belongs, all have their fruit formed in this way, although, 

 instead of being smooth and shining, it may be woolly or 

 differently marked. 



A dry one-seeded inferior fruit is called a Cypsella. 



Protea and Clematis have also 

 dry indehiscent fruits. The styles of 

 the ovaries remain on the ripe fruit, 

 and the enclosed seed is attached at 

 one place, the placenta. A Protea 

 flower has but one ovary, but Clematis 

 has a cluster or an etserio of fruits. 

 In these flowers the ovary is borne 

 above the perianth.

A dry superior one-seeded fruit is an achene.

 is convex and fleshy ; in the rose it is hollow, and conceals 

 the hairy ovaries. 



Tripteris, Triaspis, and Portulacaria {Spekboom) have 

 winged fruits. 



A winged fruit is a samara.
