These are 2 interesting trees.
The first is the Bunchosia armeniaca (common name: Marmelo; Family: Malpighiaceae) from Tropical America. The yellow flowers are typical of this family and the orange fruits are so strikingly pretty.
The second is a Phyllanthus although I am not sure whether it is the P. acidus or other species. The new leaf flushes, leaf arrangement and the shadow of its leaves are what I like about this tree.
