The affinity is undoubtedly with M. Lyyistiivi. The present 

 species is at once recognizable by the small, flat, herbaceous leaves, 

 with average size not much more than 2 cm. x 7 mm. The stipules 

 form a rather deep sheath, relatively speaking, with a very short 

 apiculate portion. The calyx, together with the ovary, is barely 

 2 mm. in the flower, the small lobes barely half a millimetre. Corolla- 

 tube 5 mm. long, and about 2 mm. wide at the mouth ; lobes about 

 2'5 mm. long and 1'5 mm. broad. Capsule 3 mm. long, 2 mm. wide.

Allied to M. Lygisium and its circle of affinity by wa}^ of 

 M. evenia and M. Triance, this species is distinct in the leaf- 

 characters, the truncate stipules, and the glabrous ovary and calyx. 

 Leaves 3-5 cm. X l-3-2"3 cm., with peiiole 3-7 mm. long. Primary 

 peduncle as much as 1'5 cm., or even longer. 6V/_;/.r-lobes barely 

 2 mm. Corolla-\\A)ii 7 mm. long, 3*5 mm. wide at .the mouth, the 

 liml) 6-7 mm. in diameter.
