In B. ijaludosa this feature is very much less present, and often 

 entirely wanting; when the segments split both they and the 

 styles appear to be of the same length. 



The only other Port Jackson species closely related to it is B. 

 marginata, but here again the differences are very pronounced. 

 Its young branches are very villous. The secondary veins of the 

 leaves, if looked at carefully in a strong light, will be seen to be 

 straight, fine, and quite. parallel, while their teeth are also longer, 

 more slender, and sharper than in B. paludosa. Their shape also 

 is decidedly oblong. 



The styles also of B. marginata are very much longer, and as 

 in the case of B. integrifolia, stand away from the split corolla- 

 segments a long distance, nor are they straight, but decidedly 

 bent. The tips of the corolla-segments are also almost acuminate. 



The only description of the cones of B. paludosa we can find 

 is by Meisner, in DC. Prod. xiv. 457 : — -" Folliculi valde com- 

 pressi, circ. semipollicares, lana rufa hirsuti, margine glabres- 

 centes." 



But we are of opinion that the cones thus described are pro- 

 bably those of our vai-. minor of B. latifolia; they certainly do 

 not apply to B. paludosa. 



In reality the cones of B. paludosa are not very dissimilar to 

 those of .5. integrifolia, and alone furnish a strong argument for 

 the close affinity of the two species. In B. integ^-ijolia the 

 fruitlets dehisce at an early stage; in B. paludosa the reverse is 

 the case, according to our observations. At present we are 

 inclined to attach some practical importance to this in the dis- 

 crimination of cones obviously so closely allied. 



We have been exercised in deciding for ourselves whether B. 

 paludosa is a true species or only a variety of B. integrifolia, but 

 it is worthy of note that there is what may be termed the 

 2Jaludosa type, having varieties of its own, readily distinguishable 

 from B. integrifolia, which is in reality one of the most distinct 

 species of the genus. B. integrifolia has been considered far 

 more protean than it really is by having other species constantly 

 confused with it, and it is one of the objects of this paper to
