The description of the male plant suggests a close affinity to T, minus, and only 

 a drawing of the type specimen at Stockhohn has been seen. The solitary fl* 'wers, 

 verrucnlose stem and bracts and bracteoles with ciliated margins suggest that the 

 species should be retained. 



III. OSYRIDICARPOS, A.DC. 



Flowers hermaphrodite. PeriantJi adnate to the ovary and pro- 

 duced above into a cylindrical tube ; segments 5, valvate, with a 

 tuft of hairs on the face attached to the back of the anther. 

 Stamens 5, inserted below the segments; fdaments short, slender ; 

 anthers ovoid, with 2 parallel cells dehiscing longitudinally ; disc 

 indistinct. Ovary inferior; ovules 2-3, pendulous from the tip of 

 a flexuous filiform central placenta ; stigma obscurely lobed. Drupe 

 globose, crowned with the persistent perianth. 



Undershruba, with long slender sarmentose sulcate branchlets ; leavres alternate, 

 shortly petioled, oblong or lanceolate, triplinerved ; flowers in terminal racemes 

 produced down into the axils of the leaves, small, green ; bracteoles minute.
