Sir / Madam,

Today one of my colleagues collected this plant from roadside. This is a wild climber and the ripe fruits are yellow, unlike the red Trchosanthes tricuspidata.


Species : UNKNOWN
Habit & Habitat : wild climber, roadside, scabrid, leaf surfaces rough
Date : 11/7/12
Place : Hooghly

Thank you & Regards,

Surajit Koley

Sir,

Thank you for the links of two closely related varieties of Cucumis melo.

I think my species is same as the one posted by Nidhan Sir at - https://groups.google.com/forum/?fromgroups#!searchin/indiantreepix/cucurbitaceae$20week/indiantreepix/qjDROD1QMgk/QJePGG-d-qUJ and by you at - https://groups.google.com/forum/#!searchin/indiantreepix/Cucumis$20melo/indiantreepix/ihPLuP1Csco/PtyDS56I4J8J. I think the lobes of the leaf blade can vary according to age of the plant, the maturity of the shoot and the maturity of the leaves. I attach here three more images and the variation in leaf blades can be seen in the first two images.


As i searched the net i found -
  1. Cucumis pubescens Wall. ex Wight & Arn. = Cucumis trigonus Roxb. = Cucumis callosus (Roettler) Cogn. = at (Plants of Nepal) http://www.efloras.org/florataxon.aspx?flora_id=110&taxon_id=242315808
  2. Cucumis callosus (Roettler) Cogn. = Cucumis melo subsp. agrestis var. agrestis Naudin, Ann. = at (Flora of Pakistan) - http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=250077277
  3. The above site also describes, "Perennial forms have been sometimes treated as a distinct species, Cucumis trigonus Roxb. The status of these taxa needs elucidation by comparative studies in the field"
  4. Citation form Bengal for Cucumis melo var. pubescens - http://www.floraofalabama.org/Plant.aspx?id=1664
So, it is likely to be Cucumis pubescens Willd. as have been suggested by you.

Regards,

surajit
