 variously enlarged.) 



Macfadyena simplicifolia. — Erect (12-15 ^t.), compressed 



branchlets dichotomous, articulations of petioles and pedicels

 anthesis closed at apex and base: corolla twice long-er, white, 

 tubulose-infundibuliform, throat \ in. wide, lobes roundish 

 (6-9 I.): oblong anther-cells divergent at base, staminode not 



present: disk cupular: stigma minutely lamellate: ovules 2 to
