plants. But the difficulty occurs in those genera which 
have an increased number of lobes on each squama, as 
Agathis and Araucaria, where their number is considerable 
and apparently indefinite, and more particularly still in Cun- 
ninghamia, or Belis in which the lobes, though only three 
in number, agree in this respect, as well as in insertion and 
direction, with the ovula. The supposition, that in such 
cases all the lobes of each squama are cells of one and the 
same anthera, receives but little support either from the 
origin and arrangement of the lobes themselves, or from 
the structure of other phaenogamous plants ; the only cases 
of apparent, though doubtful, analogy that I can at present 
recollect occurring in Aphyteia, and perhaps in some Cu- 
curbitaceaa. 
That part of my subject, therefore, which relates to the 
analogy between the male and female flowers in Cycadeae 
and Coniferse, I consider the least satisfactory, both in 
regard to the immediate question of the existence of an 
anomalous ovarium in these families, and to the hypothesis 
repeatedly referred to, of the origin of the sexual organs of 
all phaenogamous plants. 
In concluding this digression, I have to express my 
* In communicating specimens of this plant to the late M. 
Richard, for his intended monograph of Coniferse, I added some 
remarks on its structure, agreeing with those here made. I at 
the same time requested that, if he objected to Mr. Salisbury’s 
Belis as liable to be confounded with Beilis, the genus might be 
named^ Cunninghamia, to commemorate the merits of Mr. James 
Cunningham, an'excellent observer in his time, by whom this plant 
was discovered’; and in honour of Mr. Allan Cunningham, the 
very deserving botanist who accompanied Mr. Oxley in his first 
expedition into the interior of New South Wales, and Captain 
King in all his voyages of survey of the Coasts of New Holland.
