In the genus Trcmandni^ which has given its name to this small 

 family, there was one species tolerably distinct from the others by 

 its exterior characters known as T. verticillata ' (fig. 98-103). Of 



Platytheca vcrticillatii.

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

 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- 

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

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