Thank you very much VIplav Ji for this new angle - heterostyly. Very interesting and much probable solution of your two morphed population over there. But it doesn't explain my query. It doesn't explain stipule character. Neither it explains hair property of corolla, within as well as without. As I said the flowers of my species may be a little hairy, but not like what had been recorded in Cooke's Flora. Leaves are rather glabrous or pubescent, not tomentose (Ref. Cooke's flora) specially underside, in my species as far as I can make out examining my records.
In short "heterostyly" doesn't explain if *Morinda tinctoria* var. *tomentosa* and *Morinda exserta* is same species or not. I said Bangladesh document doesn't sastisfy my records, in addition to what you have pointed out about the line drawing, the corolla size is smaller in that doc., style is longer than corolla tube. Thank you very much once again. Regards surajit On Wed, Apr 22, 2015 at 4:19 PM, [email protected] <[email protected]> wrote: > > Thank you Radha ji & Surajit ji for your thoughts.
