Thanks for showing us photographs of this Assam lemon, on which we had discussion last week, and I could sort out its identity after a lot of net search.

Thanks once again Gurcharan ji, for the id.
 
But similar plants have been identified as Citrus medica in the following sites:
 
So how to confirm this? No picture for C. longilimon available in the net. The protologue (in Bull.Univ. Osaka Perfect....1959) in also not traceable.

I am not able to distinguish it from Citrus medica, which has fruit
which is variable in shape

Assam lemon, characterised by its long fruits (distinctinctly longer than broad) have been named as C. limon at many websites, and as C. medica in many websites. It should not look strange firstly because taxonomy of Citrus is very confusing, secondly many authors consider C. limon as var. or subsp. of C. medica, and as such those not going below species level would simply call it C. medica. Plus C. longilimon (character is in the name itself) is comparatively recently established species, not known to me. NMPMD database is generally well researched, and it is from here as well photographs of Assam lemon at various websites that C. longilimon appears to be the most logical name. Plus GRIN also recognises it as distinct species.

  C. limon is generally differentiated from C. medica by much thinner and smoother rind. Let us try to find out other differentiating features (in addition to longer fruit) of C. longilimon to arrive at final conclusion.

I agree that this is Assam lemon. But the name Citrus longilimon Tanaka, although first published in 1959 and appears in several webpages, is not yet recognized by the major taxonomic databases, including TPL, POWO, GBIF etc. Also, a recent paper (cited below) discusses the morphological diversity of C. medica in NE India and includes specimens of similar fruit shape from the same region. So, I think we can treat this plant as C. medica L. for now along with C. longilimon Tanaka as a probable synonym, until it is further resolved.

Barbhuiya AR, Khan ML, Dayanandan S. Genetic structure and diversity of natural and domesticated populations of Citrus medica L. in the Eastern Himalayan region of Northeast India. Ecology and evolution. 2016 Jun;6(12):3898-911. https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece3.2174  

Thanks!

Thanks Vijayasankar for confirming that this is Assam lemon for which name C. longilimon has been published by Tanaka. We already have a page on C. longilimon, and it should go there.
