ferent species, I found a like phenomenon. It Tvonld 
therefore appear that plants of this genus have an orga- 
nization which predisposes them to spontaneous produc- 
tion hy the leaves. "We have here a fresh proof that 
horticultural operations have often preceded the physio- 
logical theories concerning plants. We know, indeed, 
that oranges and other plants have long been produced 
simply hy stiiking leaves ; and. In all operations of this 
kind, the presence or absence of the neiTes or fibre has 
been studied. The necessity is still confirmed by the 
above facts. It also explains the fact of the sap's as- 
cending by the veins, and that without this sap, no 
development of the shoot could take place. — M. de St. 
Silaire, and Prof. Morren, in Ghent Annales. 
HORTICULTURAL SOCIETY. 
Fee. 19_ — The meeting was supplied with a variety 
of interesting subjects. The most remarkable was a 
plant of Dendrobium speciosum, shown by Mr. Duncan, 
gai-dener to the Eev. C. F. Chawner of Bletchinley, and 
to which, on accoimt of its excellence, a large sUver 
medal was awarded. This plant formed a dense mass, 
more than a yard in diameter, and bore upwards of 
three dozen of its splendid drooping racemes of whitish 
flowers. It had been grown in an intermediate house ; 
and was kept nearly dry, in a cold frame, all the sran- 
mer — its season of rest. Mr. Dobson, gardener to Mr. 
Beck, of Isleworth, sent a collection of very neatly 
grown orchids, to which a Knightiau medal was 
awarded : the collection contained a plant of the pretty 
CoelogjTie cristata, and specimens of Oncidium imguicu- 
latum. Messrs. Yeitch, of Exeter, exhibited the Den- 
drobium heterocarpum, imported from Moulmein ; it 
was said to be only a pale variety of D. aureum ; the 
flowers are cream-coloured, with a tawny, pencilled lip, 
and are most deUciously scented. Messrs. Henderson, 
of St. John's Wood, sent Pimelea Verschaffeltiana, a 
promising-looking species, with narrowly elliptic glau- 
cous leaves and white flowers ; and some other plants. 
The new Califomian Ceanothus dentatus was sent by 
Mr. Ingram from the Eoyal Garden at Frogmore ; the 
flowers are bright blue, forming little stalked balls, and 
promise to render it an ornamental species ; the habit of 
this and some aUied Mnds, is remarkably neat. Mr. 
Turner, of Slough, sent the Primula altaioa, a gay 
spring flower, resembling a large common primrose, 
mth pale rosy-purple flowers. A variety of interesting 
plants were sent from the garden of the Society. 
Of florists' flowers a group of six very nice Cine- 
rarias, for which a certificate was awarded, was sent by 
Ml-. Dobson, gardener to Mr. Beck, of Isleworth. They 
consisted of Cerito, the finest yet raised for form and 
compact habit; Nymph, a very pretty white; Adele 
ViUiers, tipped with rosy purple ; Maid of Artois, a 
blue, starry flower, of no merit ; Gem, badly bloomed ; 
and Bessy, a bronze prurple flower, rather remarkable. 
Cinerarias, Beauty of St. John's Wood, one of the best, 
and Cerito, were also sent fi-om the garden of the So- 
ciety. An Indian Azalea, called Howardii, was sent 
by Mr. Frost, of Dropmore; but it is too much Hie 
Triumphans to bo of much importance. 
Of fruit the supply was rather limited ; but a re- 
markably fine bunch, weighing 41b. 13oz., of the Black 
Barbarossa Grape, splendidly preserved, but badly co- 
loured, was sent by Mr. John Bevington, gardener to 
M. Phillips, Esq., Stratford-on-Avon, and received a 
Banksian medal. This Grape is of very tolerable 
quality, being very sugary; and keeping better than 
Wesf s St. Peters, is desirable on that account. Mr. 
Dunsford, market gardener, of Chingford Green, Essex, 
sent some small bunches of well-coloured Black Ham- 
burgh Grapes, from A'ines in pots ; and, from an un- 
known contributor, " J. B.," were two bunches of 
Black Grape resembling Wilmot's Hamburgh, badly 
coloured, which, it ;^was stated, had been ripe since 
June last. From Her Majesty's^ garden at Frogmore, 
Mr. Ingram sent a bundle of one hundred Asparagus, 
weighing 131bs., remai-kable for its lai-ge size and 
superior quality. This Asparagus was grown upon per- 
manent beds, heated by hot- water pipes, from which 
grass of the same quality has been produced for some 
year's past. Mr. Kestell, of Dropmore, sent two sets of 
glazed zinc and cast-fron labels for hoiticultural pm'- 
poses. The name is printed upon the back part of the 
glass, and this is placed in a sunk panel on the face of the 
tally, resting upon an elastic substance, painted of any 
desirable colour, and pressed so close as to expel and 
exclude the air, thereby preventing corrosion, the prin- 
cipal faiilt of the glazed labels at present in use.
