this, a separate genus has been made under the name of Plafytheca^'^ 

 which may be studied as the type, as it has regular pentamerous 

 flowers with two verticels to the androceum. The receptacle is 

 convex ; the sepals free and valvate ; the petals alternate valvate- 

 indiiplicate. Of the ten hypogynous free stamens, five are super- 

 posed to the sepals, and five more exterior and smaller to the petals.
