Dear all,
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.
Best wishes, Chris Fraser-Jenkins, Cascais, Portugal.

To me also appears close to Nephrolepis exaltata, cv. 'Bostoniensis' as
identified by Chris ji in Alka ji's recent post from Goa.

Garg Ji,
Resurfacing my post of Nephrolepis Species from Sri Lanka.
This looks close to Alka Ji's recent post from Goa.
Nephrolepis biserrata var. furcans was suggested by Pankaj Ji and Tanay.
Regards,
Aarti
