Order XLVII. FRANKENIACE^. 
FRANKENiACiE, Aug, de St. Hilaire Mem. Plac. Centr. 39. (181.5); DC. Prodr. 1. 349. 
(1824); Lind/. Synods. 38. (1829). 
Essential Character. — Sepals 4-5, united in a furrowed tube, persistent, equal. 
Petal alternate with the sepals, hypogynous, unguiculate, with appendages at the base of 
the limb. Stamens hypogynous, either equal in number to the petals, and alternate with 
them, or having a tendency to double the number ; anthers roundish, versatile. Ovary 
superior; style filiform, 2-fid or 3-fid. Capsule 1-celled, enclosed in the calyx, 2- 3- or 
4-valved, many-seeded. Seeds attached to the margins of the valves, very minute ; embryo 
straight, erect, in the midst of albumen (divided into two plates, Gcertn.fil.) — Herbaceous 
plants or under-shrubs. Stems very much branched. Leaves opposite, exstipulate, with a 
membranous sheathing base ; often revolute at the edge. Flowers sessile in the divisions 
of the branches, and terminal, embosomed in leaves, usually pink. 
Anomalies. Wormskioldia has a siliquose fruit, alternate deeply lobed leaves, and a 
different habit. 
Affinities. Allied on the one hand to Silenacese, from which they are 
distinguished by their different placentation, and by the form of their embryo ; 
to Linacese, from which they are known by their unilocular fruit ; and on the 
other to Violaceae, which differ in having a loculicidal, not septicidal, dehi- 
scence. Their habit is that of Amarantacese and lUecebraceae, from which 
their petals and compound fruit divide them. Wormskioldia is a very ano- 
malous plant. It seems more nearly allied to this than any other order, and 
certainly does not belong to Droseracese, in which it is placed by Achille 
Richard provisionally. 
Geography. TTiis order is chiefly found in the north of Africa and south 
of Europe. Two species are natives of the Cape of Good Hope, 1 of South 
America, 4 of New Holland, and 3 of temperate Asia. None have been found 
in tropical India or North America.

Alliance III. PASSIONALES, 
Essential Character. — Flowers with a ring or crown of sterile stamens. Petioles 
generally glandular. Embryo never curved so that the radicle lies on the cotyledons. 
The foregoing characters collect a set of orders, the mutual relationship of 
which is of the strongest kind. But in the order Tumeracese, the crown of 
sterile stamens is wanting, and so far the character of the alliance is weakened. 
Nevertheless it seems unadvisable to separate Turneracese far from Malesher- 
biaceae. 
Order XLVIII. PASSIFLORACE^, 
The Passion-Flower Tribe. 
Passiflore^, Juss. Ann. Mus. 6. 102. (1805) ; Id. Diet, des Sciences Nat. 38. 48. (1825) ; 
DC. Prodr. 3. 321. (1828) ; Achille Richard Diet. Class. 13. 95. (1828). 
Essential Character. — Sepals 5, sometimes irregular, combined in a tube of variable 
length, the sides and throat of which are lined by filamentous or annular processes, appa-
