The Puerta Bab al-Mardum, or Puerta de Valmardón, is a city gate of Toledo, Spain. It was built in the 10th century and is one of the oldest gates in the city. Its name 'mardum' is Arabic for 'blocked up'. Perhaps because its function was taken over by the Puerta del Sol. The Spanish name Valmardón is a rough, phonetic imitation of the Arabic. 'Mezquita Bab al-Mardum' is another name for the nearby Mosque of Cristo de la Luz.

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.
