low shrub not over twelve inches high. Its peculiar 
screw shaped pods look like bright yellow spikes of 
flowers a short distance away. The plant might prove 
to be a very good hedge or border plant in western 
Texas and Arizona. The pods hang on long after the 
leaves have fallen." (Rose.)

43352. Seeds from Buenos Aires, Argentina. Presented 
by the Director, Botanic Garden. "Tree with very hard 
wood, unequally pinnate coriaceous compound leaves, 
flowers in branched panicles; fruit a samara. The 
products which are extracted from this tree constitute 
the principal resource of the inhabitants where the 
tree grows. It is one of the Argentine woods which, 
exposed to the air, buried in part or entirely, or 
submerged In water, will keep 25 years in good condi- 
tion, as attested by experiments made by the Argentine 
railway with posts, beams, ties, etc. When full-grown, 
the logs are made into beams, ties, telegraph poles, 
etc., and exported in large quantity. The charcoal 
is very compact; and the extract (tannin) is an im- 
portant product. The saw-dust is much used as an as- 
tringent." (Carrasco.)
