§24 FOREST CULTURE AND 
Aponogeton crispus, Thunberg. — From India to 
New South Wales. The tuberous roots of this water- 
herb are amylaceous and of excellent taste, though 
not large. The same remarks apply to A. monos- 
tachyus, L. fil. 
Aquilaria Agallocha, Roxburgh.—On the mount- 
ains of Silhet and Assam. A tree of immense size, 
probably hardy in our warm forest-valleys. It fur- 
nishes the fragrant Calambac or Agallochum wood, 
known also as Aggur or Tuggur or the Aloe-wood of 
commerce, famed since ancient times. The odorous 
portion is only partially distributed through the stem. 
This wood is also of medicinal value. 
Aristotelia Macqui, l Heritier.— Chile. The ber- 
ries of this shrub, though small, have the pleasant 
taste of bilberries, and are largely consumed in Chile. 
The plant would thrive in our forest-valleys. 
Avicennia officinalis, Linné.— From the coasts of 
South Asia to those of South Africa, all Australia and 
New Zealand. It is proposed by Dr. Herm. Behr to 
plant this tree for consolidating muddy tidal shores. 
Berberis buxifolia, Lamarck. — From Magellan’s 
Straits to Chile. This bush, according to Dr. Phil- 
ippi, is the best among the South American species 
for berries, Which are comparatively large, black, 
hardly acid, but slightly astringent. In Valdivia 
and Chiloe they are frequently consumed. 
Brachychiton acerifolium, F. v. Mueller.—The East 
Australian Flame-tree. An evergreen shade-tree, with 
magnificent trusses of crimson blossoms. Like B. po- 
pulneum, R. Br., eligible for promenade-lines, when 
celerity of growth is no object, The mucilaginous sap, 
when exuded, indurates to a kind of Tragacanth,
