flowers are white, leaves ovate, elongate, sessile ; flowers 
scarlet, in crowded round corymbs ; is called I. coccinea in 
the Botanical Magazine, by which it is known in our collec- 
tions, and we think is the same as I. stricta. I. fldmmea 
and I. specibsa. I. Pavetta, the flowers are white and sweet- 
scented, the leaves of all the species are opposite ; there are 
a few other species that we are not thoroughly acquainted 
with, but have been thus explicit to prevent error as far as 
possible in this beautiful genus. They are all evergreen, 
low-growing shrubs ; the plants grow best in Jersey black 
sandy earth, but flower most abundantly with Soil No. 10. 
Jambosas, about twelve species, which have been princi- 
pally taken from Eugenia, and contains its finest plants, and 
is a splendid genus of evergreen shrubs. E. Jdmbos is 
now 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 con- 
sidered the calyx ; the beauty of the flowers is in the many 
erect spreading stamens, either straw, white, rose, or green 
colour. J. malacceiisis, Malay Apple, is greatly esteemed 
for the delightful fragrance of its fruit. We frequently see J. 
pit rpurdscens, 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. macrophylla, white, and J. amp>lexicaidis, green, 
have very long oblong, lanceolate leaves, and are of a strong, 
woody habit. They are all easy of culture. (Soil No. 11.) 
Jasmhium, 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. trifoliatum, 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. multi/tdnim is a 
profusely flowering and beautiful species. There are seve- 
ral others, all with white flowers, and generally easy of cul- 
ture. (Soil No. 11.) 
Jdtropha, Physic-nut, is a genus of six strong-growing 
shrubs, natives of the West Indies. J. multifida and J.
