Allied to M. ramosissima, but distinct in the soft, spreading 

 pubescence, the leaf-venation, and the size of the flowers. Leaves 

 3'5-4-5 cm. x l'5-2 cm. ; petiole 6 mm. at most ; secondary 

 veins 6-9 pairs ; stijndes not more than 6*5 mm. Pedicels barely 

 1 cm. at most. Calyx-lohes, to 1*5 cm. long. Co?-o//a-tube about 

 3"5 cm. long, lobes 1*4 cm. x 6"5 mm. Ovary 6 mm. long.

An isolated species, with M. fusco-inlosa Baker, perhaps, as its 

 nearest ally, but with many obvious differences from this ; it is 

 especially remarkable for the solitary sessile flowers. 



Leaves 7-11*5 cm. x 3-5-4-8 cm., petiole barely 1 cm. at most, 

 stipules 8 mm.; secondary veins 8-11 pairs. Calyx-lohes 1'8 cm. 

 long. Corolla-inhe upwards of 4-5 cm. long; lobes 1'3 cm. x 7 mm. 

 Ovary 5-6 mm. deep.
