taken off about the month of May, and placed beneath a hand-glass at the foot of 
a south wall, where, with a slight shading, and only a moderate quantity of water, 
carefully supplied, they will readily strike root. Those which are increased by 
division, such as the Delphiniums, Spiraea filipendula, &c, should be separated as 
early as possible in spring after the severe frosts have ceased, and the exterior 
portions of the plants should invariably be chosen for forming new ones, as these 
are always the most healthy and vigorous. 
Such plants as Daisies, Primroses, Polyanthuses, &c, which easily degenerate, 
ought to be divided every season, or at least every other year, and shifted to a 
fresh spot ; for there is nothing so beneficial to them, or that preserves them so well 
against deterioration, as this frequent removal. 
Wallflowers, Snapdragons, and many others which flower twice in the season, 
should have their old blossoms picked off as soon as they begin to decay ; as, 
besides promoting their future productiveness, this tends much to invigorate the 
plant and recruit all its energies. 
The Helianthemums and Lotus corniculatus are beautifully adapted for growing 
on rock-work, or on narrow borders on which a few pieces of ornamental rock are 
scattered. To increase the double Stocks, it is a common practice to save seed from 
those rich and true-coloured single ones that happen to be growing near the best 
allied double ones, and when the seedlings make their apppearance, to discard all 
the strongest and tallest of those which first present themselves, as these are 
generally single. 
We have thus hurriedly gone over the principal plants in our list, and we have 
now only to suggest, that the remainder of them are all more or less allied to some 
of those to which we have specifically alluded, and, by this palpable resemblance, 
it will be easy to ascertain to which of those their treatment should be assimilated. 
We have not entered largely into the question of their culture, because it is mostly 
of such a simple kind that no farther directions are needed.

Barnade'sia ro'sea. "The singular genus Barnadesia consists of South American spiny 
bushes, with so very similar a foliage that they can hardly be distinguished ; but differing in the 
size and form and number of their flower-heads." The present one, obtained through "the 
kindness of his Grace the Duke of Northumberland, is of the greatest rarity." It differs from 
the other species in not having monadelphous stamens, nor " a solitary tubular flower in the disk ; 
in the place of the latter there is a space which pours forth honey in abundance. It also appears 
that the hairs of the receptacle are not twisted spirally as in other Barnadesias, but are soft and 
straight. It is a warm greenhouse plant, and should be kept during winter in an intermediate 
house, between a stove and greenhouse, where the temperature averages 74°, or as near as 
possible. It may be grown in a compost consisting ot loam, peat, and sand, in equal proportions,"
