The two Malpighias featured are not common at all in the urban context. I have seen them rarely in Puerto Rico, country side or the dominant concrete/asphalt. You may have your own criteria to determine rarity, uniqueness. Mine is simple.
The story is short. The fruit of Malpighia glabra is tangy, nice looking fruit, almost fire engine red. Most people brag about the amount of vitamin C and many cliches they hear and repeat through their life as if it is a big deal.
Never mind about that. I think it is attractive with dropping branches and small leaves. This shrub belongs to the less than ten plants club, in the over 100 collection, bought in a nursery.
The other, Malpighia coccigera, is an exchange. I noticed it two houses down, in Blondie's front yard. I talked to Myrta, a nice lady and maid. The deal was done with a Gardenia. Besides this house in restoration almost as long as the Gaudi cathedral, to become a bed and breakfast, I have seen it just
once after that, in Ponce de Leon avenue.
