MISSOURI BOTANICAL GARDEN BULLETIN 95 
which frequently obtain in this vicinity. They are adapted 
to both sun and shade, and the Scotch laburnum, L. alpinum, 
which flowers two or three weeks later than L. anagyroides, 
is said to be even hardier than this latter species. The young 
flowers are reported to be poisonous if taken internally, and 
it is probable that all parts of the tree contain some toxic 
principle. The hard, tough, and closely grained wood is 
susceptible to a very high polish and in Europe is manufac- 
tured into various small articles. Plants may be raised from 
seed, but this practice is not advised since it frequently 
results in most inferior trees. Small trees propagated by 
budding, grafting, or layering should be easily obtained from 
reliable nurserymen who sell them under various horticul- 
tural names.
