Corolla salver-shaped, with a five-parted limb, the five stamensinserted on the receptacle opposite its lobes (Plumbago) ; or else offive almost distinct unguiculate (scarious or coriaceous) petals, withthe stamens inserted on their claws! (Statice, &c.) In the former. 949 957 case the five styles are united nearly to the top; but in the latterthey are separate !
