Campyloneurum phyllitidis

Campyloneurum phyllitidis (Linnaeus) C.

Known as the long fern thong, it is a species of fern in the Polypodiaceae family. It is an epiphyte, which grows on other plants, in general, the fern is found more and more in the treetops, it grows in hammocks, either as an epiphyte or on rocks or stones. It has a relatively large rhizome from which many fine rootlets covered in dark reddish brown scales grow. Its leaves are simple in shape, hair, 45-100 centimeters (18-39 inches) long and 8-12 centimeters (3.1-4.7 inches) wide. Sori are round and small, occurring on both sides of the lateral leaf veins.

Tracking down the correct name of Campyloneurum phyllitidis which means very stately bird’s nest fern, took a little time and help. Botanists have determined the species over a dozen scientific names, but had no idea what genus or species name to start searching first. Since the fern is variable, and has more than one growth form alone, it has been misidentified by a large number of scientific names, most of which are now synonymous. And to make things a little worse, scientists have had some disagreement about the correct way to write the genus name.

Our model of Campyloneurum phyllitidis was a gift from a family who are dedicated to tour the world to collect different species of orchids, we were handed this and several beautiful specimens of orchids and ferns for their rareness and lack of knowledge of it.

Belonging to the genus “Campyloneuron” or “Campyloneurum”, this species is found in the Tropics leading to the discovery of this fern and has been given many different names by many different botanists. However, the species name is now accepted Phyllitidis Campyloneurum. The species is common to most of tropical America . Samples have been collected in Mexico , Central America , the Caribbean Islands , Colombia , Venezuela , the Guiana Shield , some parts of Brazil , Argentina , Ecuador , Cuba and Peru .

Campyloneurum phyllitidis is both a species of epiphitic fern (a plant that grows on another vegetable) and is found growing on tree branches, as well as epipetric which means that it is capable of growing on stone. Generally, the epipetric species grow on limestone. The species is often found in mountainous regions of the humid tropical rain forest. If you grow this species you will find that it prefers a humid environment and enjoys the water frequently. The sori (spores) grow in a very distinctive parallel pattern between the veins of the frond on the reverse of the frond.

It is found in Central and South America, from Mexico in the north of Peru , in the South and among them Panama , Bolivia , Brazil , Paraguay and the Antilles . It is also present in Florida, Puerto Rico, Hawaii and the Virgin Islands. Fern is common on Barro Colorado Island , Panama and is known to grow on Platypodium elegans, Ceiba pentandra, Tabebuia guayacán, Anacardium excelsum, Socratea exorrhiza, Marila laxiflora, and xanthochyma Perebea.

It has short creeping stems, 4 to 10 mm in diameter. Leave few upright many, arching. Petiole essentially absent up to approx. 9 cm. Leaf yellowish green, linear to linear-elliptic, 24 – 140 × 3 – 12 cm, leather, attenuated base, entire margins to slightly undulate, sharp apex (sometimes forked). Veins evident, primary veins prominent, straight or slightly curved, areolas in 7 – 16 (- 18) series between Costa and margin, with free veins included, a percurrent ventileos often dividing a few more areolas. Sori in several rows on each side of Costa. 2 n = 148.

Circumneutral sub-acid substrate ;; epiphytes in hammocks and swamps, sometimes on limestone sink walls where it is reduced in size by 0 m.


Campyloneurum phyllitidis can be cultivated, and is the most common species of Campyloneurum found in cultivation. The fern grows well in well-drained soils in the middle light levels. It has to be protected from slugs and snails, it was cultivated in the United Kingdom during the Victorian era, when ferns were very popular (the phenomenon known as Pteridomania). The fern was described by a writer of the time, Shirley Hibberd, as “very different,” and that it formed a “striking object when grown well.”



A family of terrestrial, rupicolous or epiphytic ferns, of a sub-cosmopolitan distribution, comprising about 50 genera and around 950 species included under 5 different groups. They have creeping, ascending, suberect, or erect rhizomes, with scales, and less frequently with hairs only. Monomorphic or semi-morphic leaves, fully dimorphic in only a few genera.

Simple or pinnate sheets, sometimes pedaled. Free or bifurcated nerviation, or anastomosed several times and very reticulated. Sporangia grouped into marginal or intramarginal sori, sometimes arranged along the nerves, without true indusium, and often protected by the reflex margin of the lamina. Globose or tetrahedral spores.
