 of whichthe Proteacea make a conspicuous part, con- 

 sisting of Protea^ Banksia^ Lambertia, Embothrium^ 

 &c. See Botany ofNexv Holland, t. 7 — 10. Scabiosa,

 remarkable for its capsula circumscissa, a membra-

 the Aggregata or Aggregate flowers belong to the fourth class. 

 Cefihalanthus or Button bush is an American example. This 

 however is included the Rubiacex.'^ 



(125) [The Riibiacex of Jussieu including the Stellate of Lin- 

 naeus have a regular corolla, four or five parted, wilii the same 

 number of stamens inserted in its tube. The fruit resembles 

 two naked seeds, or is a single capsule or berry. Leaves com- 

 monly opposite as in Houatonia, or whorled as in Guliuvi.~\^ 



(126) [^Cuscuta .itnericana, has always five stamens.]
