Although it appears that the name should be corrected from P. elizabethae to P. elizabethiae according to the IAPT code 60C.2, the name "Elizabetha" previously existed in Latin form, so no correction is required. Similar to P. falcifolia, but differing in the leaves which are ovate to ovate-lanceolate and with a long distinct petiole, 2-3X the length of the blade. See related: P. agleniana, P. falcifolia, P. obliqua and P. thearosa.
