;il. Quillaja >roL. — Flowers dioecious or polygamous. Eeceptacle 

 ut* hermaphrodite llower subconcave broadly cupuliform, lined by 

 a thick fleshy stellate disk produced into 5 alternipetalous lobes, 

 einarginate or 2-deiitate, much adnata to sepals. Sej^als 5, thick ; 

 pni'lloration valvate. Stamens 10, 5 larger alternipetalous inserted 

 ill apices of lobes of disk, 5 smaller between them ; filaments free 

 subulate ; anthers introrse dehiscing by two clefts. Carpels 5, 

 alternij)etalous inserted on slightly prominent bottom of receptacle 

 and cohering into a spuriously 5-celled ovary ; styles 5, free ter- 

 minal, at a])ex slightly dilated stigmatiferous ; ovules go, ventral 

 2-seriate densely imbricated. Fruit of 5 stellately sj)reading 

 legumes dehiscing in 2 longitudinal valves. Seeds oo , compressed 

 imiiricated ascending with a long superior wing; embryo exal- 

 buminous ; cotyledons convolute ; radicle inferior. — Evergreen trees ; 

 leaves alternate simple ; stipules 2, lateral deciduous ; flowers in 

 a.xillary or terminal cymes ; central flower of each usually her- 

 maphrodite. {Chili, Peru, Soufli Brazil.) See p. 383. 



32. Kageneckia E,. Sz Pav. — Flowers monoecious or dioecious; 

 receptacle lined by a thin disk. Imbricate calyx and corolla of

 sterile in female flower. Carpels 5 ; ovaries inserted on slightly 

 prominent bottom of receptacle ; ovules go (of Qiiillaja) ; styles 

 ventral, inserted at a variable height, at apex obliquely dilated 2-fid 

 stignuitiferous. Fruit of 5 stellately-spreading reflexed gibbous 

 slipper-shaped follicles. Seeds oo , imbricated ascending winged (of 

 Qiiillaja). — Evergreen trees ; leaves alternate coriaceous simple petio- 

 late; stipules caducous; flowers terminal or axillary racemose or corym- 

 bose, females cymoso-racemose or solitary. {Chili, Peru.) See p. 385. 



33. Vauquelinia Cork. — Flowers hermaphrodite ; receptacle 

 licmispherical, lined by a glandular disk. Sepals 5, valvate, and 

 petals 5, imbricate of Quill aja. Carpels 5, alternipetalous ; 

 ovaries connate below into a 5-celled ovary ; styles 5, at apex capi- 

 tellate stigmatiferous ; ovules 2, subbasilar collaterally ascending; 

 micropyle inferior extrorse. Carpels girded by persistent base of 

 rec«'])tacle and by calyx, finally coming apart ; dehiscence loculicidiil,
