FLOWEBING TEBBS AND SHBUBS 129 



the flowers are without scent. The leaves, too, are quite 

 glabrous and obscurely toothed. 



P. Lemoinei Boule d'Argent is a cross, raised in 

 1888, from P. Lemoinei and the double-flowered form of 

 P. coronarius. The flowers are double white and with 

 the pleasant, but not heavy, scent of P. microphyllus. 

 P. Lemoinei Gerbe de Neige bears pleasantly-scented 

 flowers that are as large as those of the well-known 

 P. speciosissimus ; while Candelabre and Manteu 

 D'hermine are other desirable kinds. There is an erect 

 form of P. Lemoinei named erectus that is also worthy 

 of note. 



P. Lewisi, from North America (1839), is hardly 

 sufficiently distinct from some of the others to warrant 

 special notice. The flowers are small and arranged in 

 threes. 



P. microphyllus, from New Mexico (1883), is of low 

 growth, and remarkable for its slender branches, small, 

 Myrtle-like leaves, and abundance of small white flowers. 

 It is a decidedly pretty shrub, but is not so hardy 

 as the others. P. microphyllus erectus is of upright 

 habit. 



P; satzumi (syn P. chinensis). — Japan, 1851. A slender- 

 growing species, with long and narrow leaves and large 

 white flowers produced in pairs. 



P. tomentosus (India, 1822) and P. mexicanus (Mexico, 

 1839) are other species that might be worthy of including 

 in a representative collection of these plants. 



This is a valuable genus of shrubs, all being remarkable 

 for the abundance of white, and usually sweet-scented, 

 flowers which they produce. They require no special 

 treatment, few soils, if at all free and rich, coming 

 amiss to them; while even as shrubs for shady situa- 

 tions they are not to be despised. Propagation is effected 

 by means of cuttings, which root freely if placed in sandy 

 soil.
