large as those of the other species. It appears to have first been 
made known to white men in 1838. A Mr. J. L. Bidwill took 
material of this tree with him to England and there the tree was 
described by Sir William Hooker. 
In its native habitat the tree reaches a height of one hundred feet 
and is now much cultivated on account of its symmetrical shape and 
its whorled branches with spirally arranged leaves ; the latter are 
of one kind, have no leaf stalk and are ovate-lanceolate in outline, 
not quite two inches long, and end in a very sharp point. The male 
catkins are arranged at the ends of the branches, are over six inches 
long and half an inch wide. The fruit cones are exceedingly large, 
twelve inches long and nine inches wide, and cones ten pounds in 
weight occur occasionally on trees in their native land. While they 
have as yet not flowered in Honolulu, they have borne fruit at 
Ulupalakua, Maui, and seeds have been secured there for plantings. 
The aborigines of Queensland call the tree Bunya or Bon-Yi, 
and eat the nuts, of which they are very fond. The wood is of a 
pale color and is used for similar purposes as that of the Hoop Pine. 
CLASS ANGIOSPERMAE 
Covered-Seeded Plants. 
This class includes all plants whose seeds are contained in a 
closed fruit, which is very various in structure and form. The 
largest number of trees belong to this class. They are again made 
up of two subclasses: 1. Monocotyledones, in which the embrionic 
plant within the seed possesses but a single leaf; the leaves are parallel- 
veined as in the banana, and gingers. II. Dicotyledones, in which 
the embryo has two seed-leaves ; the leaves are pinnately or palmately 
veined. 
Subclass Monocotyledon es. 
This subclass is distinguished by the simplicity of the stem- 
structure, the fibro-vascular bundles are arranged in a single column 
without a pith or medullary rays. There are no rings or radiating 
markings in the wood. A bark is absent, the outer portion being of 
the same structure as the inner, with the exception that the bundles 
are closer and more compact. Most of the plants belonging to this 
class are herbaceous, as for example, the grasses, bananas, lilies, etc., 
The Pandani and Palms are the arborescent species represented in 
our introduced flora.
