I think most of the Annona species are found in South and Central Americas.
In India,only 3 Annona species Annona muricata(Laxmanphal),Annona squamosa(Sitaphal) and Annona reticulata(Ramphal) are naturally found growing.
Regarding India Post,it has largest number of post offices in the world.
By Registered Air Mail, from India,it reaches to USA in about 15 days; for Brazil it takes about 30 days and Luc reported that to reach Mexico it took 44 days.
Usually on 3rd day from date of dispatch,post from India reaches a central place of the country(New York for USA) by Air.
From there it takes time to deliver to the recipient.
Everyone is writing about receiving seeds from Carlos,so I just expressed my feeling on the board.
I am sorry for causing inconvenience.
