Style inserted in the top of the ovarium, articulated; stigma 
simple. Capsule dicoccous, coceze 2-valved: with a free central 
placenta. Seeds small; with an immediate placentation; testa 
simple. Embryo small, straight, in fleshy, copious albumen.— 
Shrubs or sub-shrubs. Leaves opposite, quite entire, stipulate 
or substipulate. Flowers disposed in secund, bracteate spikes. 
Down or hairs on the plants simple or stellate. This order 
differs from Gentiànece, in the style being articulated; andin the 
immediate, not parietal placentation of the seeds. The plants 
contained in this order are highly ornamental, like those of Gen- 
tiünec. The Spigélia anthélmia, and other annual species, are 
used as a vermifuge ; and the root of Spigélia Marilándica, in- 
fused in water, is anthelmintic; and the wine is febrifugal.
