AdansonTa, Linn. Dedicated to Michael Adanson, a 
celebrated French botanist. Linn. 16, Or. 8, Nat. 
Or. Sterculiaceoe. The largest tree in the world is 
the Adansonia or Baob^-tree, the tnmk of wTiich 
has been found with a diameter of thirty feet ; but 
its height is not in proportion. “ It is emollient 
and mucilaginous in all its parts. The leaves dried 
and reduced to pow'der constitute Lalo, a favourite 
article with the Africans, which they mix daily 
with their food, for the purpose of diminishing the 
excessive perspiration to which they are subject in 
those climates, and even Europeans find it service- 
able in cases of diarrhoea, fevers, and other mala- 
dies. The fruit is, perhaps, the most useful part of 
the tree. Its pulp is slightly acid and agreeable, 
and frequently eaten ; while the juice is expressed 
from it, mixed with sugar, and constitutes a drink, 
which is valued as a specific in putrid and pestilen- 
tial fevers.” — Hooker, Bot. Mag. 2792. It delights 
in rich loamy soil, and cuttings of the large ripened 
wood, strike best in a pot of sand, in a moist heat 
imder a glass.
