468 NATURAL HISTORY OF PLANTS. 
glandular at apex, introrsely rimose; 5 sterile oppositipetalous, 
inserted slightly above disk, long petaloid, sparsely glandular, glan- 
dular at apex. Germen central, long stipitate; cells 5, oppositi- 
petalous, tuberculate, each crowned with conoid gland at apex ; 
ovules 2, descending; micropyle extrorse, superior; style slender, 
inserted at summit of germen, stigmatiferous, entire, not dilated at 
apex. Capsule stipitate, thick, ligneous, subglobose-5-agonal, echi- 
nate, septicidally 5-valved ; endocarp cartilaginous, free, circumcissile 
at margin; seeds subhorizontal; testa crustaceous; embryo exal- 
buminous ; cotyledons conferruminate, thick, fleshy, oily; radicle 
minute.—A lofty pellucid-punctuate tree ; branches decussate, oppo- 
site or 3-nate; leaves decussate, petiolate, acutely crenulate, parallel 
nerved; flowers in terminal compound cymiferous racemes’ (South 
Africa). 

IV. BORONIEZÆ. 
26. Boronia Su.—Flowers 4-merous ; receptacle rather convex 
or concave. Sepals free or connate at base, decussate-imbricate. 
Petals 4, alternate, scarcely unguiculate, imbricated. Stamens 8, 
2-seriate, hypogynous or perigynous, inserted without glandular 
disk ; filaments free, glabrous, ciliate, tuberculate or glandular below 
apex, more rarely pilose ; the oppositipetalous sometimes antherless ; 
anthers ovate or cordate, muticous at apex or sometimes produced in 
various appendices, introrsely 2-rimose. Carpels 4, oppositipetalous, 
surrounded at base by disk ; germens free, 2-ovulate ; ovules descend- 
ing, collateral or superposed ; micropyle extrorse, superior ; others 
sometimes ascending ; styles 4, soon coalescing in one, stigmatiferous 
capitate 4-lobed apex. Cocci 2-4, free, 1, 2-spermous, usually solute 
from endocarp, dehiscing. Seeds albuminous ; embryo often terete.— 
Glabrous, pilose or tomentose shrubs, glandular-punctuate or tuber- 
culate ; odour rutaceous ; leaves opposite, simple or 3-foliolate, often 
pinnate ; folioles entire or serrulate, articulate; rachis sometimes 
winged ; flowers axillary and terminal, solitary or cymose; cymes 
simple or ramified; pedicels bracteolate, articulate (Australia). See
