JTii e species of Casuar tree here represented (sent to Wei- 

 mar originally under the name of Casuarina Equisetifolia 

 Linn.) was, in the year 1810, but a very small shrub, not 

 more than three feet high, and the trunk three-fourths of an 

 inch in diameter. In that year, it was planted in the open 

 air, in good soil, containing a portion of calcareous matter, 

 the substratum of the country being of that nature. It was 

 so placed, as to receive the full influence of the sun in 

 summer, and to be protected from the northern and eastern 

 winds. In the winter it is covered with a temporary build- 

 ing, which is warmed by fire, so as to exclude the frost. 



The present height of the tree is sixteen feet and a half, 

 the circumference of the head is forty-two feet, and that 

 of the trunk nearly twenty inches. Near to the tree above 

 described, is another, which was planted five years ago. It 

 was sent from Paris to Weimar, in a flower-pot, and was 

 then a very small shrub. It has already reached the 

 height of eight feet, and the trunk is nearly two inches in 

 diameter. 



The largest tree has this year flowered, but without pro- 

 ducing any seed, being evidently a dioecious plant. The
