Genus of the Week
Week of February 15-21
This page has been created for people who want to learn more about plants, especially in the
context of their taxonomy (Latin names, etc.). This is by no means an exhaustive list of
all available Web resources for a particular genus.
If you like this page, you should also visit the Land of the Glandular Trichomes
, a microscopic look at plants in the Lamiaceae family.
This week's genus:
Number of Species: 1
Root: From the Greek trocho, meaning "round" (as in a wheel) and dendron, meaning "tree",
probably a reference to the enormous trunk diameter of the genus (around 15 feet).
There is only one species within the genus Trochodendron: T. araliodes. This
species is a small tree native to Japan and Thailand. The flowers of this tree have no sepals or
petals, instead having repeated whorls of yellowish stamens surrounding the ovary. The wood of
this species has no vessels (one type of water-transporting component in the xylem), a
characteristic of the more primitive angiosperms.
Here are some links to images and information for the genus Trochodendron:
