A step (Latin: gradus, pl. gradūs) was a Roman unit of length equal to 2½ Roman feet (pedes) or ½ Roman pace (passus). Following its standardization under Agrippa, one step was roughly equivalent to 0.81 yards or 0.74 meters.
The Byzantine pace (Greek: βήμα, bḗma) was an adaption of the Roman step, a distance of 2½ Greek feet.[3]
Similarly, the US customary pace is a distance of 2½ feet or 30 inches (760 mm).

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
