Allium runyonii is a North American species of wild onion native to southern Texas about as far north as Corpus Christi, as well as to the Mexican States of Nuevo León and Tamaulipas. It is found on sandy soils including in plains along the Río Grande.[1][2]
Allium runyonii produces egg-shaped bulbs up to 2 cm long. Flowering stalks can reach a height of 50 cm. Flowers are urn-shaped, about 6 mm across; tepals white with pinkish midribs; anthers and pollen are yellow; ovary does not have a crest.[1][3][4][5]

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.
