regions. A large tree, with timber of good quality. Foliage 
deciduous. 
Hydnum imbricatum, Linne. 
In pine forests of Europe. A wholesome mushroom of delicious 
taste, which we should endeavour to naturalize in our pine 
plantations. Other recommendable European species are : — 
E. erinaceum (Pers.), H. coralloides (Seep.), E. album (Pers.), 
E. diversidens (Fries), U. auriscalpium (Linne), E. su$ squamosum 
(Batsch), H. Icevigatum (Sw.), H. violascens (Alb.), H. infundi- 
bulum (Svv.), j U. fuligineo-album (Schm.), H. graveolens (Brot.),

Hymens 0 a Courbaril, Linn6. 
Tropical and southern 'subtropical America. A tree of colossal 
size and remarkable longevity. Timber hard, extremely ponder- 
ous, close grained, used for select wheel work, tree-nails, beams 
and planks in various machinery. A fragrant amber-like resin, 
known as West India Copal, exudes from the stem. The beans 
of the pod are lodged in a mealy pulp of honey-like taste, which 
can be used for food. The possibility of the adaptability of this 
remarkable tree to the warmer parts of Victoria needs to be 
ascertained.
