52 NOTES ON NEW OR RARE PLANTS, 
flowers are drooping, and from eight to ten inches long. A single 
flower is about two inches across. ‘The sepals and petals are white, 
tinged with rose. The lip is very large, three lobed, the middle one 
fringed at the edge. At the base it is white, with the rest of a deep 
rosy-purple. It merits a place in every collection (Figured in the 
Bot. Mag. 4427). Its natural habit is to grow on trees, blocks of 
wood are usually used in this country set upright, three or four feet 
long; to the top of which the roots are secured ; and as they descend, 
the long block allows space. The /®rides, Mr. Smith observes, do 
well when the roots can affix themselves to the walls of the stove, 
especially if moist. Chimney-pipes answer well, moistening the 
surface. The /Erides require a very warm part of the Orchid-house. 
BROWALLIA SPECIOSA. 
A fine shrubby new species introduced by Messrs. Veitchs’. The 
flowers are about an inch and a-half across, of a blueish lilac, with a 
pale yellow eye. It is a valuable plant for the greenhouse or con- 
servatory. 
DIPLADENIA NOBILIS—NOBLE DIPLADENIA. 
This handsome species is a native of Brazil. It is a stove-climber, 
and delights to be placed in full exposure to the sun, or the flowers will 
not fully open, nor be in equal profusion. It delights in a compost of 
equal parts of loam, peat, and sand. In the growing season, it requires 
a moist atmosphere and a free supply of water at the roots. Weakish 
liquid manure occasionally given is very beneficial. In the winter, 
keep it dry, a season of rest being required, The flowers are borne in 
terminal one-sided racemes, of six or eight together. The corolla is 
tube bell-shaped, two inches long, the expanded surface border, about 
thesame across. There are two varieties of it, one a pretty pink colour, 
with a‘darker inside tube; the other white, with a dark rosy inside tube : 
both are handsome, and merit a place in the stove. (Figured in 
Pax. Mag. Bot.) It is now in several of the London nurseries. 
Exacum Zryuanica—-Creyton Exacvum. (Syn. Chironia trinervis. 
Lisianthus Zeylanicus. ) 
A beautiful annual, which has recently been raised from seed in the 
Dublin Botanic Garden, and where it bloomed in September last. The 
stem grows erect, terminating in a corymbously branching, blooming 
head of flowers. A single flower is about an inch and a half across, of 
a rich purple-blue. It is a valuable acquisition, and merits a place in 
the stove, or warm greenhouse, probably in summer. Seeds should be 
sown early in spring, and be potted off singly as soon as ready. The 
pots should be placed in saucers, and occasional supplies of water be 
given in them. ‘The soil should be of an open turfy character, and a 
liberal drainage be given, to allow the surface water to pass away 
freely. 
LIsIANTHUS PULCHER— BEAUTIFUL LISIANTHUS. 
Mr. Purdie discovered this very beautiful species in New Grenada. 
It has bloomed in the stove at the Royal Gardens of Kew, and with
