Seeies II. P0LLICTJLAEE8. 



Fruit dehiscent, follicular or 2-Talvfed, rarely (in Relicia, and 

 Macadamid) drupaceous and indekiscent. Mowers' usually in pairs, 

 with a single bract to each pair, rarely (in Carnarvonia, Lambertia, 

 and Stenocarpus) the inflorescence anomalous. 



Tribe 5. G-EEVTLLEE.a).— Ovules 2 or 4, collateral. Seeds without 

 any intervening substance or separated by a thin lamina or mealy 

 substance. Flowers in racemes or clusters, with deciduous or abortive 

 bracts, or with an involucre of imbricate bracts. Examples : Mac- 

 adamia ternifolia, the Queensland Nut ; Grevillea rolusta, the Silky 

 Oak. 



Tribe 6. EMBOTHBiEiE. — Ovules several, imbricate in 2 rows. 

 Seeds usually separated by thin laminae or a mealy substance. Ex- 

 amples : Stenocarpus sinuatus, the so-called Tulip-flower ; and the 

 white-flowered Protead, so frequently met with in flower on sandy 

 land, Lomatia silaifolia. 



Tribe 7. BANESiEiE. — Ovules 2, collateral. Seeds separated 

 either by a hard usually woody substance, or by a membrane rarely 

 wanting. Elowers in dense cones or heads. Examples : Banlcsia, any 

 species generally known as Honeysuckle trees.

[I was led to choose this genus of ProteacecB to illustrate the mode 

 of describing genera and species, first, on account of its being one of 

 the very few plants named by the younger Linnseus, second, because 

 it bears the name of one. Sir Joseph Banks, who did much to make 

 known the plants of this part of Australia.} 



Elowers 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 laminas remaining long 

 coherent, or rarely separating as the tube opens. Anthers narrow, 

 sessile in the concave iaminse, the connective thick, usually very shortly 

 produced beyond the cells. Hypogynous scales 4, very thin and 

 membranous (rarely dificient?). 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 Iaminse, 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 above the middle. Emit a compressed 

 capsule, opening at the broad end (or rather outer margin, for the 

 scar of the style is lateral) in 2 hard often woody horizontal valves. 

 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 2 

 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 verticiUate or nearly so, 

 usually narrow, entire toothed, pinnatifid or pinnate, with numerous 

 (rarely few) short lobes or segments, the primary veins numerous and
