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 DecandoUe are these : — 



1. Viole;e. 



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

 a loculicidal dehiscence. Stamens alternate with the petals ; filaments 

 dilated, extended beyond the anthers, distinct (approximated or contracted), 

 or occasionally connate; cells of the anthers finally 2-valved. 



Examples. Calyptrion, Viola, Glossarrhen. 



2. AlsodinetE. R. Brown Congo, p. 21. (1818.) 

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

 hering 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 

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

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

 ceae and Frankeniacese. 



Examples. Sauvagesia, Lavradia.

Passiflore^, Jvss. Ann. Mus. 6. 102. (1805); Id. Diet, des Sciences Nat. 38. 48. (1825); 

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



Diagnosis. Polypetalous dicotyledons, with definite perigynous sta- 

 mens, filamentous or membranous processes upon the tube of the calyx, 

 concrete carpella, a superior 1-celled ovarium with parietal placentae, corolla 

 with an imbricated aestivation, glandular leaves, arillate seeds, and embryo 

 in the midst of fleshy albumen. 



Anomalies. Some apetalous. 



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

 variable length, tlie sides and throat of which are lined i)y filamentous or annular pro- 

 cesses, apparently nietam()ri)hosed petals. Petals 5, arising from the throat of the calyx, 

 on the outside of the filamentous processes, occasionally wanting, sometimes irregular, im- 

 bricated in 8estivati(tn. Stamens 5, monadelphous, rarely indefinite, surrounding the stalk of 

 the ovarium ; anthers turned outwards, linear, 2-celled, bursting longitudinally. Ovarium 

 seated on a long stalk, superior, 1-celled; sti/les 3, arising from the same point, clavate; 

 stigmas dilated. Fruit surrounded by the calyx, stalked, 1 -celled, with 3 parietal polysper- 

 mous placenta*, sometimes .'{-valved. Seeds attached in several rows to the placenta, with 

 a brittle sculptured testa surrounded by a pulpy arillus ; emhrt/n straight, in the midst of 



fleshy thin albumen; radicle turned towards the hilnm ; cotyledons Hat, leafy Herba. 



ceoits plants or sliriibs, usually clindiing, very seldom arborescent. Leaves alternate, with 

 foliaceous stipulw, often glandular. Floivers axillary or terminal, often with a 3-leaved 

 involucre. 



Affinities. The real nature of the floral envelopes of this remarkable 

 order is a question upon which botanists entertain very difi'erent opinions, 

 and their ideas of its affinities are consequently much at variance. Accord- 

 ing to Jussicu {Diet, dcs Scioices, 38. 49.), the " parts taken for petals are 

 nothing but inner divisions of the calyx, usually in a coloured state, and
