Davey 14426 and Horwood 11 appear to be only very stunted plants of this species, with stems 2.5-5 cm h., rising from short thick irregularly brchd., woody prostrate brchs., but they require to be compared when alive, no other distinction being apparent in the dried material. This plant bears a great semblance to that figured by Salm Dyck as M. semidentatum, but I consider best to give it a distinct name for the present. The name M. semidentatum appeared in Salm Dyck's catalogues as a mere nomen nudum; he sent a species under that name to Haworth and also to Kew; Haworth described it as having only one tooth on the back of the lvs. There are at Kew two original drawings of the species sent by Salm Dyck under that name which agree with Haworth's description in having only one tooth on the back of the lvs., these are also described as more erect and more crowded, and the fls. as being smaller with more numerous and obtuse (not acum.) pet. than those in the figure which Salm Dyck gives of his plant.
