514 FOREST CULTURE AND 
Spondias dulcis, G. Forster.—Fiji, Tongan, and So- 
ciety Islands. This noble tree is introduced into this 
list to indicate that trials should locally be instituted 
here, as regards the culture of the various good fruit- 
bearing species of this genus, one of which, 8. plei- 
ogyna, F. von Mueller, transgresses in East Austra- 
lia the tropical circle. The lamented Dr. Seemann 
saw S. dulcis 60 feet high, and describes it as laden 
with fruit of agreeable apple-flavor, called Rewa, and 
attaining over 11 pounds weight. 
Streblus asper, Loureiro.—South Asia. This bears 
a good recommendation for live fences, it being a 
shrub of remarkable closeness of branches. 
Swietenia Mahagoni, Linn¢.—The Mahogany-tree 
of West India. The degree of endurance of this fa- — 
mous tree is not sufficiently ascertained. In its native 
mountains it ascends to 3,000 feet. 
Synoon glandulosum, A de Jussieu. —New South 
Wales and South Queensland. This evergreen tree 
deserves cultivation in sheltered, warm, forest-valleys 
of our colony, on account of its rose-scented wood. 
Some species of Dysxoylon, of East Australia, produce 
also rosewood. 
Tagetes glanduligera, Schranck. —South America. 
This vigorous, annual plant is said by Dr. Prentice to 
be pulicifugous. 
Tamarix articulata, Vahl.—North and Middle Af- 
rica, South Asia. Of similar utility as T. gallica. The 
same or an allied species extends to Japan. 
Tamarix Germanica, Linné.— Europe and West 
Asia. Likewise available for arresting the ingress of 
shifting sand, particularly in moist places ; also for 
solidifying precipitous river-banks,
