This CaUitris so far appears to be very local, for after a rather exhaustive 

 survey of the pines it does not appear to occur elsewhere, and there is no indication, 

 at present of any forms really transitional between it and any of the above- 

 mentioned species, whilst it is distinct from any Western Australian CaUitris. 

 Mr. J. H. Maiden ("Forest Flora, N.S.W.," Vol. II, p. 2, p. 55,) expresses an 

 opinion that this species is C. propinqiia ; the results of this investigation, 

 however, show it to be distinct from that species. 



Herbarium Material Examined. 

 Kew, — 



A specimen, labelled Port Phillip, and named by Mueller as C. rohusta, 

 has a resemblance to this species. 



II. SYSTEMATIC. 



This is a tree attaining a height of over 50 feet, with a diameter from i to 

 2 feet, and having a hard, compact bark similar to that of other species of 

 CaUitris. The branchlets are numerous and slender, with decurrent leaves, 

 having a bright green colour ; internodes terete, or with very obtuse angles, the 

 free ends of the leaves being small and acute. 



Male amenta terminal, seldom axillary, solitary, or only occasionally two 

 together, 3 lines long and slightly exceeding the branchlets in diameter, cylindrical, 

 oblong. Stamens in whorls of three, imbricate in six vertical rows ; apex, scale- 

 like, ovate or orbicular, concave, with two anthers (two-celled) at the base. 

 Female amentum about i line in diameter, having six scales, solitary or two 

 or three together, fairly numerous below the terminal drooping branchlets. 



Fruit-cones large, solitary, globular, or compressed globular, from i inch 

 to I J in. diameter, or even larger; valves six, very thick, smooth or slightly rugose, 

 furrowed at the junctions, the three larger ones broadest at the middle and then 

 tapering upwards, and very thick from the base to -the middle, the smaller ones 

 about one-half as wide as the larger and shorter in length; the dorsal point 

 minute and close to the apex. Seeds dark-coloured, the wings varying. in size 

 and shape. 



III. LEAVES. 



{a) , Economic (vide Chemistry). 

 (b) Anatomy. 



One of the chief features of these leaves, is the large epidermal cells of 

 the dorsal surface ; in the ventral channel of the collateral leaves, they take the 

 same form generally observed in the genus — the cuticle developing into elongated
