or warty; basal bracts sometimes fused and succulent (together with peduncle
) to form a "receptacle," or obsolete
; ovule (inverted
) or inclined
in Chinese species. Seed drupelike or nutlike, wholly or (in Dacrydium) partly enveloped in a sometimes colored
and succulent epimatium derived from fertile ovulate scale. Cotyledons 2.
Eighteen genera and ca.
