This species is distinct in the four clearly-marked, almost trans- 

 lucent, raised angles on the stem, with their reflexed teeth, comparable 

 with the similar feature in many species of Galium. This is the sole 

 sucrgestion of a mechanical aid to climbing that I have observed in 

 Mcmettia, with the possible exception of the deflexed indumentum in 

 M. Glaziovii {infra, no. 61). The thin papery leaves ai-e fi-om 5 to 

 7 cm. long and I'S to 2 cm. wide, with petiole 2 to 8 mm. long ; stipule- 

 sheath 1 to 2 mm. deep, the apical ])urtion 1 mm. Ca7^.r-lobes 

 5 mm. or longer. Corolla 5 cm. long, 1 cm. Avide at the mouth. 

 Anthers 5 mm. long and nearly 2 mm. broad.
