Hello Dinesh Ji,
I will share my experience regarding the binomials , epithets and
associated 'subtaxa'.
The plant you have posted is indeed Ipomoea hederifolia and despite some
hesitation expressed by some other members in the past as to whether
dilute color forms exist , I will say that I am aware of dilute color forms
existing within wild populations in both the New and Old World.
The addition of the subtaxa 'lutea' and sometimes 'aurantia' , although not
official was used by some growers and merchants in an attempt to give
credence to the dilute color forms (even though not yet officially
recognized) rather than use a description like "my favorite yellow or
orange dilute form". The usage of the lower taxonomic rank terms like
vaiety and forma has to start someplace and I do not believe that it is
only 'official' taxonomist who should be allowed to institute the usage of
taxonomically correct terms.
I supported the usage of recognized taxonomic terms rather than
non-taxonomic terms because I thought it would be best in the long term
regarding organizing some wild variants.
Ipomoea lutea is a distinct and separate species from either Ipomoea
hederifolia , Ipomoea coccinea or Ipomoea cristulata.
There was some substantial confusion created when a marketing firm in
Australia ( about 10 years ago) began to market seeds that they were
calling Ipomoea luteola (which is a synonym for Ipomoea hederifolia and
used mostly in Australia) but the company actually distributed Ipomoea
coccinea causing confusion amongst the Morning Glory appreciation community
and I am glad to have the opportunity to try and clarify the matter.
There is also a dilute form of Ipomoea cristulata that occurs in New Mexico
but that has not yet been given any official recognition or marketing terms.
I hope that my experience helps to clarify the matter...
regards,
Ron
