Dear Dr. Singh ji: Even though I am very new to this group.... and not a botanist, but I have seen this on many occasions.... and just like you me too, I always thought that the flowers looked remarkably like Thumbergia alata. That's a vine.... and the leaves are different...
may I take a bold step and suggest a name... I think my diagnosis is correct based on these two pictures.... its a plant colloquially called the Sesame tree. Its a member of family Pedaliacae, to be specific its name is *Uncarina grandidieri *.... originally from Madagascar... found in many sun-rooms in homes and hothouses in NY often grown in the same sort of climate control as various cacti, so your finding it in a cactus garden in North India seems very appropriate. Thanks for reading this.
