PRIZE ESSAY. 
On the Culture of Roses in Pots. By Mr. T. Moore. ( Read 
April 20 th, at an Evening Meeting of the Regent's Park 
Gardeners' Association.) 
By modern botanists, the genus Rosa has been divided into 
10 sections, which are called Feroces, Lind.; Bracteatje ; 
ClNNAMOMETE, Lind.; PlMPINELLIFOLIA), Lind.; CeNTI f'OLIiE, 
Lind.; Villose; RuniciNOSiE, Lind.; CaninjE, Lind.; Systyl.®, 
Lind. ; and Banksi®, Lind. 
§ 1. Feroces; these are distinguished by their branches 
being clothed with a permanent tomentum, and also with nume¬ 
rous prickles and bristles, and by their perfectly smooth, naked 
fruit. The species included are of little interest, producing an 
inconsiderable number of single flowers ; they cannot, therefore, 
be recommended for pot culture. 
§ 2. Bracteat®. These plants are chiefly distinguishable 
from the preceding by the wooliness of their fruit and by their 
usually shining leaves; they have, also, the prickles situated in 
pairs beneath the stipules. Rosa microphylla, and R. bracteata 
{the Macartney rose) are included in this section. 
§ 3. Cinnamome® consists of plants of compact and erect 
habit; they may be known by their long lanceolate leaflets, 
which are without glands; and by their small, round, red fruit. 
The common Cinnamon rose is the type of those included in 
this section. 
§ 4. Pimpinellifoli® . These, though differing in habit from 
the preceding, are yet closely allied to them in artificial cha¬ 
racter; the greater number of leaflets, the flowers universally 
without bracteas, and the total absence of stipular prickles, 
are the chief points of distinction. In this section are included 
Rosa spinosissima {the Scotch rose ), and R. sulphurea {the double 
yellow rose). 
§ 5. Centifoli®. These are readily distinguishable from the 
preceding sections by their thickened disc, and divided or com¬ 
pound sepals ; and from the following, by their being setigerous, 
that is, bearing setse or bristles along the branches. In this 
section are comprehended Rosa Damascena {the Damask rose), 
with its varieties, including those known as “ perpetuals;” R.
