 or at tho root?, will cause the leaves to drop, and prevent 

 any growth being made, in whicli case the plant ought to 

 be lowered. If the stems have emitted but few roots, a 

 ring of moss fastened round the stems, and kept constantly 

 wet, will induce the plant to throw out additional roots, 

 when the lowering may be proceeded with. To keep the 

 plants free from insect pests, frequently sponge the foliage. 

 Thrips generally prove very troublesome, and a moderate 

 fumigation is needful, dislodging the insects that may be 

 secreted low down in the centre of the plant, shortly before 

 the operation, by dropping a little weak tobacco water or 

 sulphur among them.

ANGUIiOA (commemorative of Angulo, a Spanish 

 naturalist). Ord. Orchidacece. A small genus containing 

 about sis species. The flowers, which are large and 

 beautifiU, are borne singly on scapes from 12in. to 16in. 

 high, several of which are produced from the ripened 

 pseudo-bulbs of the preceding year's growth. Pseudo- 

 bulbs from Sin. to Sin. high, as thick as a man's wrist, 

 bearing two to thi*ee erect, broad, lanceolate leaves, 2ft. to 

 Mi. long. Temperature, summer, day (maximum), 70deg. ; 

 night (minimum), 60deg. Winter, day (maximum), 60deg. ; 

 night (minimum), 45deg. These are bold growing cool- 

 house plants, best grown in rough fibrous peat, with good 

 drainage. They delight in an abundant supply of water 

 both to the roots and foliage when growing, and require 

 to be kept in a somewhat dark or heavily-shaded place. 

 During the season of rest, and until young shoots commence 

 g^o^vth, they should be kept rather dry. They are pro- 

 pagated by dividing the pseudo-bulbs, just before they 

 commence to grow. The flowering season is summer.

 white ; lip spotted with pink. New Grenada. In other respects 

 similar to above, but is very rare.

 as either of the foregoing, but willi same sized flowers.

 green climbers allied to Momordica. Flowers moncecious ; 

 corolla joined to the calyx, ventricosc, red, with a five- 

 parted spreading border. Fruit somewhat tetragonal.

 but they are rarely seen in oiu' gardens. Some of them are 

 handsome plants, and well worthy of cultivation.
