Notes
Although very similar to E. virgatum, E. Meyer, this plant essentially differs by its larger flowers, and especially in its leaves, which are at least twice as thick as those of E. virgatum, and, in the adult state, are densely covered with minute irregular pits, which appear, when viewed under a lens, as if placed between a very dense network of veins. I find no trace of such structure in the leaves of E. virgatum.
