Part II. IBERIDELLA—IBERIS. 231 



IBERIDELLA ■RO'SXi^'DTEO-iSLK.— Round-leaved I. 



A DISTINCT spreading plant, rarely more than a few inches 

 high, and producing pretty, rosy-lilac, sweet-scented flowers in 

 abundance in April, May, and June. The leayes, are thick, 

 smooth, leathery, and of a glaucous olive-green, aiid the flowers 

 are produced in short racemes or corymbs, and usually attain 

 a height of from three to six inches. Flowering , with the 

 vernal Gentian, the Bird's Eye and Scotch Primroses, the alpine 

 Silene, and the little yellow Aretia, it is admirable for association 

 with such plants. It grows naturally very high on the Alps, but 

 thrives in loamy soil on rockwork, does not seem difficult to 

 cultivate, and is easily raised fron> seed. A native of the Alps 

 of Switzerland, Savoy, and Austria. It is occasionally found 

 with white flowers in a wild state. Dr. Hooker has recently 

 figured this plant in the ' Botanical Magazine ' from specimens 

 received from Zurich. This would seem to be a distinct variety 

 from that which I have seen elsewhere, having numerous pale- 

 lilac flowers, with yellow eyes, borne in stout crowded racemes, 

 whereas those of the form introduced by Mr. Jas. Backhouse have 

 the flowers somewhat larger, but in lax few-flowered heads. 

 = Thlaspi rotundifolia.

 IBERIS CORIFOLIA. — Coris-leaved Candytuft. 



A VERY dwar^ kind, about half the size of Iberis sempervirens, 

 attaining a height of only three or four inches when in flower, 

 and perfectly covered with small white blooms early in May. 

 Few- alpine plants are more worthy of geneiral culture, either on 

 rockwork or in the mixed border, for the front rank of which it 

 is admirably suited. It is probably a small variety of the Ever- 

 green Candytuft, but for garden purposes it is distinct enough. 

 A native of Sicily, and probably of other parts of Southern 

 Europe, easily propagated by seeds, cuttings, or divisioii, and 

 thriving in any soil. 



IBERIS COB.B.'EMFOliXA.—Correa-teaved Candytuft. 



This plant is now becoming very popular in London gardens, 

 and generally goes by the name of /. gibraltarica, from which 

 it is quite distinct. It is readily known from any other cul- 

 tivated species by its entire and rather large leaves, by its 

 compact head of large very white flowers, and by flowering later
