White Honeysuckle. 
(Natural Order PROTEACE^E.) 
Botanical description.— Genus, Banksia, Linn. f. 
lowers.—Hermaphrodite. 
Perianth. —Regular, or nearly so, straight or curved, the slender tube opening equally or along 
the lower side only; the limb ovoid, oblong, or linear; the laminro remaining long coherent, 
or rarely separating as the tube opbns. 
Anthers. —Narrow, sessile in the concave laminae, the connective thick, usually very shortly 
produced beyond the cells. 
Hypogynous scales. —Four, very thin and membranous (rarely deficient). 
Ovary. —Very small and sessile; style usually longer than the perianth, rigid, curved, and 
protruding from the slit in the perianth-tube until the end is set free by the separation of 
the laminae, and then either straightened or remaining hooked or curved, rarely straight 
from the first and not exceeding the perianth ; the stigmatic end on a level with the anthers, 
of a different texture but smooth, or striate and furrowed, continuous with the style or with 
a prominent rim at the base, the real stigma small and terminal; ovules 2, collaterally 
attached about the middle. 
Fruit. —A compressed capsule, opening at the broad end (or rather outer margin, for the scar of 
the style is lateral) in two hard (often woody) horizontal valve3. 
Seeds .—Usually 2, compressed, with a terminal membranous wing broad and rounded like the 
valves, the seeds separated by a plate of the same shape (the consolidated outer integuments 
of the inner side of the two seeds) free from the ripe seeds, simple (completely consolidated) 
between the nuclei, double (remaining distinct) between the wings. 
Trees or shrubs. 
Leaves. —Alternate, or rarely verticillate, or nearly so; usually narrow, entire, toothed, pinnatifid 
or pinnate, with numerous (rarely few) short teeth lobes or segments, the primary veins 
numerous and transverse, rarely inconspicuous or irregular and the minute reticulations 
numerous on the under surface, with a minute tomentum rarely wanting in the areolae, and 
sometimes white and covering the whole under surface, the upper surface almost always 
glabrous and smooth. 
Flowers. —Sessile in pairs, in dense terminal cylindrical, oblong, or globular spikes, either terminal 
and sessile above the last leaves or rarely lateral or on short lateral branches, each pair of 
flowers subtended by one bract and two lateral rather smaller bracteoles, both bracts and 
bracteoles densely woolly, villous on the sides, the tips glabrous tomentose or villous, either 
clavate and obtuse or truncate, or shortly acuminate, always densely imbricate in parallel, 
spiral, or rarely vertical lines.
