country. Its only future as* an out-door plant probably lies in southern 
Florida. The: square-, 'thick, forking branchiets, unlike those, of other 
specie©, are of a lustrous, dark green which, combined with the thick, 
bushy, pyramidal growth adapted to pet culture-, may give it the place 
in the Tropics that box holds in the North. For growing in pots it 
should have a light vegetable mold and peat with a small quantity of 
sand; it is then to be placed in wellrdrained pots. Cuttings of the 
young shoots make charming bouquets. This species is the only one of 
those in the United States which is likely to be seen outside of the 
warmer portions; as a pot plant it is appropriate to northern homes 
quite as much as palms, cycads and Ficus. 
CASUAR1NA CUNN1NGHAMIANA (Ho 8. 1860, 1865, 44552, 46861, 47973, 
48155, 49720) is a species with slender branchlets and very small cones; 
it is considerably more elegant in appearance than C. equisetifoUa, though 
often oonfused with it. In Florida it seems not to sucker from- the 
base, and when allowed to reach its full height it grows in Australia . 
to be a very, tall tree with a sturdy trunk which shoots up straight 
and-unbranched. Economically this is probably the most important of 
the genus. Maiden's studies in Australian trees refer to it as one . 
of the tallest, thickest, fastest growing, moet useful and noble trees 
of -the forest. • Its timber ranks high for fuel and more especially as 
construction lumber, since it checks-less than .its relatives.- 
Maiden asserts that this is distinctly a fresh-water tree in Aus- 
tralia; in Florida some specimens are to be seen on the Everglades, 
though not actually in the brackish waters but rather on elevated reefs. 
It seems likely to prove hardier than any other species known in this 
country. 
This Office has recently made a canvass of all the experimenters 
who have received plants of Casuarina cunninghamiana. Forty replies were 
returned from ten states, Only one- experimenter expressly rated this? 
species as inferior to the others, and almost half of the answers, 
showed that it was a favorite. There were some losses of trees through 
causes. bearing no relation to hardiness, but -a large number. of data 
were secured concerning their resistance to cold. 
R. S. ; ElUQt, of Kerman, Calif., says, "This, is one of the finest 
Caauarinas I have seen, better than Casuarina equisetifoUa or C. strict^,? , 
Temperatures there have reached 11° F. since the plants were. set out. 
E. 0. Orpet writes from Santa Barbara, .Calif , , where the plants 
have endured 25® J* , "Probably .the best of the Casuarinae." . 
Harold Mowry,. of Gainesville, Fla., reports, on Professor Rolf's 
Slants that qnly the tips were injured by 20° F., a damage so slight . 
that a careful examination was required to find it. 
Paul Popenoe, of Coachella, Calif., reports that his trees have 
withstood excessive, heat, .drought, wind, and temperatures of 25° F. : ,
