 Sapria), or valvate (Brugmansia) ; anthers 1-seriate, adnate under the dilated top of 

 a staminal column (synema), and opening by a single or double pore. Ovary with 

 confluent or distinct many-ovuled placentas. Pericarp semi-adherent or free, 

 fleshy. Seeds recurved, funicle dilated at the top. Embryo albuminous, axile,

Tribe II. EYDNORB^. 



Flowers . Perianth 3-fid, sestivation valvate. Stamens inserted on the 

 perianth-tube; anthers numerous, dehiscence longitudinal, united into a 3-lobed 

 ring, of which each lobe is opposite to the perianth-segments. Ovary inferior; 

 stigma sessile, depressed, of 3 lobes formed by apposed lamellse, distinct to the cavity 

 of the ovary, where they become placentiferous ; placentas pendulous from the top 

 of the ovary, sub-cylindric or branching, everywhere covered by very numerous 

 orthotropous ovules. Fruit fleshy. Embryo globose in the axis of a cartilaginous 

 albumen. — Parasitic on the rhizomes o? Euphorbia in South Africa.
