Seeds very unripe, The sepals are, as in several species of Dyschoriste, united into 
a tube by a scarious membrane one cell thick, which disrupts at a touch when t it 
fruit is formed. Botanists who have boiled the calyx or applied a reagent find i 
d-sepalous nearly or quite to the base.

Calyx divided nearly to the base; segments 5, subequal, linear. 
Corolla (in African species) orange, withering off dull red; tube long; 
linear, hardly dilated even at the top ; lobes 5, subequal, obovate, ei. 
or less oblique, contorted in bud. Stamens 2, with 2 small oid 
Ments often added; anther-cells muticous; pollen short, en ara 
reticulated ; stopples 3, Ovary glabrous or nearly so, covered with a
