 matiferous at apex ; ovules 2, collaterally inserted on j^osterior 

 placentas, ascendent, incompletely anatropous ; micropyle extrorse 

 inferior. Fruit coriaceous, indéhiscent, inwardly aduate to receptacle, 

 persistent and crowned with accrescent unequal wing-shaped sub- 

 falcate coriaceous venose sepals. Seeds 1, 2 linear ; embryo exal- 

 buminous ; cotyledons elongate-narrow semicylindiical ; radicle

III. TEIGONIA. 



6. Trigonia Aubl. — Flowers hermaphrodite irregular ; receptacle 

 oblique, sub-plane or rather concave at apex. Sepals 5, unequal, 

 imbricated. Petals 5, alternate, imbricate, of which 2 are concave 

 or cucullate, sometimes gibbous, or 1 -laterally incrassate ; 2 are 

 ascendent membranous ; the fifth saccate or galeate at base 

 (lateral to the flower). Stamens 4-12, slightly perigynous ; 

 filaments connate at base in a short tiibe afterwards cut, from 

 fissure, either antherless, small or shorter than the other fertile one ; 

 anthers introrse, 2-rimose. Germen fi-ee, oblique, 3-locular (extremely 

 hirsute) ; style slender, truncate stigmatiferous at apex, sometimes 

 oblique or cupular ; ovules in cells co , descendent. Capsule 

 oagonal, 3-locular, septicidal ; valves septiferous at middle and 

 solute from columella, the cartilaginous eudocarp often separating there 

 from the exocarp. Seeds co , involute in gossypinous wool ; albumen
