I regard this as the passage-form connecting the Lyyisium group 

 with M. mitis, M.fimhriata, and their allies. The present species is 

 distinct especially in the small rotund calyx-lobes, at most 2-3 x 

 1"7 mm. Leaves 4-7 cm. X l'5-2'3 cm. ; petiole 4-7 mm.

I was inclined at first to identify with this species a plant collected 

 by Pearce, in agreement with Sprague's MS. in the KeAV herbarium. 

 But comparison with the description, and with the figure quoted 

 above, leave no doubt that this plant is distinct. According to the 

 authoris, 31. vmhellaia is a native of woods in the neighbourhood of 

 Mufia, in Peru, fiowering in the late autumn. It has ovate, sub- 

 cordate leaves : the bracts form a distinct involucre to the umbellate 

 infiorescence, which, according to the figure, has a decidedly stout 

 peduncle and primary branches ; tlie cY//y.r-lobes are lanceolate ; and 

 the corolla-tuhe cylindrical, not widened at all toward the apex. 

 These characters distinguish M. umhellata witbout doubt from 

 Pearce's plant, which 1 proceed to describe as a new si^^'cies, viz.,
