5-merous ; receptacle minute very shortly cupular. Sepals 5, 

 lanceolate. Corolla urceolate or subrotate, tube short sometimes 

 ventricose, sometimes slightly contracted above ; lobes of Hmb 5, 

 short, valvate. Stamens 5, small, enclosed in tube ; filaments short ; 

 anthers ovately cordate. Germen adnate to receptacular cupule only 

 at base or to middle, remainder free, rather broad to apex, 2-celled ; 

 branches of short style 2, capitellate at stigmatose apex, finally open 

 or recurved. Placentas and ovules go (oi Oldenlandia). Fruit cap- 

 sular almost entirely free, compressed contrary to septum, obcordate 

 or at apex truncate or broadly 2-lobed or sub-2-dymous ; cells 2, 

 divergent at apex and dehiscing inwards at margin. Seeds small, 

 globose, ovoid or compressed, tuberculate- or papillose-rugose ; 

 albumen fleshy ; cotyledons of linear embryo small. Other characters 

 of Oldenlandia. — Annual or perennial herbs, erect or creeping at base ; 

 leaves opposite membranous ; petioles dilated at base to a membrane 

 connate with obtuse or little prominent stipules ; flowers in terminal 

 cymes;' cymes 2-parous or 1 -parous above; flowers sessile or shortly 

 pedicellate, 1. -lateral.^ {Warm America, Asia and Oceania.^) 



134 ? Polypremum L.* — Flowers (nearly of Oldenlandia or Mitre- 

 ola) 5-merous or often 4-merous; receptacle shortly cupular. Sepals

 equal to, calyx or shorter tubular subcampanulate ; throat slightly 

 villose or subglabrous ; lobes short obtuse, imbricate. Stamens 4, or 

 more rarely 5, inserted in tube of corolla enclosed ; filaments short ; 

 anthers ovate dorsifixed introrse, 2-rimose. Germen adnate to 

 receptacle at base, above in great part free, 2-celled ; style short, at 

 apex stigmatose obtuse entire or very shortly 2-lobed. Ovules oo, 

 inserted on an ascending placenta affixed to base of septum. Fruit 

 capsular, slightly compressed contrary to septum, finally loculicidal 

 generally septicidal ; seeds oo, subglobose smooth albuminous; embryo
