40 NATURAL IIlS'lUllY OF PLANTS. 



or slightly imbricate, 3-angular. Germen half immersed in rather 

 thick, oftener 5-gonal disk and not confluent with it; cells 2, 

 2-ovulate ; ovules ascending ; a spurious septum more or less deve- 

 loped between the ovules in each cell (hence cells 4, 1-ovulate). 

 Berry subglobose (small) slightly fleshy ; seeds exarillate, externally 

 more or less triate or costate ; embryo small albuminous. — Unarmed 

 shrubs, generally glabrous ; leaves alternate petiolate subovate 

 serrulate, sometimes glandular ; stipules minute, deciduous ; flowers 1 

 in slender axillary more or less compound cymiferous racemes.

22? Frauenhofera Mart. 3 — Flowers nearly of Perrottetia, 5- 

 merous ; sepals and petals imbricate, germen 2-locular ; ovules in 

 cells 2, ascending. Fruit * cylindrical subsiliquiform, conical at apex ; 

 pericarp fibrous coriaceous, 1-locular. Seed 1, suberect, embryo...? 

 — A small softly pubescent tree ; leaves alternate ovate entire or ser- 

 rulate ; stipules very small deciduous ; flowers 5 in axillary and 

 terminal filiform glomeruliferous spikes, bracteolate. (Brazil?) 



23 ? Siphonodon Griff. 7 — Flowers hermaphrodite ; receptacle 

 rather thick cupular. Sepals 5, imbricate. Petals same in number, 

 alternate longer, erect open, imbricate. Stamens 5, alternipetalous, 

 slightly perigynous with perianth; filaments 1-adelphous at base, 

 complanate, incurved at free apex ; anthers basifixed shortly subsa- 

 gittate ; cells marginal oblique linear, subextrorsely rimose. Germen 

 immersed at base in hollow of receptacle and adnate to it ; cells <x> , 8 

 unequally pluriseriate ; ovules in each solitary, ascending; style (?) 

 central (subgynobasically) inserted vertically intruding between the 

 germens, at apex obtuse or subemarginate and surrounded at base 

 with oo ° of unequal papillose squamules. Fruit drupaceous, sparsely
