reference to the leaves of B. collina : — " Note that there is a 

 good deal of variation in the margin of the leaves — exception- 

 ally, they may be entire " (" F. Fl. of N.S.VV.," vol. iv., part 8). 



The specimens shown of B. collina, collected by myself in 

 the Emerald district, Victoria, match those of B. spinulosa 

 collected by Mr. R. T. Baker, F.L.S., about i8 miles south of 

 Sydney, and also that figured in the " Forest Flora of New 

 South Wales," vol. iv., part q. 



The original descriptions of the two species are given for 

 comparison, to which, from observations made during a 

 number of years, I have been able to add some further 

 characters. I have also included notes given by Bentham and 

 I. H. Maiden in their respective writings. A description of 

 the seedlings is also given, with the synonymy of the com- 

 bined form. 



B.\NKSi.\ SPINULOSA, Smith.

 bordered towards the end with 

 two or three small teeth on each

 volute margins and the midrib 

 prominent underneath, 1 1 to

 ing the white under surface, 

 with dentate margins, as in B. 

 collina— P. R. H. St. J.] 

 Spikes.— Ovoid. 2 to 3 inches long, 

 or rarely cylindrical and twice 

 as long' [more usually cylind-

 lUatla. — With broad, shortly acu- 

 nunate, silky pubescent ti])s.

 I inch long. 



Slylc. — I {■ to 1'. inches long 

 [hooked— I'. K. H. St. j.]. 

 often purple, with a short

l-'ruitins Cone. — Cylindrical . 



Capsule. — Scarcely protruding, 

 glabrous [thick and smooth — 

 Bentham, " V\. .\us.," v., 547]. 



Banksia collina, R. Brown. 



(Trans. Linn. Soc, x., 204, i8oy.) 



.\ tall, erect shrub, attaining 8 

 to 10 feet ; the young branches 

 tomentose or villous. 

 Leaves. — Linear [and narrow 

 linear— P. R. H. St. J.], much 

 broader than in J3. spinulosa, 

 and always [not always — 

 P. R. H. St. J.] showing the 

 white under surface, the margins 

 recurved, more or less denticu- 

 late or rarely quite entire, i^ to 

 3 inches long. 



Spikes. — Oblong or 

 to 6 inches long. 



cviindrical, 3 



Bracts. — Witli broad, Hat, or 

 scarcely acuminate ends [silky 

 pubescent lips— P. R. H. St. J. J 



l-'lowcrs. — Yellow or dark i)urple. 



I'rrianlh. — Silky, 1 inch long.

I'ruiting Cone. — Cylindrical like 

 B. cricifolia. 



Capsule. — Thick and scarcely pro- 

 truding ;is in that species (/?. 

 rricifolia) [but quite glabrous — 

 Benth,, " Fl. Aus.," v., 548].
