With a little of the aspect of my Desertan H. laciniosa, this is 

 a close ally and kind of modified or toned-down representative 

 of H. Despreauxii, D'Orb., from which, however, it is abundantly 

 distinct in its altogether feebler, less marked or elegant sculp- 

 tm-e, less prominent keels, coarse oblique ribs on the upper, 

 and regular equidistant ring-like plaits on the lower side, 

 larger open perforation, distinct brown narrow band beneath, 

 and generally much more depressed shape. 



Named after the yacht ' Miranda,' belonging to John Gray,Esq., 

 with whom and Mr.Wollaston I enjoyed the opportunity of two 

 or three days' botanizing in Gomera.

I know no species with which this can be confounded. It is 

 a highly curious and interesting addition to the very peculiar 

 and striking though small and restricted group of H. Gualtie- 

 rana, L., Wollastoni, Lowe, fcnhriuscula, Dcvsh., &c.
