 Xative of Siberia. The height of this plant is about 9 inches. 

 Its lower leaves are stalked, lanceolate, runicate, bluntish, upper 

 leaves sessile, ovate, acuminated, coarsely-toothed at the base. 

 Flowers purplish. 



The other section of Hesperis is known as Deilosma, from SeiXr}, 

 the day, and ocrfir), a smell. The flowers of the plants belonging 

 to this section smell in the day-time as well as at night (D.C., 

 Syst., ii., p. 448, and Prodr., i.,p. 188. The most commonly known 

 species is IT. matronalis (Lam.. Diet., iii., p. 321, and 111., t. 564, f. 1). 

 This is the common garden Eocket, a very variable plant of from 

 1 to 4 feet in height. Many of its varieties are in cultivation. It 

 is a native of coppices and hedges nearly throughout the whole of 

 Europe, but is probably not indigenous to Britain. The pedicels 

 are the length of the calyx ; petals obovate, pods erect, torose, 

 smooth, not thickened at the edge; leaves ovate-lanceolate, toothed. 

 Of this species there are several varieties, both single and double, 

 and in numerous colours. 



H. Grandiflora, Bot. Mag., t. 2683, is a fine plant of 3 feet in 

 height ; probably a native of Hungary. There are numerous other 

 well-marked species and A^arieties, but of less importance as 

 regards their perfume. 



The perennial species of this genus thrive best in a light rich 

 soil, but they require to be frequently transplanted and divided, 

 otherwise they will not long exist, particularly the double varieties 

 of H. matrGiialis ; the best time to do this is after they have 

 flowered and when again Ijeginning to spring afresh from the root ; 

 also if the flower stems are well cut down before they are much 

 exhausted by the bloom, a good stock of off-sets will Ije produced. 



The biennial and annual sorts do well in any common garden 

 soil, requiring the same treatment as other hardy annuals and 

 biennials.
