What plant containing single-seeded, blue-black drupes is part of the Manilkara zapota family?
Manilkara zapota Manilkara zapota, commonly known as the sapodilla ( ), is a long-lived, evergreen tree native to southern Mexico, Central America and the Caribbean. An example natural occurrence is in coastal Yucatán in the Petenes mangroves ecoregion, where it is a subdominant plant species. It was introduced to the Philippines during Spanish colonization. It is grown in large quantities in Pakistan, India, Thailand, Malaysia, Cambodia, Indonesia, Bangladesh and Mexico.
Pittosporum tenuifolium Pittosporum tenuifolium is a small evergreen tree, up to 10 m , native to New Zealand, commonly known as kōhūhū and black matipo, and by other Māori names "kohukohu" and "tawhiwhi". It is sometimes grown under the cultivar name 'Nigricans', so called because of its black stems. In horticulture it is valued for its coloured foliage (cultivated variations include purple, "silver" and variegated leaves), and for its tolerance of some horticulturally difficult growing conditions, including dry soils and shade (although in northwest Europe, cold and exposed situations do not suit it). The flowers generally go unnoticed because of their colour, a very dark reddish-purple, and are scented only at night. It is found growing wild in coastal and lower mountain forest areas up to an altitude of 900m.
