The CALS Raster file format is a standard for the interchange of graphics data. It was developed by the United States Department of Defense (DoD) as part of the Continuous Acquisition and Life-cycle Support (CALS) initiative. It defines a standard storing raster (bit-mapped) image data, either uncompressed or compressed using CCITT Group 4 compression.

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.
