IV. PANCOYIE^. 



45. Paneovia W. — Mowers irregular polygamo-dioecioTis ; sepals 

 6, very unequal, imbricate; two exterior smaller. Petals 4 (the 

 fifth, place vacant), unequal, furnished above the claw with a cucul- 

 late scale often cristate-appendiculate at the back or apex, imbricate. 

 Stamens 8, interior to unilateral or semilunar unequally lobed disk ; 

 filaments excentric unequal, often pilose ; anthers shortly exserted, 

 introrsely 2-rimose. Germen eccentric, often stipitate,^ 3-lobed or 

 3-locular ; style slender acute, apex stigmatose entire or ob- 

 scurely 3-lobed ; ovule in cell 1, ascendent; micropyle extrorsely 

 inferior. Fruit 1-3-coccous to base ; cocci 1 , 2 sometimes abortive 

 minute ; the fertile ones oblong or subcylindrical, sometimes obovoid 

 divaricate, 1 -sperm ous. Seeds ascendent exarillate ; testa mem- 

 branous or crustaceous ; cotyledons of exalbuminous embryo straight 

 or arcuate thick ; radicle straight or more rarely curved incumbent. 

 — Erect trees ; leaves and inflorescence tomentose ; leaves alternate 

 exstipulate, and abruptly imparipinuate ; leaflets alternate or 

 subopposite ; flowers in terminal ramose compound-cymiferous 

 racemes. {Tropical eastern and southern Asia^ Indian Archipelago^ 

 tropical Australia, trofical western Africa.) See p. 359. 



46 ? Chytranthus Hook, f.^ — Flowers hermaphrodite or poly- 

 gamo-dioecious (nearly of Paneovia) ; calyx urceolate or shortly 

 tubulose; lobes obliquely inserted unequal, slightly imbricate at 

 margin. Petals 4, 5, unequal narrow, at base linear-attenuate 

 obconico-concave ; cavity furnished with a subulate slightly exserted 

 process. Stamens 8, 9, interior to irregular disk. Germen and 

 ovules of Paneovia; style incurved at apex 8 -fid; lobes subulate 

 stigmatose within more or less coadunate and tortuous. Capsule 

 wide, 3-lobed nearly to axis ; lobes more or less compressed ; cells 

 pilose within (tardily 2-valvate ?). Seeds nearly of Paneovia ; 

 cotyledons of exalbuminous embryo conferruminate ; radicle short 

 inferior. — Small trees ; leaves alternate pinnate ; flowers ^ in fascicu- 

 late racemes oftener springing from the wood tomentose,^ simple or 

 sparingly ramose, alternately cymiferous ; pedicels braeteate.*
