41 NATURAL HISTORY OF PLANTS. 



14. Castratella Naud.^ — Flowers (nearly of Lithohiumf) 4- 

 merous; receptacle ovoid. Sepals 4, short obtuse, persistent. 

 Petals 4, contorted, 1-setiferous at apex. Stamens 8, sub-equal ; 

 anthers oblong, attenuate at base, connective shortly produced at 

 base, not or very slightly appendiculate. Germen free beyond middle, 

 4-celled. Capsule 4-valved ; seeds subovoid glabrous. — A villose 

 hispid herb ; leaves all radicle rosulate, subsessile entire, 5-7-nerved ; 

 flowers ^ cymose at top of scape, often few ; pedicels 2-bracteolate ^ 

 under flower. (Columbia.'^) 



15. Eriocnema Naud.^ — Flowers (nearly of Castratella) 4-5- 

 merous ; receptacle subcampanulate villose. Sepals 4-5, broad, 

 3-angular, dorsally 1-dentate. Petals 4-5, acute, contorted. Stamens 

 8-10 ; filaments incurved above ; anthers linear basifixed, 1 -porous, 

 connective not produced nor appendiculate. Germen free, 3-celled. 

 Capsule 3-celled, 3-valved to base ; seeds straight or curved. — A 

 perennial hirsute herb ; rhizome thick ; leaves radicle petiolate 

 cordate, 3-9-nerved; flowers^ cymose at top of scape, spuriously 

 corymbose ; pedicels bracteolate ^ at base. (South. Brazil.^) 



16. Bertolonia Kadd.^ — Flowers 5-merous;^« receptacle cam- 

 panulate more or less turbinate or tubular, externally glabrous, sulcate 

 or costate, sometimes 3-9-alate.^^ Sepals 5, entire, serrate, or cihate; 

 sometimes (Diplarpea^^) with as many small teeth interposed. Petals 

 5, ovate, obovate or oblong, much contorted. Stamens 10, 2-seriate, 

 subequal; anthers various in form, often linear-subulate, 1, 2-porous 

 at apex, or spuriously rimose (Diolena ^^) from the pore running 

 downwards; connective not or scarcely produced at base, spurred 

 posteriorly downward, and furnished with an ascending appendage
