species – in this case under the account of the American species, N. exaltata: The natural plant is rather more handsome in its flatter fronds and close pinnae than its many abnormal cultivars, but is less often cultivated. The species seldom escapes from cultivation in the Indian region, but sometimes establishes in the wild, at least temporarily, in South India, not too far from parks or gardens. It is widely cultivated in gardens or as a house-plant throughout the world in the form of various ornate cultivars of much commercial importance, including in India. These cultivars differ markedly from the norm in degree of lobing and dissection of their pinnae, sometimes being regularly furcate or bifurcate (cv. ‘Bostoniensis’) and sometimes becoming highly dissect. Many of them often bear occasional throw-back fronds or part-fronds to the normal species, borne on the same plant as the modified fronds. Several of the cultivars constantly produce no fertile fronds. Morton (1958), Pichi Sermolli (1969), Hoshizaki & Moran (2001) and Hovenkamp & Miyamoto (2005) discussed the origin and specific identity of various cultivars and Morton suggested Nephrolepis exaltata cv. ‘Bostoniensis’ could be of hybrid origin, rather than a mutation of N. exaltata itself, but this requires molecular investigation to help cast further light on its origin. When identifying species etc. one must have knowledge of the literature and of the various species concerned and their types etc. – it should not be just a matter of a wild guess because a name sounds as if it might apply. Especially in this case, the plant concerned is so well known in cultivation world-wide, including throughout India. I hope this comment may help make it and its name better known in the region.

ornamental fern (Hooghly): Nephrolepis falcata Forma furcans OK, no ID – and could not see them all, but at least one is the well known cv. ‘Bostoniensis’, so I’d suggest consulting the works on Nephrolepis cultivars and also the monograph by Hovenkamp before using an incorrect name? Quite a lot has been published on them from Morton and Benedict onwards, and some photo books too. Yes Nephrolepis falcata. .
Nephrolepis biserrata from Shimla: -Yup commonly known as fish tail fern (Syn: Aspidium biserratum Sw.) from order Polypodiales -The plants next to it is very interestingly called, SONG OF INDIA (Dracaena reflexa). And then there is one more fern, that may be Pteris cretica! I think it may be some cultivar of Nephrolepis exaltata as per images at https://efloraofindia.com/2012/05/01/nephrolepis-exaltata/ Or can it be N.biserrata only? https://en.wikipedia.org/wiki/Nephrolepis_biserrata No indeed. Nephrolepis biserrata does NOT occur in the western Indo Himalaya. You need to refer to Fraser Jenkins, Gandhi, Kholia et al., An Annotated Checklist of Indian pteridophytes (vol. 3 for Nephrolepis), to access accurate and first hand information. The plant you show is a garden grown cultivar of the purely American species, N. exaltata. As an exotic plant it is not part of the natural flora of India, and if cultivated should not be included in a work along with native species, as it is irrelevant to the Indian Flora. But you merely said “from Simla” which makes it sound like a native, in error. It is N. exaltata cv. ‘Bostoniensis’, very well known in cultivation worldwide. . References: |
