 JV. QUmider, Linn., with broader 1. and larger scentless fl. is a common shrub in tbe 

 Mediterranean region, and Western Asia, as far as Syria and Kurdistan. A third 

 species, N,muscatense^ A. BC, with scented H. grows in Muscat and Southern Persia in 

 dry water courses like the two otliers. These species are supposed to be distinguished 

 by the segments of the corona-lobes. These, however, vary exceedingly, in N. odortim from 

 3 to 7 and in N. Oleander from 3 short triangular to numerous linear or irregular seg- 

 ments. They may be regarded as local forms of one species which extends from the 

 Mediterranean region to China. A number of Indian trees or shrubs of wide distribu- 

 tion bear different names in different countries, such as: Bhus Cotinus {velutina\ 

 Crata^us crenulata (PyracantJia), Alhizzia Julihrissin (mollis)^ Ceplialantlms occidentalis. 

 nmtchoides)^ Cedrus Deodara (Liha?ii, atlmitica).
