216 ILLUSTRATIONS OF THE BOTANY OF [ Myrtacee. 
by Dr.Wallich from the Himalayas, D. staminea, Brunoniana, and corymbosa, the first 
figured in P/. Asiat. Rar. 191, and the last in T. 46. p. 2. of the present work. . The 
last is found at the highest elevations, as on Acharanda and Urrukta, and the others 
are common about Mussooree, and every where in the mountains at similar elevations. 
All appear to be suited to the open air of English shrubberies.

76. MYRTACEE. 
The Myrtacee are well known for the elegance of their appearance in tropical coun- 
tries, and from their representative, the common myrtle in temperate climes, but though 
many occur in, they are not confined within the tropics; as several genera and many 
species are found in Australia and New Zealand, as well as at the Cape of Good Hope; 
so, in India, they extend to its most northerly parts along the foot of the Himalaya. 
The genus MJyrtus, in addition to its extension north, spreads south as far as the Straits 
of Magalhaens, and as well as in the cold parts of Peru, occurs in India on the Neel- 
gherries. The other genera, of which species are found in India, are Psidium, Sizygium, 
and Eugenia, common to America and Asia; Jambosa, found in the latter and Africa; 
with Sonneratia and Careya peculiar to India and its islands. ; 
The species of Sonneratia are found only in the Peninsula and the Delta of the Ganges. 
Barringtonia acutangula, sumundur-phul of the natives, existing naturally at Chittagong, 
is found growing in a clump of trees at Saharunpore (probably introduced) near the 
late Mr. Grindall’s house ; but Careya arborea, found in Martaban, and Tenasserim, 
extends naturally as far north as the Jumna, along the foot of the Himalaya, with species 
of Sizygium, as S. Jambolana, a variety called j Jumawa ; S. Panialla ; and another species, 
allied to the first, which occurs still further north in the Suen range, S. venulosum, nob. 
The Myrtacee are chiefly remarkable for secreting volatile oil, which gives an aromatic 
fragrance to the leaves and other parts of many species, rendering these useful as condi- 
ments ; they also secrete tannin, hence the employment of some as astringents ; others 
yield edible fruit, as the guava and the different kinds of rose-apple, which are, however, 
seldom unaccompanied by a degree of aromatic principle, which renders them agreeable 
to some, but disagreeable to others. 
Though naturally growing more to the southward, some of this tribe succeed well in 
the gardens of Northern India, as Jambosa vulgaris, Psidium pyriferum and pomiferum, 
Stzygium Jambolana, and what is remarkable, Melaleuca Cajeputi, though a native of 
the Moluccas. This is probably owing to the quantity of essential oil it contains, as 
well
