The following specimens of large foliage appear to belong to 

 this genus, and perhaps to this species : —

 at the apex, 7-nerved and deeply cordate at the base, 17 in. long by 16 

 in. broad, puberulous along the veins ; tertiary veins arching ; petioles 

 12 to 18 in. long, with large glands at the extremity. In the interior 

 mountainous wooded parts of the district, for example, at Bembe, 

 about 130 miles from Ambriz, ^vhence the leaves and a fragment of 

 the stem were received by Welwitsch, having been sent by his friend 

 Monteiro. The sap of the stem and petioles is watery and somewhat 

 viscid. No. 451. Leaves without their petioles (one leaf only preserved)
