EUCALYPTUS TREES. 469 
species of the Andine genus Styloceras, does it ap- 
pear to be known what relation their wood may hold 
to that of the true box-tree, and whether they are 
more rapid in growth. 
Cesalpinia coriaria, Willdenow. — Wet sea-shores 
of Central America. Might be naturalized in our salt- 
marshes. Colonel Drury states that each full-grown 
tree produces annually about 100 pounds of pods, the 
husk of which, commercially known as Divi-Divi, is 
regarded as the most powerful and quickly-acting tan- 
ning material in India. The mercantile price of the 
pods is from £8 to £13 per ton. 
Cesalpinia Sappan, Linné.—South Asia. The wood 
- furnishes red dye. This shrub can also be utilized 
for hedges. It would likely prove hardy here in pla- 
ces free of frost. 
Cresalpinia sepiaria, Roxburgh.—South Asia, east 
to Japan. Can be utilized inthe warmer tracts of our 
colony as a hedge-bush. It can advantageously be 
mixed for hedge - growth with Pterolobium lacerans 
(R. Br.), according to Dr. Cleghorn. 
Ceesalpinia tinctoria, Humboldt.—Chile. The bark 
yields a red dye. 
Calamagrostis longifolia, Hooker.—North America. 
Excellent for fixing drift-sand. 
Calamintha Nepeta, Hoffmansegg.—Is of the strong- 
est odor among several species, but not of so pleasant 
a scent as C. incana, Boiss., and C. grandiflora, 
Moench. 
Calamintha officinalis, Moench.—Middle and South 
Europe and Middle Asia, North Africa, <A perennial 
herb, used, like melissa, as a condiment, 
Calyptranthes aromatica, St. Hilaire,--Seuth Brazil. 
This spi¢e-shrub would likely prove hardy here ; the
