I thought better not to postpone, so I referred my thesis (ofcourse not Lits. as Library is closed). Before going to detail again I reiterate the WCSP and GRIN etc. are compiled work, based on lits. they upload the data. In my thesis I wrote, (only required portion I am reproducing, actually 3 page notes was written) Mentha longifolia is exceedingly polymorphic due to which innumerable number of specific or infra-specific taxa were described throughout its range. Briquet in Engler & Prantl’s Pflansenfamilien (1895 – 97) recognized 21 subspecies and 150 varieties. In India, with the available substantial amount of herbarium specimens, the choice is, either to recognize unending number of ill-defined taxa or to admit that such a recognization is hopelessly artificial and that for general purposes easily circumscribed and well-defined taxa are the only practical solution. In this case, it is felt reasonable to recognize formally only one species with the following 3 variants since they appear to be some extent holding well.
Hedge and Lamond (1968) in their account of Afgan Labiatae recognized two subspecies viz., longifolia and hymalaiensis under M. longifolia and considered the varieties royleana and incana as synonyms of the typical subspecies longifolia. ---- which is followed in GRIN Hedge (1990) in Flora of Pakistan tentatively recognized two species, viz., M. longifolia and M. royleana ---which is followed in WCSP But in my work, I recognised M. Longifolia with two vars. royleana and incana as per my view.[third var is longifolia] In other words Taxonomy is based on personal opinions and it varies from person to person. Hope this would be useful in solving the doubt. Sampath Kumar From: "V. Sampath Kumar " <vskuma...@rediffmail.com> Sent: Sun, 10 May 2015 14:52:48 To: "J.M.

Prantl, Nat. Pflanzenfam. 4(3a):322. 1897 (Syn: (=) Mentha longifolia subsp. royleana (Benth.) Briq.; (=) Mentha royleana Benth.) with distribution in India [n.w.]; Nepal; Pakistan [n.] Accordingly we have been folllowing our species from North West Himalayas as Mentha longifolia subsp. hymalaiensis as per efi thread. (Pl. also see Flora of Pak) As per WCSP, Mentha longifolia subsp. hymalaiensis (Briq.) Briq. is a syn. of Mentha royleana var. royleana with distribution from Pakistan to W. Himalaya WCSP treats Mentha incana Willd. as a syn. of Mentha longifolia subsp. longifolia. with distribution in Himalayas (? but does it show any distribution in India). Flora of China does not show any distribution of Mentha longifolia (Linnaeus) Hudson in India. Pl. clarify. On 5 May 2015 at 10:49, V.

I am providing key here for clarification. 1a. Spikes slender, interrupted throughout; calyx 1 / 1.5 mm long, teeth less than half the length of the tube M. incana b.
