its spiny nature). ORD. Ewphorbiacee. A genus of about 
nine species of ornamental stove evergreen bs, 
natives of Brazil, the West Indies, and Florida. 'They

from drypto, to tear, on account of the leaves being 
armed with stiff spines). Овр. Caryophyllem. A very 
pretty little herbaceous perennial, admirably adapted for 
ornamenting rockwork, where it becomes suffruticose, 
and produces an immense number of flowers. Increased 
either by cuttings, placed in sandy soil, under a hand 
glass; or by seeds, sown in a light compost. When seed- 
lings are of sufficient size, they should be separated 
and planted on the top of rockwork, care being taken 
to keep them watered until fresh roots are emitted.

DEY-ROT. A name given to decayed timber, caused 
by different species of Fungi, which, under certain con- 
ditions, attack woodwork in ships, houses, &c., penetrating 
the wood in all directions, and in many instances doing 
irreparable damage before they are observed. Two of the 
principal species of ieausing Dry-rot are: Merulius 
lacrymans, attacking wood in houses and other buildings ; 
Polyporus hybridus, affecting oak-timber in ships.

odour and turpentine flavour, is ranked among the most 
delieions of Indian fruits. 'The only species of the genus
