4()4 ODOROGEAPHIA. 



P. purpurea, Euiz et Pavon, Flora Peruviana et Chilensis, ii., p. 

 20, t. 137, is a native of Peru, and there found in gardens. It is a 

 tree of 20 feet in height. The leaves are oblong-ovate, with 

 revolute edges. The flowers are terminal and cymose ; corollas 

 reddish purple, with a yellow, hairy throat, smaller than that of 

 the other species ; they are very sweet-scented, and in Peru are 

 used by the women to ornament their hair. It is considered that 

 P. incarnata and P. tricolor (Euiz et Pav., loc. cit., t. 138 and 

 139), both natives of Peru, are only varieties of P. purpurea, 

 differing in the size and colour of the iiowers. P. hicolor, Euiz et 

 Pav., loc. cit., t. 140, also a native of Peru, is a tree of about 25 feet 

 in height, with oblong, acuminated leaves with flat edges ; flowers 

 corymbose ; corollas cream coloured, with a curved tube, yellow 

 throat and milk-white limb.

 convolutus, Eumph. Amb., vi., p. 35, t. 38. Native of Amboyna, 

 Cliina and Cochin-China. It is a tree of 20 feet in height. The 

 leaves are scattered, lanceolate, acuminated, glabrous, flat, with 

 man}^ transverse veins. The flowers are terminal, in compound, 

 spreading, upright racemes. The corolla is sweet-scented, white, 

 mixed with red outside and yellow inside : tube curved ; segments 

 obovate. Follicles reflexed. 



All the species of Plumieria are of easy culture. Large cuttings 

 of them strike readily. The plants being of a rather succulent or 

 fleshy nature, they require but little water when not in a free 

 fjrowing state. 



Psidium. 



This name is derived from -xjnBLov, the Greek name of the 

 Pomegranate. The Greek name is derived from ^jrLco, " to make 

 small," in reference to the number of the seeds. (The seeds are 

 really not small, Ijut the fruit is small in comparison to the seed 

 content). 



Psidivm is an extensive, but exclusively tropical genus of 

 Myrtacece, consisting of trees or shrubs with opposite, entire,
