All Coryphoideae, except Caryoteae, and all Cocos-Type and Corypha-Type stems have a lot of phytoliths all around their fvb throughout the central cylinder. Mauritia-Type stems (most of Arecoideae, erect Calamoideae and Ceroxyloideae) have few phytoliths. They are sometimes observed on the fvb of the central zone but almost none are observed on the fvb of the zone of transition of the central cylinder. Most of these silica bodies are restricted to the cortex and to the fvb of the subcortical zone in contact with the cortex.
