plant for ornament ; Siphocampylus lanceolatus, a spe- 
cies of upright habit, with lanee-shapcd leaves, and deep 
salmon-pink flowers ; and an Erica, named Bumettii, 
in the way of elegantissima. Mr. Iveson, gardener to 
the Dowager Duchess of Northumberland, sent the 
Odontoglossum hastilabium. Among nmnerous showy 
plants from the garden of the Society, were the Acacias 
— celasti-ifoUa, ixiophylla, and lineata ; a beautifully 
bloomed plant of the yolk-coloured Epidendrum auran- 
tiacum ; and a small plant of the dark purple-blue Ho- 
vea chorozemoefolia. 
Mr. Fry, of Lea, Kent, exhibited a simple apparatus 
for fumigating plant houses, on the principle of the com- 
mon flower-pot plan of fumigation, which may be re- 
commended for its usefulness rather than its novelty.
