I have not seen this species. There is a good unpublished 

 coloured drawing of it at Kev;, made in 1823 from a plant received 

 that year from Salm Dyck himself, from which Fig. 219 was adapted.

 The above description is compiled and Fig, 220 adapted from 

 Salm Dycks figure above auoted as L have not seen any plant like it, 

 for it is ouite distinct from the plant Haworth called M. engustum 

 var, heterophyllum (see 16, 0. longum var. hamatum), differing 

 conspicuously by its less hooked leaves, from V7hich the elevated 

 ride-e along the lov.-er margin of the larger leaf of a pair is appar- 

 ently entirely absent, and by the sessile flov/ers.
