- The leaves of most orchids are perennial, that is, they live for several years, while others, especially those with plicate leaves as in " Catasetum ", shed them annually and develop new leaves together with new pseudobulbs.
- Darwin described " the most remarkable of all Orchids ", " Catasetum ", and showed how in these flowers, " as throughout nature, pre-existing structures and capacities [ had been ] utilised for new purposes ".
- Since the species is widespread, " E . cordata " is known to pollinate the more widespread orchid species such as " Cycnoches ventricosum, Coryanthes macrantha, Coryanthes speciosa, Catasetum barbatum, Catasetum russellianum, and Catasetum maculatum ."

- This plant had astonished botanists in 1836 when Robert Hermann Schomburgk stated that he had seen one plant growing three distinct flowers which usually grew separately and had wrongly been categorised as three distinct genera, namely " Catasetum tridentatum ", " Monachanthus viridis ", and " Myanthus barbatus ".

- John Lindley had remarked that " such cases shake to the foundation all our ideas of the stability of genera and species . " One of Darwin's correspondents told of delight at growing a beautiful specimen of " Myanthus barbatus " imported from Demerara, then dismay when the plant flowered the next year as a simple " Catasetum ".
