I would love to find some Fortunella hindsii seeds.
I had many rooted cuttings, etc in my trade list for trade.
i have just today managed to get 12 fortunella hindsii dwarf orange tree seeds off of amazon if that would help you . it would make an amazing indoor bonsai for my collection . i am just soaking 6 of them in water over night before planting tommorow . i live in england uk & i was very happy to find them on amazon as there fruit is tiny in perfect proportion
