j^ONIUM. Botanical Register, \84\. fol. 61. 



M. Toungianum ; caule fruticoso crasso, foliis subcartilagineis crassis lucidis 

 saturate viridibus obcordato-spathulatis basi subtetragoiiis apice obsolete 

 mucronatis margine attenuatis breviter ciliatis. Webb Histoire Natu- 

 relle des isles Canaries, Vol. III. p. 197. 



This plant, hitherto only known from the brief Latin phrase 

 above quoted, flowered in June, 1843, in the nursery of Mr. 

 Wm. Young of Milford, near Godalming, after whom it was 

 named by Mr. Barker Webb, who discovered it in the 

 Canaries. 



It appears nearly allied to ionium (Sempervirum) arbo- 

 reum, which, according to Mr. Webb, does not grow in the 

 Canaries ; but we have no information concerning it.
