Phaseolus dumosus, the year bean or year-long bean,[1][2] is an annual to perennial herbaceous vine in the family Fabaceae (legumes), native to a narrow region in the highlands of Guatemala.[2][3] It is one of the five Phaseolus domesticates and is similarly used for its beans.[1] It was recently found to be a hybrid between two other cultivated species of Central America, Phaseolus coccineus and P. vulgaris and displays intermediate characteristics.[2] Taxonomically, it was previously categorized as Phaseolus polyanthus and P. coccineus ssp. darwinianus.[4]
This species grows in humid forests and may reach 10 meters in length. It is visited by carpenter bees.[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.
