strong contrast to the pale giauceous hue of the rest of the foliage. 
This plant is a native of Teneriffe, where it was discovered by Mr, 
Broussonet. The species most worthy of cultivation are the follow- 
ing, although there are, perhaps, many others equally deserving, yet 
they have not been brought into common use. 
Eaijkorhia antiquorum. Triangular Spurge. This has a trian- 
gular, compressed, succulent stem, rising to the height of eight or 
ten feet, and sending out many irregular, spreading, twisting 
branches, for the most part three-cornered, but some having two, 
and others four angles ; at their extremities are a few short, round- 
ish leaves, which soon fall off — and near these come out occasionally 
a few flowers, which have five thick, whitish petals, with a large 
three-cornered germ in the centre — the flowers soon dropping off 
without producing seeds. It grows naturally in the East Indies. 
It has generally been taken for the true Euphorbium ; but Martyn 
observes that it is from the next species following that the drug now 
imported under that name is taken. 
There is a variety with a naked, three-cornered, compressed stalk, 
sending out a great number of erect branches, which are also gen- 
erally three-cornered, but sometimes four-cornered, armed with 
short, crooked spines, having no leaves. The plants have not pro- 
duced flowers here. This is also a native of India. 
EaiDhorhia Canariensis. Canary Spurge. This species, in its 
native country, grows to the height of twenty feet or more, but in 
this climate it is rarely seen more than six or seven ; the stem is 
very thick, green and succulent, having four or five large angles, 
closely armed with black looking and crooked spines, which come 
out by pairs at every indenture ; it sends out from every side large 
succulent branches of the same form, which extend to the distance 
of two or three feet, then turning their ends upwards, so that the 
plants when well grown have some resemblance to a chandelier; 
they have no leaves, but are closely armed with black spines, like 
the stem ; at the ends of the branches the flowers make their appear-
