Impatiens balsamina A stamp issued by MALUKU SELATAN , or so I thought until I tried to find some information
I quote from Wikipedia
“Ulrich Häger wrote in the "Großes Lexikon der Philatelie" (Great Encyclopaedia of Philately) under the keyword Maluku Selatan:
“ In 1955, approx. 150 commemorative stamps with the country name MALUKU SELATAN gradually appeared, which were supposed to have come from a new independent state formed on the Moluccas. In fact, there were efforts on the Moluccas to become independent from Indonesia, but the formation of the country never took place. But that was no obstacle for a well-known New York stamp dealer; via a middleman, he placed an order for the production of series of stamps at the Staatsdruckerei, which was promptly carried out, without making sure that Maluku Selatan really existed. These stamps, which were initially bought by many collectors due to lack of knowledge, at best have only a low value as curiosities.”
So there you are a bogus stamp
I don't have a photo of this flower but it looks very much like a plant my cousin grew from seed every year and gave to my mother.
