At all times, the pots should be well drained. - The Giganteum strains of the Persian cyclamen produce the largest blooms, but at the expense of quantity. For the average cultivator it is better to try a good strain that is not gigantic. There is a recent departure in the form of crested flowers. Cyclamens come true to color from seeds, and one can now buy named varieties that will reproduce themselves almost to a certainty. - Of recent years cultivators have had much trouble with a tiny pest or mite that attacks the plants and renders them useless for bloom. Its work is done mostly after the plants are taken into the greenhouse and when about to mature into blooming specimens. If the first flowers come deformed or abnormally streaked with colors that are darker in shade, it is a sure indication that the pest is present. Frequent light fumigation with hydrocyanic acid gas as soon as the pest is discovered will in time eradicate it, but being very small, and able to hide under the divisions of the calyx, seldom coming out except on bright days, makes the pest a difficult one to fight. The gas cannot be used during sunshine. Tobacco stems used freely between the pots is a good preventive measure. Greenfly is likely to attack the plants at all stages of growth.

In the frames the plants may be plunged in tobacco stems, and in the greenhouse they must be fumigated or vaporized with some of the nicotine extracts. Great vigilance must be exercised in growing cyclamens. (E. O. Orpet.)

Brilliant rose-red, large. variety purpureum. Purple with bluish markings, large. variety violaceum. Violet-red. variety atro-rubrum and variety splendens. Dark red, large. The variety giganteum (C. giganteum, Hort.) is the common large-flowered, improved form of the florist's cyclamen.

There are also double-flowered forms (R.H. 1886, p. 250); also fimbriate or crested forms, C. Papilio (I.H. 43:63. G.F. 5:235. G.C. III. 21:71; 23:173). Other portraits of C. persicum are: B.M. 44.

The species is frequently figured in the trade catalogues.
