1-ovuled divisions surrounding the style. Stigma not annular. 
Tribe wii, Boragex DC. Prodr. x, 1. Chiefly herbs with some-

to which the nutlets are attached (called the gynobase). Stigma,

commonly pendulous. Nutlets 4, or by abortion fewer, distinct er 
at base united into pairs. Seeds without albumen. 
* Nutlets attached above the middle, wholly flat and thin, hori-
