Culi. O’xalis is a curious and beautiful genus. The hardy 
kinds require no care. If the roots are planted in a shady bor- 
der, they will thrive and multiply. If the seeds of annual species 
are sown in the open border in spring, the plants will rise 
freely, and if they are permitted to scatter their seeds, there will 
be a plentiful supply of plants. The greenhouse kinds are mostly 
bulbs from the Cape of Good Hope; a mixture of sand, loam, 
and peat is best suited for these; they require no water after 
they have done flowering, until they begin to grow afresh, 
these are increased by offsets from the bulbs, and by seeds. 
The most of them may be grown in a frame, but care should be 
taken that they are protected from the frost during winter. The 
stove species should be grown in the same kind of soil recom- 
mended for the greenhouse kinds; the shrubby kinds of these 
may be increased by cuttings or seeds; the herbaceous fibrous- 
rooted ones by dividing the plants at the roots or by seeds; the 
bulbous-rooted ones by offsets from the roots. But some of the 
frame and greenhouse species are fibrous-rooted, therefore they 
should also be increased by dividing the plants at the root.

but sometimes 1-seeded, never cocculiferous nor arilliferous. 
Seeds albuminous, or exalbuminous. Embryo straight, with 
a superior radicle and leafy cotyledons.—Herbs, shrubs, and 
trees variable in habit. Leaves furnished with stipulas at the 
base, usually compound, in the Zygophyllee vere opposite, but 
alternate in Zygophyllee spurie@.—This order is intermediate 
between Oxalidee and Rutacee. It is distinguished from the 
former in the styles being joined into one, never free, and in the 
seeds being without aril, as well as in the leaves being opposite, 
and furnished with stipulas ; and from the latter it differs in the 
structure of the carpels, but especially in the absence of elastic 
cocculum, which is truly notable in Rutdcee vere. At first 
sight it is distinguished from both in the twin stipulas at the 
base of the petioles. Many of the species of this order bear 
beautiful flowers, and enliven many an arid waste within the 
tropics, particularly the Tribulus cistoides. The Zygophyllum 
Fabàgo is employed as an anthelmintic, but it is in Guatacum 
that the great medical virtues of the order are to be found; 
it has been found to contain a particular substance, which is 
called Guaiacine, differing both from resin and gum.
