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 isa 
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 L. hamatifolia.
