number (when those opposite the petals are imperfect, or shorter than the others) ; 

 filaments subulate, usually free, rarely monadelphous {Erythrochiton), or adherent to 

 the petals [Galipea, &c.) ; anthers introrse, 2-celled, dorsifixed near their base ; 

 cells parallel, opening longitudinally ; connective often prolonged into a glandular 

 appendage [Crawea, Eriostemon, PMlotheca, &c.). Caepels 5-3, rarely 1 {Em- 

 pleurum), sessile or borne on a gynophore, girt with a disk at their base, or buried 

 in this dist, united into a deeply-lobed ovary, lobes distinct, cohering only by the 

 styles ; styles as many as ovaries, springing from their ventral edge, distinct at the 

 base, connate above ; stigmas united in a head, lobed or 3-5 -furrowed ; ovules 2 in 

 each cell, inserted at the middle of the ventral suture, collateral or superimposed. 

 Capsules of 3-5 cocci, distinct or connate at the base, 1-seeded by suppression; 

 epicarp dry, sub-coriaceous, glandular-dotted or muricate ; endocarp smooth, cartila- 

 ginous, often elastic and 2-valved. Seeds oblong or sub-reniform ; testa cartilaginous, 

 smooth ; albumen 0, or fleshy. Embrto usually straight, rarely curved {Almeida, 

 Spiranthera, &c.) ; cotyledons flat or crumpled, enveloping each other, foliaceous in 

 germination ; radicle usually superior, straight or inflexed. 



Tkibe I. EVBI08MEM: 



Fertile stamens equal in number with the petals, often alternating with as 

 many staminodes, inserted below the free edge of a disk which lines the calyx- 

 tube. Carpels 2-ovuled. Testa coriaceous or sub-crustaceous. Embryo exal- 

 buminous, straight. — Heath-like shrubs with alternate or opposite simple coria- 

 ceous small and imbricate leaves, rarely trees with large leaves (Galodendron) . 



Tribe II. BOBONIE^. 



Stamens hypogynous, double in number to the petals, and all fertile, rarely 

 equal and perigynous (Zieria). Disk free, cupuliform or annular, sometimes in- 

 conspicuous. Testa crustaceous. Albumen fleshy. Embryo straight, cylindric. — 

 Shrubs, rarely trees. Leaves simple or 3-foliolate or pinnate.

Tribe III. GVSPARIEJJl. 



Flowers often irregular, corolla often tubular. Stamens 5, some often imper- 

 fect, sometimes hypogynous, sometimes connate, or adnate to the corolla. Disk
