CASUARINA equisetifoua (S.P.I. Nob. 9818, 19386, 29178, 30380), a 
tall tree or often headed back to a hedge, is the most abundant species 
here and abroad, though it is not grown in the Gulf States or northern- 
most Florida with much success, and in California too it is not the hard- 
iest species. It is the bark of this tree that is the most used medici- 
nally, and the fuel value of the wood, together with the tannin properties 
of this species, makes it distinctly valuable. Its ornamental qualities 
are exceeded by those of other species, and it is possible that it has 
been planted to the exclusion of its more beautiful relatives, but it is 
undoubtedly useful upon barren sands and salt-sprayed coral rocks. Dis- 
tinguished by thick round branchlets. 
casuarina torulosa (Nob. 1304, 1866, 15689, 18686, 49854) is fair- 
ly commonly grown in the same range as the preceding species. It does 
not differ markedly in ornamental worth. In Australia it is considered 
a good fuel and lumber tree. Distinguished by square branchlets. 
casuarina suberosa (Hos. 12796, 56564) is a rare tree in southern 
Florida. The forage it provides in Australia is particularly good. 
The branchlets are very slender. 
CASUARINA STRICTA (Nos. 1863, 1864, 8254, 15688, 18687, 30379, 
44909, 46882, 46883) a favorite in California, seemingly more rare in 
Florida, is a fairly hardy species making a low, often shrubby growth. 
It is conspicuous on account of its very thick, often pendulous branch- 
lets and frequently very big cones - when mature, larger than those of 
other species. In appearance it is not so elegant as some other sorts, 
and it is occasionally rated as a coarse plant, but it is very striking 
and for its reputation can fall back on its economic worth. The branch- 
lets are said to be a favorite forage of Australian cattle and are the 
chief source of the Casuarina fiber which has been mentioned. For 
shingles and posts the wood is especially sought. 
casuarina GLAUCA (Nos. 1862, 38147, 42286) is cultivated in south- 
ern Florida. In its native home it is accustomed to salty inundations, 
and this fact may augur a future upon the Everglades. Its graceful 
branchlets possess a beautiful blue-green cast and are very long and 
often pendulous. For ornamental charm this elegant tree may well be 
considered the best of the genus. The wood makes especially fine 
shingles and the bark yields a promising percentage of tannin. This 
tree suckers and sprouts from the base, and stands trimming. It may 
therefore be used for hedges if desired. 
casuarina SUMATRANA (Nos. 37119, 45659, 54705), a native of the 
Dutch East Indies, has had a difficult time establishing itself in this
