sepals 4, decussate-imbricate ; the tsvo exterior minute ; the interior 

 much larger and widely concave. Petals 4, similar in pairs, lined 

 within by a thick petaloid cristate squamule appendiculate at apex. 

 Disk excentric dilated before the smaller petals into two large glands, 

 Stamens 8, excentric; filaments more or less 2-adelphous at base ; 

 anthers introrse. Germen (in male flower rudimentary) excentric, 

 3-lociilar; style stigmatose at apex 3-fid ; ovules solitary ascendent. 

 Capsule subglobose, externally rou<j;h with stiff subulate spines, 

 septicidally 3-valvate ; seed (large) arillate exalbiiminous.^ — Scan- 

 dent shrubs ; leaves alternate, 1-3-foliolate ; folioles entire cuspid 

 reticulate glabrous ; flowers in remotely cymiferous racemes. ( Tro- 

 pical South America.^) 



52. Valenzuelia Bert.'' — Flowers polygamous (nearly of Paul- 

 linia) slightly irregular; sepals 5, imbricate. Petals 5, or oftener 4, 

 unequal, imbricate, lined within by a more or less developed squa- 

 mule appendiculately 2-lobed or 2-fid at apex. Disk unequally 5- 

 lobed irregular, sometimes hence duplex. Stamens 5-10, often 8, 

 excentric ; filaments free erect ; anthers short, introrsely rimose. 

 Germen (in male flowers rudimentary) 3-lobed, 3-locular ; style stig- 

 matose at apex 3-dentate ; ovule in cells solitary ascen lent ; micro- 

 pyle extrorsely inferior. Fruit capsular coriaceous, 1 -3-lobed; cells 

 loculicidal, 1-spermous ; seed oxarillate ascendent; cotyledons of 

 exalbuminous curved embryo fleshy, unequally 2-plicate — Small 

 erect glabrous trees ; leaves opposite small entire, equal or at base 

 unequal, coriaceous, 3-nerved, pellucidly punctulate ; flowers axil- 

 lary or more rarely terminal cymose corymbiform. {Chilian Andes.*) 



53. Bridgesia Bert.^ — Flowers diœcious (nearly of Valemuelia) 

 irregular ; sepals 5, imbricate. Petals 4, longer, dissimilar in pairs, 

 imbricate, furnished within with a large scale, incrassate-cristate at 

 apex. Disk ii-regular, unequally 5-lobed. Stamens 8, interior to
