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. '

Calyx 5-partite. Corolla with a distinct campanulate tube, and 
erect, spreading or reflexed lobes, often with 2 narrow ridges on 
their basal half, overlapping to the left and more or less twisted in 
bud. Corona of 5 free, entire, bifid or trifid lobes, inserted with 
the stamens and occasionally upon their filaments above the middle 
of the corolla-tube, or at its mouth, alternating with the corolla- 
lobes. Stamens inserted above the middle or at the mouth of the 
corolla-tube; filaments free; anthers adnate to the dilated part of 
the style at their base, connivent in a cone, and connate at their 
tips. Pollen granular ; pollen-carriers spathulate, Style shortly 
conical at the apex, not exceeding the anthers, Follicles often
