This species is of critical interest, as it connects the J/. Lygistum- 

 group, via M. Lohhii, with M. Ji mhriata and its allies. Spruce says 

 of his ])lant, that it is " herba alte volubilis, foliis carnosis. Corolla 

 intus lilacina, extus purpurea, basi virescens." The distinctive 

 characters are, the completely glabrous character of the mature vegeta- 

 tive parts, the rather pronounced leaf- stalks, and the short corolla 

 with lobes densely pubescent on the ventral side. Leaves 4 X 1'7 cm. 

 to 6*5 X 2*5 cm., with, petiole increasing to as much as, or more than, 

 1*5 cm. in length; the sheath of the stipules is about 2 mm. deep, 

 with the apiculate portion about the same in length. Peduncle 

 1 to 2 cm. long. Cali/x-lohQs 2*5 mm. x 1*7 mm., the latter being 

 the breadth when flattened out. (7oroZZ«-tube 4*5 mm. long, 2 mm. 

 wide at the mouth ; lobes 3 mm. long.

According to the author, this is allied to 31. Lygistum through 

 his M. Beyrichiana., being distinct especially in the general presence 

 of a puberulous feri-uginous indumentum, which covers even the 

 exterior of the corolla.
