May.~\ HOT-HOUSE OF REPOTTING, etc. 1G7 



Jambbsa vulgaris, which flowers and fruits freely in our hot- 

 houses. The fruit is about an inch in diameter, eatable, and 

 smelling like a rose, hence called " Rose Apple." The petals 

 of all the species are simple, and may rather be considered 

 the calyx; the beauty of the flowers is in the many erect 

 spreading stamens, either straw, white, rose, or green colour. 

 J. malaccensis, Malay Apple, is greatly esteemed for the de- 

 lightful fragrance of its fruit. We frequently see J. purpu- 

 rdscens, which is a native of the West Indies, going under J. 

 m., which is an Asiatic species, with white flowers and entire 

 oblong leaves ; whereas, the leaves of J. p. are small, ovate, 

 acuminate; the young shoots and leaves are purple. J. ma 

 crophylla, white, and J. amplexicaulis, green, have very long 

 oblong, lanceolate leaves, and are of a strong, woody habit. 

 They are all easy of culture. (Soil No. 11.) 



Jasminum, Jasmine, is a favourite genus of shrubs for the 

 exquisite fragrance of its flowers, of which none are more 

 delightful than J. sdmbac or Arabian Jasmine. There are 

 two other varieties of it, J. s. multiplex, perfectly double ; 

 and J. s. tri/oliatum, double Tuscan Jasmine or Grand 

 Duke; J. s. Maid of Orleans, large, very double, like a very 

 perfect white rose, and exquisitely fragrant. There is also a 

 semi-double variety in cultivation. J. multiflbrum is a pro- 

 fusely flowering and beautiful species. There are several 

 others, all with white flowers, and generally easy of culture 

 (Soil No. 11.) 



Jdtropha, Fhysic-nut, is a genus of six strong-growing 

 shrubs, natives of the West Indies. ./. multifida and J. 

 panduroefblia have the handsomest foliage, and both have 

 scarlet flowers ; the appearance of the foliage of this genus is 

 the only object : the flowers are small, in coarse disfigured 

 panicles, and several of the species have not been known to 

 flower in artificial cultivation. The seeds of J. curcas are 

 often received from the West Indies ; the leaves are cordate, 

 angular and smooth. J. manihot, now Manihot cannabXna, is 

 the Cassada root, the juice of which, when expressed, is a 

 strong poison. They are all easy of culture; want of strong 

 heat in winter will make them cast their leaves, but does them 

 no other injury. (Soil No. 17.) 



Justicia. A few species of this genus are fine showy hot- 

 house plants. J. camea, flesh-colour flowers in large spikes, 

 very fine, blooming nearly the whole season. J. coccinea hai
