 and lobos, a pod. Nat. ord. Leguminous Plants [Legumi- 

 nosa3]. Linn. i6-Monadelphia, 6-Decandria. Allied to 

 Hovea.) 



Greenhouse evergreens, from Australia, and orange- 

 flowered, except where otherwise mentioned. Seeds in 

 spring, in a slight hotbed, after placing them several 

 hours in water, at a temperature of 130 ; also by 

 cuttings of the half-ripened short shoots in sand, under 

 a bell-glass, in April ; fibrous, sandy peat chiefly, with

 in winter, destroys them. Winter temp., 40 to 48.

PLEASURE-GROUND is a collective name for that 

 combination of parterres, lawns, shrubberies, waters, 

 arbours, &c., which are noticed individually in these 

 pages. One observation may be applied to all let 

 congruity preside over the whole. It is a great fault 

 to have any one of those portions of the pleasure-ground 

 in excess ; and let the whole be proportioned to the 

 residence. It is quite as objectionable to be over- 

 gardened as to be over- housed.
