Poaya da praia, and Poaya branca, the Ionidium Itubu of Kunth, is commonly 

 sold as true Ipecacuanha, to which it approaches very nearly in its properties. 

 At Pernambuco it is esteemed the very best, remedy that can be employed in 

 dysentery ; and the inhabitants of Rio-Grande-do-Norte consider it a specific 

 against gout. Ibid. no. 11. The foliage of the Conohoria Lobolobo is used in 

 Brazil for the same purposes as Spinach with us. Boiled, it becomes mucila- 

 ginous. Ibid. 10. Viola canina is reputed a powerful agent for the removal 

 of cutaneous affections ; and Anchietea salutaris is accounted by the Brazilians 

 not only a purgative, but also a remedy against similar maladies. M. A. St. 

 Hilaire remarks, that this notion deserves attention, as connected with the depu- 

 rative properties ascribed in Europe to Viola canina, to which, although Anchi- 

 etea is botanically related, there is nothing in its appearance which would have 

 led the Portuguese settlers to attribute the virtues of the one to the other 

 Ibid. no. 19. Sauvagesia erecta is very mucilaginous, on which account it has 

 been used in Brazil for complaints of the eyes, in Peru in disorders of the 

 bowels, and in the Antilles as diuretic, or rather in cases of slight inflammation 

 of the bladder. 



The sections adopted by Decandolle are these : 



1. Violet. 

 Petals unequal. Sepals 3 outer and broader, 2 interior. Fruit with a loculi- 

 cidal dehiscence. Stamens alternate with the petals ; filaments dilated, ex- 

 tended beyond the anthers, distinct (approximated or contracted), or occasion- 

 ally connate ; cells of the anthers finally 2-valved. 

 Examples. Calyptrion, Viola, Glossarrhen. 



2. Alsodine^. R. Brown Congo, p. 21. (1818.) 

 Petals unequal. Stamens usually either connected at the base, or adhering 

 to the inside of an elevated cup, situated between the petals and stamens. 

 Examples. Conohoria, Rinorea, Ceranthera. 



3. Sauvage^:. 



Dehiscence of the capsule septicidal. Stamens 5, fertile, opposite the pe- 

 tals, distinct ; filaments neither dilated nor extended beyond the anthers. 

 Scales 5, petaloid, alternate with the stamens. Intermediate between Viola- 

 ceae and Frankeniaceae. 



Examples. Sauvagesia, Lavradia. 



CXXXI. PASSIFLORE^:. The Passion-Flower Tribe. 



Passifloreje, Juss. Ann. Mus. 6. 102. (1805) ; Id. Diet, des Sciences Nat. 38. 48. (1825) ; Dec. 

 Prodr. 3. 321. (1828) ; Ackille Richard Diet. Class. 13. 95. (1828.) 



Diagnosis. Polypetalous dicotyledons, with definite perigynous stamens, 

 filamentous or membranous processes upon the tube of the calyx, concrete car- 

 pella, a superior 1 -celled ovarium with parietal placenta?, corolla with an imbri- 

 cated aestivation, glandular leaves, arillate seeds, and embryo in the midst of 

 fleshy albumen. 



Anomalies. Some apetalous. 



Essential Character. — Sepals 5, sometimes irregular, combined in a tube of variable 

 length, the sides and throat of which arc lined by filamentous or annular processes, apparently 

 metamorphosed petals. Petals 5. arising from tnethroatof the calvx, on the outside of the fila
