ZORNIA. A genus of curious, exotic, herba- 
ceous plants, of the hedysarum division of the 
leguminous order. Seven species have been in- 
troduced to Britain from the Indies, Australia, 
North America, and Southern Africa; and four 
or five more are known. Two of the introduced 
species have perennial roots and quadrifoliate 
leaves, and require the protection of the green- 
house; the other five have annual roots and bi- 
foliate leaves, and require the protection of the 
stove ; both of the former, and most of the latter 
have yellow flowers; and all love a somewhat 
light soil, and bloom in July and August.

ZUCCAGNIA. A small genus of ornamental, 
exotic, bulbous-rooted plants, of the asphodel 
tribe. The green species, Z. viridis, was intro- 
duced to Britain from the Cape of Good Hope 
about 75 years ago; and has a height of 8 or 10 
inches, and carries green flowers in August. 
ZYGOPETALUM, a genus of ornamental, tro- 
pical, epiphytous plants, of the orchis family. It 
takes its name from the petals being joined at 
the base. Several species of great beauty, with 
flowers of variegated colours, have been intro- 
duced to British gardens from Demerara and 
Brazil. See the article Orcuis.

ZYGOPHYLLUM. A diversified genus of or- 
namental, exotic, thalamiflorous plants, consti- 
tuting the type of the natural order Zygophyllez 
or Zygophylleaceze. This order is nearly allied 
to the rue family ; it belongs wholly to the tro- 
pics and to the warm parts of the temperate 
zones; and it comprises within the gardens of 
Britain 9 or 10 stove species, nearly 30 green- 
house species, and 3 or 4 hardy or half-hardy 
species belonging to the seven genera Zygo- 
phyllum, guiacum, tribulus, melianthus, fagonia, 
larrea, and porlieria. Some of the species are 
herbs, remarkable for the softness of their stems, 
and others are shrubs still more remarkable for 
the excessive hardness of their wood. <A feware 
medicinal, some are curious, and many are orna- 
mental. The name Zygophyllum signifies “yoked 
| leaf,” and alludes to the circumstance of the 
leaves growing in pairs. One herbaceous spe- 
| cies of the genus zygophyllum, three low trail- 
ing species, and nine or 10 shrubby species, vary- 
ing in height from 1 foot to 7 feet, have been 
introduced to Britain from Syria, Egypt, St. Jago, 
the Canary Islands, and the Cape of Good Hope. 
Most have yellow or orange-coloured flowers ; 
and nearly all may be propagated from cuttings. 
The herbaceous zygophyllum, or bean caper, 
Z. fabago, is the species best known, and possesses 
some medicinal reputation as an anthelmintic, 
and may be selected as a sufficient specimen of 
the whole genus. It is a native of Syria; and 
was introduced to Britain toward the close of the 
16th century. Its root is thick and fleshy, and 
strikes deep into the ground, and will grow as 
thick as a man’s arm; its stems are annual, and 
are proportionate in number to the age and size 
and vigour of the root, and are smooth, green, 
and jointed, and send out a few side branches, 
and usually attain a height of 3 or 4 feet ; its 
leaves stands in pairs on footstalks of about an 
inch in length, and are smooth and fleshy like 
those of purslane, and have a bluish green col- 
our; its flowers come out in twos and threes on 
short footstalks from the wings of the stems, and 
have each five roundish concave petals of a red- 
dish or orange and white colour, and bloom from 
July till September; and its fruit are oblong, 
prismatic, five-sided capsules, and have their cells 
full of roundish seeds.
