The Commelinew, of which the present genus is a co- 
ordinate, were comprised in the Juncee of Jussieu, but have 
been since detached by Mr. Brown, and the group defined 
by the following character. Calyx three-parted. Corolla 
of three petals, with the ungues sometimes connate (united). 
Stamens six or sometimes fewer, hypogynous (inserted be- 
low the pistil), a part of them often either antherless or 
with othershaped anthers. Germen 2-3-celled, with few- 
seeded cells: style single: stigma single. Capsule 2-3-celled, 
2-3-valved, valves septiferous (partitionbearing) along their 
middle: seeds generally two, and inserted at the inner 
angle of the cell. Embryo trochleate (pullied or like a 
short cylinder constricted at the middle), sunk in a hollow 
of the solid-fleshed albumen opposite the umbilicus. All 
the genera consist of herbaceous plants with leaves that are 
generally sheathing at the base. 
Trapescantia differs from ComMMELINA in having six 
uniform anthers.
