which for a time may be tied to an upright stake. It is 

 most convenient thus to train them until the plants are strong 

 enough to be put into large pots for flowering, because after 

 the cylinder trellis is brought into use it is very inconvenient 

 to have to re-train the plants in consequence of their branches 

 becoming intertwined. By the time they have filled a five- 

 inch pot with good healthy roots they may be put into a large 

 pot of a foot or fifteen inches in diameter, if this be during 

 the period between February and the beginning of August, 

 From August to February it is better to avoid shifting the 

 plants into so large a body of soil. After this sbi.t, with 

 which must be associated thorough drainage, and a rough turfy 

 staple of soil of mixed peat and loam as befoi;, the cylinder 

 trellis may be put down, and the branches trained closely in a 

 spiral manner until the trellis is covered. Occasionally one of 

 the shoots should be taken in a direction downwards, so as to 

 fill up the lower part of the trellis, which is most liable to get 

 bare of branches. The plants while making this growth, 

 which will probably be rapid, should be placed where they will 

 have a free exposure to light with a flow of fresh air, accom- 

 panied by the proper temperature of a plant stove. The 

 genus has been separated from E chiles, and contains some 

 other handsome plants, with tuberous roots and herbaceous 

 annual stems. 



DIPLOCOMA. [Compositae.] A showy half-hardy per- 

 ennial. Common garden soil. Increased by division. 



DIPLOL^NA. [Rutaceae.j A greenhouse evergreen 

 shrub. Soil, two-thirds peat, the rest sandy loam, including 

 one-sixth of sand. Propagated by cuttings in a gentle 

 heat. 



DIPLOPAPPUS. [Compositje.] Hardy or half-hardy 

 perennials, some of them sub-shrubby. Related to Aster. 

 Common loamy soil. Increased by cuttings or by division. 



DIPLOPELTIS. [Sapindacege.] A pretty greenhouse 

 evergreen shrub. Soil, peat and sandy loam. Increased by 

 cuttings. 



DISA. [Orchidaceae.] A genus of teiTestrial greenhouse 

 orchids, natives of the Cape of Good Hope, some of them of 

 great beauty, but scarcely cultivable, so far as experience 

 has yet gone, though worth any further trial. The tubers
