Chassalia boryana (Bois Corail).


  This genus consists of some 40 to 50 species, with most belonging to tropical regions of Africa and Madagascar. Some 9 species are found in the Mascarenes.  

  They are shrubs, more rarely small trees or grasses. Leaves are opposite, or rarely in 3.  Stipules are interpetiolar, sometimes fused in a sheath, entire or not, often associated with hairs at the lateral internal base and are persistent.  Flowers are hermaphrodites.  Heterostyles are often small in a branched inflorescence from which each unit is usually a small capitulum.  Some species have pedicilate flowers.  Bracts are small. 

  Calyx is ovoid or oblong, more or less ribbed, with a small tube and triangular or linear lobes.  The floral buds are often winged.  Corolla is white, pink or red-violet, sometimes yellow inside.  The ovary is bilocular.  The locules are uniovulated, with ovules basally placed and upright.  Styles with linear stigmatic lobes are characteristics of this genus.  Fruit is fleshy, hemispheric or plan-convex, often having a dorsal crest indicating the line of dehiscence.  Seed is concave-convex, with a pale testa.
