or at the roots, will cause the leaves to drop, and prevent 

 any growth being made, in which 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.

 Sin. to 4in. long ; peduncle slender, a little longer than the spur,

 flowering orchids. 



A. virens (green). An inferior variety of A. eburneum. 

 ANGULAR. Having angles, or forming angles. 

 ANGUIiOA (commemorative of Angulo, a Spanish 

 naturalist). OED. Orchidece. A small genus containing 

 about six species. The flowers, which are large and 

 beautiful, 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 three erect, broad, lanceolate leaves, 2ft. to 

 4ft. long. Temperature, summer, day (maximum), 70deg. ; 

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

 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 

 growth, 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. 



A. Clowesli (Clowes's).* fl. fragrant ; sepals and petals concave, 



clear golden yellow ; lip pure white ; whole conformation globular, 



or tulip-like. Columbia (at 5000ft. to 6000ft. elevation), 1842. 



This is the largest growing species, of which there are one or two 



rare varieties. 

 A. eburnea (ivory-flowered).* /., sepals and petals of the purest 



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



similar to above, but is very rare. 

 A. Ruckeri (Rucker's).* fl., sepals and petals yellow, with crimson 



spots ; lip deep crimson. Columbia, 1845. Not so large a grower 



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

 A. B. sangninea (bloody).* This variety has flowers of a deep 



blood red colour, but is rare. 



A. superba (superb). Synonymous with Acineta Iluinboldtii. 

 A. nnlflora (one-flowered).* fl. sub-globose, pure white, some- 



times freckled with brown, spotted profusely with pink inside. 



Columbia, 1844. One of the best in cultivation. 



AlTCrURiIA (one of the Greek names for the cu- 

 cumber). OED. Cucurbitacece. A stove genus of ever- 

 green climbers allied to Momordica. Flowers monoecious ; 

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

 parted spreading border. Fruit somewhat tetragonal. 

 Several species have been introduced from time to time, 

 but they are rarely seen in our gardens. Some of them are 

 handsome plants, and well worthy of cultivation.

ANIGOZANTHUS (from ono^o, to expand, and 

 anthos, a flower ; in reference to the branching expansion 

 of the flower stalks). SYN. Schwoegrichenia. OBD.
