Ochna unknowna

This is so exquisite a flowering plant that I must talk about it here. I have this small plant for many years and always have the itch to know its species name but it is so far but a line on my bucket list! This clearly belongs to the genus Ochna but it is much smaller and very slow growing. The flowers are similar to that of other species of Ochna, but smaller. What particularly differentiates this species from its other relatives is that all the flowers face the ground when opened. After flowering, this Ochna produces the same black seeds that earned the familiar nickname "Micky Mouse." The seeds are quite easily germinated into small and very very slow growing plants. So... my now project is what is this species? I know this is not to be confused with Ochna species grown as bonsai at nurseries.
