The World Guide to Covered Bridges is published by the National Society for the Preservation of Covered Bridges (NSPCB).[1] It uses a covered bridge numbering system developed by John Diehl, the chairman of the Ohio Covered Bridge Committee. The committee first used the numbering system in 1953 to publish a list of covered bridges in Ohio.[2]
The National Society for the Preservation of Covered Bridges has produced eight editions of this book. The first edition was titled Guide to Covered Bridges of the United States. Later editions have all been titled World Guide to Covered Bridges.

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.
