I have sedulously compared this with specimens of L. ovata 

 gathered in company with Dr. Taylor at Cromaglown, one of his 

 original stations, and cannot detect the slightest difference. It is a 

 rather larger plant than L. hamatifolia. Hook., from which it differs 

 essentially as follows : the leaves are more lurid and opaque (more 

 chlorophyllose) and never serrated, as they are most frequently in the 

 other ; the larger lobe is oblique, trapezoideo-ovate, with the margins 

 convex nearly to the apex (while in the ovato-acuminate leaves of 

 L. hamatifolia the margins of the larger lobe are concave above the 

 junction with the involute lobe) ; the involute lobe is smaller, and 

 has not a projecting tooth near the apex as in Z. hamatifolia.
