Masatierra: Portezuelo de Villagra (BERTERO no. 1601 !), on the north- 

 east precipice of Co Piramide, rock ledge, c. 625 m (fl.-fr. 3 /i2 [6, no. 3). Most 

 likely the plants observed on the face of Co Damajuana, c. 530 m, and at the 

 hack of O. de la Choza, c. 450 m, in both places quite out of reach, belonged 

 to this species.

only differ in the leaves. BERTERO's specimens were sterile, but another 

 collector, not quoted until now, found the inflorescence (in fruit). A specimen 

 in Herb. Kew labelled »Rea longifolia Phil., Reed oct. i872», consists of a leaf 

 of D. micrantha and a piece of an old inflorescence of D. marginata. 



The leaves are coriaceous, broad ovate with rounded or acuminate tip and 

 cordate base. They are quite entire, but the edge shows scattered warts, 

 visible on the leaf near the rock in plate 18. The petiole is broadly alate. 

 The upper leaves are sessile as in the former. The (hitherto undescribed)
