Palm sugar sap ('toddy') from the flowers. The date palm has two species, "Phoenix dactylifera" and "P. sylvestris", and both are sources of palm sugar. "P. dactylifera" is common in the Mediterranean and Middle East. "P. sylvestris" is native to Asia, mainly Pakistan and India. Date palms are cultivated mainly for dates. Palm sugar is made from the tree's sap. The nipa palm ("Nypa fruticans") is native to the coastlines and tropical regions of the Indian and Pacific Oceans. It is the only palm tree that grows in a watery mangrove biome. Only its leaves and flowers grow above water. Palm sugar
Fruit tree pollination for apple trees, although members of the genera "Andrena", "Bombus", "Halictus", and "Osmia" pollinate apple trees in the wild. Solitary bees such as ground-nesting mining bees ("Andrena") may play a far bigger role in pollination than at one time suspected. Bumble bees are sometimes present in orchards, but not usually in enough quantity to be significant pollinators; in the home garden with only a few trees, their role may be much greater. Increasingly Orchard bees (spring mason bees) are being used in fruit tree pollination. According to British writer Christopher O'Toole in his book "The Red Mason Bee", "Osmia rufa"
