Obs. II. — I have placed Kingia in the natural order 
Juncese along with Dasypogon, Calectasia and Xerotes, 
genera peculiar to New Holland, and of which the two 
former have hitherto been observed only, along with it, on 
the shores of King George’s Sound. 
The striking resemblance of Kingia, in caudex and leaves, 
to Xanthorrhoea, cannot fail to suggest its affinity to that 
genus also. Although this affinity is not confirmed by a 
minute comparison of the parts of fructification, a sufficient 
agreement is still manifest to strengthen the doubts formerly 
expressed of the importance of those characters, by which 
I attempted to define certain families of the great class 
Liliaceoe. 
In addition, however, to the difference in texture of the 
outer coat of the seed, and in those other points, on which I 
then chiefly depended in distinguishing Juncese from Aspho- 
deleag, a more important character in Juncem exists in the po- 
sition of the embryo, whose radicle points always to the base 
of the seed, the external umbilicus being placed in the axis 
of the inner or ventral surface, either immediately above 
the base as in Kingia, or towards the middle, as in Xerotes. 
* My knowledge of this remarkable structure of Xanthorrhoea is 
chiefly derived from specimens of the caudex of one of the larger 
species of the genus, brought from Port Jackson, and deposited in 
the collection at the Jardin du Roi of Paris by M. Gaudichaud, 
the very intelligent botanist who was attached to Captain De 
Freycinet’s voyage.
