nd ourJtg. 1098., Is ■ tendriled climber, well known tor 



the rapidity of its growth, the fine glaucous green of its smooth 



leaves and shoots, and the beauty of its large, solitary, axillary, 



nodding Bowers, with bell-shaped violet or purple corollas, and 



its large, Otal, pendent fruit Plants should either be raised in 

 autumn, and preserved in a pit, and turned out in spring (which 

 is the general practice about London), or they may be sown in 

 Bring, and brought forward in a hot-bed. In mild winters, 

 plants, in dr\ soil, against B conservative wall, maybe preserved 

 alive by covering them with mats. A plant of Cobiv\i scandens 

 against the veranda at the Castle Inn at Slough, in ISOfi, is said 

 to have extended its shoots upwards of 100 ft., on each side of 

 the root, in one season. Astonishing effects might be produced 

 by tins plant in a single season, if it were thought desirable to 

 incur a little extra expense. By preparing a large mass of turfy 

 loam well enriched with leaf mould, or thoroughly decomposed 

 manure, and by mixing this mass with a quantity of small sand- 

 stone."., as recommended by Mr. M' Nab for the culture of the genus 

 Srlca, a large fund of nourishment would be produced. Now, st*^ 

 in order that this nourishment might be rapidly imbibed by the *>\ I 

 roots, it would be necessary to supply it with bottom heat early 

 in the season, and with liquid manure from a surrounding 

 trench, three parts filled with that material, during the whole 

 summer. A plant BO treated would cover several thousand 

 square feet of surface, either of wall, roof, or of the open ground, 

 in one season.

 TO THE ORDER CONVOLVULA V CEiE. 



There are a few species of Convolvulus which are technically considered shrubby; and, though 

 for all practical purposes they may be treated as herbaceous plants, we shall, for the sake of those 

 who wish to gather every thing into an arboretum that can be included in it, here notice two or 

 three ||
