Humiriacere they have an analogy through the tribe called Cusparieae, some of 

 which have monadelphous stamens ; with Aurantiacere they agree in their 

 dotted leaves, definite stamens, occasional production of double embryos, fleshy 

 disk, and sometimes in habit in the tribe of Cusparieae. Xanthoxyleae and Si- 

 marubacese accord with them in a multitude of points. 



Geography. One genus, Dictamnus, is found in the south of Europe. 

 The Cape of Good Hope is covered with different species of Diosma and nearly 

 allied genera ; New Holland abounds in Boronias, Phebaliums, Correas, Erioste- 

 mons, and the like ; great numbers inhabit the equinoctial regions of America. 



Properties. The Diosmas, or Bucku plants, of the Cape, are well known 

 for their powerful and usually offensive odour ; they are recommended as an- 

 tispasmodics. The American species possess, in many cases, febrifugal pro- 

 perties. There is an excellent bark of this nature, used by the Catalan Capuchin 

 friars of the missions on the river Carony in South America, called the GLuina de 

 la Guayna, or de la Angostura, or Angostura, bark: this, which has been succes- 

 sively ascribed toBrucea ferruginea and twospecies of Magnolia, isnow known to 

 be the produce of Cusparia febrifuga (Bonplandia trifoliata W.) a plant of this 

 family. Humb. Cinch. For. p. 38. £«g. ed. Evodia febrifuga, one of the Q.ui- 

 nas of Brazil, has a bark so powerfully febrifugal as to compete with that of 

 Cinchona. A bark much spoken of by the miners of Brazil, under the name 

 of Casca de larangeira da terra, and in which Cinchonine was detected by Dr. 

 Gomez, probably belongs to this tree. PL Usuelles, no. 4. One of the Q,uinas 

 of Brazil is the Ticorea febrifuga : its bark is a powerful medicine in the inter- 

 mittent fevers, ibid. 16. Hortia Braziliana possesses similar properties, but 

 in a less degree. Ibid. 17. An infusion of the leaves of Ticorea jasminiflora 

 is drank in Brazil as a remedy for the disease called by the Brazilian Portu- 

 guese Bobas, and by the French Frambresia. A. St. Hil. Hist. 141. Dictam- 

 nus abounds in volatile oil to such a degree, that the atmosphere surrounding it 

 actually becomes inflammable in hot weather. Its root was formerly employed 

 as a sudorific and vermifuge. 



A. de Jussieu divides the species of this order geographically, and, what is 

 very singular, he finds their fructification in accord with their geographical dis- 

 tribution. His sections are : 



1. European. 



One from the south of Europe. 



2. Cape. 



All from the Cape of Good Hope, and scarcely extending beyond the colony. 



3. Australasian. 



Inhabitants of New Holland, within or without the tropics, and Van Die- 

 rnen's Island. 



4. American. 



Sect. I. South America, New Zealand, the Friendly Islands, Mexico. 

 Sect. II. (Cusparieae, Dec. Fraxinellae, Nces and Martins chiefly.) South 

 America, West Indies. 



Examples. Diosma, Adenandra, Agathosma, Monniera, Ticorea.
