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

[J.M. Garg]

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

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.

Garg Ji, Chris Ji,

Thanks a lot for validating my post.
