Anther The male part of a flower, which produces pollen. Also known as a stamen.
Berry A fleshy fruit with no stony layer surrounding the seed. Date seeds are composed almost entirely of hard endosperm, they are not covered by a hard layer.
Dioecious Individual plants are either male or female.
Drupe A fleshy fruit with a stony layer derived from the endocarp enclosing the seed (e.g. Prunus spp.). Dates are berries, not drupes, although most sources seem to classify them as drupes. In strictly botanical terms their seeds should be referred to as 'seeds'. [diagram]
Endocarp The innermost differentiated layer of the pericarp.
Raphe The united portions of the funicle and outer integument in an ovule which is bent over against the funicle.
Spathe Technically the leaf-like bract surrounding the flower, but usually taken to mean the whole male flower cut for use in the artificial pollination of dates.
