EUCALYPTUS TREES. 327 
Lupinus varius, L.—The Blue Lupine. Also a 
Mediterranean annual, used like the above cogeners ; 
but a few others are undercultivation as Blue Lupines, 
Some of the American, particularly Californian spe- 
cies, are regarded for agrarian purposes superior to 
the Mediterranean kinds. 
Maclura aurantiaca, Nuttall.—The Osage Orange, 
or North American Bow- wood, or Yellow - wood. 
Texas, Arkansas, Louisiana. This thorny deciduous 
_ Shrub or tree can be well-trained into hedges. It is 
unisexual, and will in favorable localities on rich river 
banks attain a height of 60 feet, with a stem 2 to3 
feet thick, thus becoming available as a timber-tree. 
Here it is recorded as a hedge-plant ; as such our own 
thorny Maclura Calear Galli (Morus Calear Galli, A. 
Cunningh.), of extra - tropical East Australia, which 
moreover possesses small edible fruits, deserves at- 
tention for live fences. Neither of the two is readily 
subject to blight or attacks of insects. The latter pro- 
duées suckers and from the root a yellow dye. ’ 
Maharanga Emodi, A. de Candolle.—Nepaul. The 
root produces, like that of Alkanna tinctoria, a red 
dye. 
Mallotus Philippinensis, J. M. (Rottlera tinctoria, 
Roxburgh.)—South Asia and East Australia, in jungle- 
country, extending into New South Wales. Though 
not of greatimportance, this bush should not be pass- 
ed on this occasion, inasmuch as the powdery substance 
investing the seed-capsules constitutes the Kamala, 
which can be employed not only as an orange dye, 
but also as an anthelminthic remedy. The Hindu 
silk-dyers use it for an orange color, obtained by boil- 
ing the Kamala with carbonate of soda,
