Tbe leaves are 4 in. long by scarcely 2 in. broad, and have an 

 entire obtuse base ; the petioles | in. long. The whole inflorescence 

 is only h-\ in. in length, the peduncles being 3-4 lines, and the 

 closely crowded pedicels borne on its short branches, 1-1-| lines. 

 The calyx-segments are f-1 line long ; the corolla is 2 lines long, 

 its lobes only f line ; the mouth of the tube is filled with a ring of 

 stiffish hairs, while the interior of the tube at the level of the 

 stamens bears tufts of downwardly pointing shorter but otherwise 

 similar hairs. The corona-scales, except for the short (less than 

 ^ line) acute tip, are adnate to the backs of the anthers, the broader 

 triangular appendage of which overtops them ; the stamens are 

 1 line long, with coherent filaments. 



Is near the Indo-lVIalayan and Chinese species M. tinetona Br., 

 but is distinguished by its inflorescence, larger flowers, and leaves 

 with a marked obtusely pointed base.
