Tuberculoid leprosy is a form of leprosy characterized by solitary skin lesions that are asymmetrically distributed with few lesions and well demarcated edges. There is also early and marked nerve damage. It tends to heal spontaneously.[1]: 345 Tuberculoid leprosy is characterized by the formation of epithelioid cell granulomas consisting of a large number of epithelioid cells. In this form of leprosy, Mycobacterium leprae are either absent from the lesion or occur in very small numbers. This type of leprosy is the most benign and the least contagious.[2][3]

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.
