 from Chachapoya, though less puberulent.. It is, by dissection, 

 the same as Bang's no. 2090. 



Tassadia Sprucei sp. nov. 



(Only a short terminal portion of a flowering branchlet seen.) 

 Subglabrous, only the youngest portions of the slender stems mi- 

 nutely puberulent : petioles 5-8 mm. long ; blades 3.5 cm. or more 

 long, 1.5 cm. or more broad, ovate, the base rounded, the apex 

 abruptly short-acuminate, the obtuse point short-aristate, margin 

 thinly revolute, thick, coriaceous, midrib and 3 or 4 pairs of pri- 

 maries prominent underneath : racemes axillary, slender, nearly 1 

 dm. long, the peduncle U— % of the length : the flowers in sessile 



umbellules of 3-5, sub-pendulous on slender pedicels about 2 mm. 

 long: calyx 1.5 mm. broad, divided more than half way, the lobes 



purpl 



corolla very
