Alliance I. RUTALES. 
Essential Character. — Style single ; or if it is ever divided into several pieces, then 
the leaves are marked with pellucid dots. 
In general, the dotted leaves sufficiently mark the genera of this alliance ; 
but for the sake of Ochnaceae, Zygophyllaceae, &c. it is necessary to add the 
character of the style being quite single up to the point. The Floerkeal alliance, 
which agrees in this last circumstance, has its fruit divided into deep lobes, as 
in Labiatae and Boraginaceae. Moreover, the general character of Rutales is 
to have a woody stem ; Floerkeales are soft herbs, and their gynobase is never 
fleshy, by which they are known from Ochnaceae, where it is remarkably suc- 
culent and enlarged. Rutales connect the Syncarpous alliance and this by 
means of Phebalium, which has quite the appearance of a Croton in Euphor- 
biaceae. 
Order XCVIII. OCHNACE.^. 
OcHNACE^, DC. Ann. Mus. 17. 398. (1811) ; Prodr. 1. 735. (1824). 
Essential Character. — Sepals 5, persistent, imbricated in aestivation. Petals hypo- 
gynous, definite, sometimes twice as many as the sepals, deciduous, spreading, imbricated 
in aestivation. Stamens 5, opposite the sepals, or 10, or indefinite in number, arising from 
a hypogynous disk ; filaments persistent ; anthers 2-celled, innate, opening by pores. Car- 
pels equal in number to the petals, lying upon an enlarged, tumid, fieshy disk (the gynobase); 
their styles combined in one ; ovule erect. Fruit composed of as many pieces as there were 
carpels, indehiscent, somewhat drupaceous, 1 -seeded, articulated with the gynobase, which 
grows with their growth. Seeds without albumen ; embryo straight ; radicle short ; coty- 
ledons thick. — Very smooth Trees or more generally under-shrubs, sometimes downy, hav- 
ing a watery juice. Leaves alternate, simple, entire, or toothed, with 2 stipules at the base. 
Flowers usually in racemes, with an articulation in the middle of the pedicels. 
Affinities. Very near Rutacese, from which they are distinguished by 
their erect ovules, the dehiscence of their anthers, and many more characters. 
They are to Polypetalous plants what Labiatae and Boraginaceae are to 
Monopetalous. 
Geography. Found in tropical India, Africa and America. 
Properties. Walkera serrata has a bitter root and leaves, and is em- 
ployed in Malabar, in decoction in milk or water, as a tonic, stomachic, and 
anti-emetic. The bark of Ochna hexasperma is used in Brazil as a cure of the 
sores produced in cattle by the punctures of insects. It probably acts as an 
astringent. PI. Usuelles, 38.
