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

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

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

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

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

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

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

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

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

 mule appendieulately 2-lobed or 2-fld at apex. Disk unequally 5- 

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

 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.*)
