116 FLORICULTURAL NOTICES. 
yet maintains a symmetrical form, and the leaves are large, ovately-cordate, and 
liberally studded with prickles round tlie margins. In tlie hue of its blossoms, it 
resembles C. omta. 
DiLLWYNNiA sPECi5sA. — As an ornament to the greenhouse during the early 
spring months, this beautiful plant will doubtless be considered valuable. The 
abundance and density of its terminal clusters of yellow and brown flowers, con- 
trasted with its graceful character and slender foliage, render it a most attractive 
object. It has been received by Messrs. Rollison and Low, from Baron Slugel of 
Vienna ; and, in the establishments of these gentlemen, is now blooming profusely. 
It is eminently worthy of extensive cultivation. 
GoMPHOL^BiUM POLYMORPHUM. — Two charming varieties of this splendid 
plant, together with the original species, are expanding their flowers in the nursery 
of Messrs. Henderson, Pine Apple Place. They difl'er chiefly in the colour of 
their blossoms ; those of the new varieties being of a much lighter hue, and one 
of them approaching to yellow. Though this circumstance obviously renders 
them less showy, they are otherwise quite as interesting as their parent, and con- 
stitute a very pleasing diversity. 
Pj<i6nia papaveracea rt)bra. — This superb plant is flowering simultaneously 
in the nurseries of Messrs. Low and Co. Clapton, and Messrs. Young-, Epsom. Its 
principal distinguishing character is the rich purplish-red colour of the flowers, the 
base of the petals of which is also deeply stained with a still intenser hue. In 
both instances, it is kept in a greenhouse, but is most probably half hardy. 
P^oNiA tenuif5lia plena. — An almost equally splendid variety to that just 
noticed. It has flowers of a deep sanguineous red, and quite double. In other 
respects, it is similar to P. tenuifolia. 
PECULIARITIES IN THE CULTURE OF RARE AND ORNAMENTAL PLANTS, 
Clematis ccerOlea and C. Sieboldii. It will doubtless be generally 
admitted, that the two handsome plants whose names introduce the present article, 
are unequalled in beauty by any of their allies. Altliougli, in the extensive genus 
Clematis^ many very ornamental species are to be found, the subjects of tliis notice 
have received a greater share of popular admiration than any of those previously 
discovered. 
To such of our readers as have yet had no opportunity of examining flowering 
specimens, we may refer to the iigures of these species given in the fourth volume of 
this Magazine. These will be found both accurately delineated and faitlifully 
coloured. Being then unacquainted v/ith any authentic particulars respecting tlieir 
cultivation, a few additional remarks — the result of subsequent observation and 
experience — may perhaps prove serviceable. 
Many may deem it unnecessary to advert to the management of any species of 
Clematis^ so obviously simple is tljeir cultivation, and so familiar to most practical
