by their more sharply-toothed borders, by their somewhat stronger and 
prominent secondary nerves, and by their tertiary ones, which do not run in 
a longitudinal direction. The branchlcts of the secondary nerves partly reach 
the teeth-sinus, and partly form the marginal nerve by their anastomosation, 
a character evidently exhibited by Banksia collina , B. cemula , and B. serrata. 
The living species named show also secondary nerves terminating in teeth. 
The network, represented in Tig. 13a (magnified) is not less developed than 
that of the preceding species. Fig. 14a (magnified) shows the branching of 
the secondary nerves which are divided into craspedodrome and marginal 
branchlcts. 
Locality and Horizon. — Old Rose Valley Lead, with the preceding. 
Banksia myricvEFOlia, sp. nov. 
Plate XIII, Figs. 3, 3a. 
Sp. Char. — B. foliis coriaceis, lineari-lanccolatis, apice acuminatis, 
margine spinoso-serratis ; nervatione brocliido-crospedodroma ; nervo primario 
valido, prominente; nervis secundariis subangulis 65-75° orientibus, tenuibus 
flexuosis approximate ; nervis tertiariis axi folii longitudinali fere parallelis, 
flexuosis dictyodromis ; rete microsynammato. 
Ohs . — Corresponds to Banksia oblongata, Cav., respecting the teeth of 
the margin being approximate and curved towards the apex, as w’ell as the 
network, which is tender and richly developed (see Tig. 3a, enlarged) . But 
it differs from this living species by the leaves being narrowed towards the 
apex, and it approaches Banksia parschlugiana, Ett., from the European 
Tertiary Flora in the same character. 
Locality and Horizon. — Old Bose Valley Lead, with the preceding. 
Banksia lancifolia, sp. nov. 
Plate XII, Figs. 15, 15a. 
Sp. Char. — B. foliis pctiolatis coriaceis, anguste lanceolatis, basi 
acutis, apieem versus sensim attenuate, margine spinoso-serratis ; nervatione 
brochido-craspcdodroma ; nervo primario valido, prominente; nervis secun- 
dariis subangulis 55-65° orientibus, tenuibus subarcuatis, approximatis ; 
nervis tertiariis rectangularibus, dictyodromis ; rete microsynammato 
tenerrimo.
