Ceroxyloideae is a subfamily of flowering plant in the palm family found mainly in the Americas with an outlying genus in each of Australia, Madagascar and the Comoros. Recently revised, the former subfamily Phytelephantoideae was reduced to the tribal level and included, while the Hyophorbeae tribe was reassigned to Arecoideae; it now contains eight genera.

[edit] Description
From small to moderate to the tallest in the family, the trunks may be solitary or clustering and lack armament. The reduplicate leaf is regularly or irregularly pinnate, bifid, or entire with pinnate ribs; crownshafts are present in some members and absent in others. There are monoecious, dioecious, and hermaphroditic palms in the group, a protective prophyll accompanies the inflorescence, and all feature peduncular bracts. Any unisexual flowers are slightly dimorphic, solitary, or in rows; all have syncarpous, triovulate gynoecium.[1][2]
[edit] Tribes
[edit] Ceroxyleae
Four widely spread genera in South America, Australia, and Madagascar, characterized by tall, rarely slender, trunks which lack crownshafts. The flowers are early-opening, solitary, spirally or subdistichously arranged, with small bracts.
[edit] Cyclospatheae
A monotypic tribe from North and Central America with moderately sized, erect trunks, with crownshafts. The flowers are solitary, spirally-arranged, hermaphroditic, and borne in the axils of small bracts.
[edit] Phytelephanteae
Three dioecious South American palms, with moderate to large, acaulescent or erect trunks. The staminate inflorescences are spikelike while the pistillate are branched and spreading. The fruit is usually born in dense clusters, each containing five to ten seeds.
