 acece. A genus, comprising some splendid and 

 . curious shrubs, requiring the same treatment,

Disocactus, Lindley. From dis, two, isos, 

 equal, and cactos. Linn. 12, Or. 1, Nat. Or. 

 Caclacece. This was formerly referred to Cereus, 

 from which family it may, however, be readily 

 known by the number of sepals being con- 

 stantly twice two, and that of the petals the 

 same. It was introduced by George tire Skin- 

 ner, Esq., in 1839, to Sir Charles Lemon, 

 Bart., M.P. It forms a graceful bush, from 

 two to three feet high, but will, no doubt, at- 

 tain a much larger size if trained against a 

 trellis, and sufficient room allowed for it to 

 spread ; the flowers are of a deep pink colour ; 

 only one flower is produced at the extremity 

 of each branch, hut they open in succession for 

 a considerable time, and are succeeded by beau- 



tiful little blood-coloured berries, scarcely so 

 large as the common sloe. A turfy loam, mixed 

 with sharp sand and leaf mould, suits it best ; 

 when the plant is growing, a moist atmosphere 

 is most suitable, but in winter it should be 

 kept dry, with plenty of light. It may be in- 

 creased by cuttings or seeds. Synonymes: 1,
