Cyathea × fagildei is a tree fern endemic to the Sierra de Moa and Sierra del Purial in Guantánamo Province, Cuba. It is a natural interspecific hybrid between Cyathea minor and Cyathea woodwardioides . The spores of C. × fagildei are normal in appearance; Caluff and Serrano (2002) suggest that it might therefore be fertile.

The order Cyatheales, which includes the tree ferns, is a taxonomic division of the fern class, Polypodiopsida. No clear morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyletic. Some species in the Cyatheales have tree-like growth forms, but others have rhizomes.

Guantánamo is the easternmost province of Cuba. Its capital is also called Guantánamo. Other towns include Baracoa. The province has the only land border of the important U.S. Navy base at Guantánamo Bay.

Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, Gulf of Mexico and Atlantic Ocean meet. It is east of the Yucatán Peninsula (Mexico), south of both the U.S. state of Florida and the Bahamas, west of Haiti and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The area of the Republic of Cuba is 110,860 square kilometres (42,800 sq mi). The island of Cuba is the largest island in Cuba and in the Caribbean, with an area of 105,006 square kilometres (40,543 sq mi), and the second-most populous after Hispaniola, with over 11 million inhabitants.

The type material was collected in the headwaters of Río Toa, reserve of Cupeyal del Norte, Guantánamo Province at an altitude of 500 m on August 27, 1986.

Holotype single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described

A holotype is a single physical example of an organism, known to have been used when the species was formally described. It is either the single such physical example or one of several such, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN the definitions of types are similar in intent but not identical in terminology or underlying concept.

Guantanamo Bay Naval Base military base of the United States Navy

Guantanamo Bay Naval Base, officially known as Naval Station Guantanamo Bay or NSGB, is a United States military base and detention camp located on 120 square kilometers (45 sq mi) of land and water at Guantánamo Bay, Cuba, which the U.S. leased for use as a coaling station and naval base in 1903. The lease was $2,000 in gold per year until 1934, when the payment was set to match the value in gold in dollars; in 1974, the yearly lease was set to $4,085. The base is on the shore of Guantánamo Bay at the southeastern end of Cuba. It is the oldest overseas U.S. Naval Base. Since the Cuban Revolution of 1959, the Cuban government has consistently protested against the U.S. presence on Cuban soil and called it illegal under international law, alleging that the base was imposed on Cuba by force.

Cuba is an island nation in the Caribbean Sea. Cuba has an official area of 109,884 km² (42,426 sq mi). Its area is 110,860 km² (42,800 sq mi) including coastal and territorial waters. The main island (Cuba) has 5,746 km (3,570 mi) of coastline and 28.5 km (17.7 mi) of land borders—all figures including the United States territory at Guantánamo Bay, where the U.S. Navy's Guantanamo Bay Naval Base is located.

Administratively, Cuba is divided into 15 provinces and a special municipality that's not included in any province. The last modification was approved in August 2010, splitting Havana province into two new provinces: Artemisa and Mayabeque. The new provinces started functioning from January 1, 2011. Havana City Province recovered its original name: La Habana.

Sierra Maestra is a mountain range that runs westward across the south of the old Oriente Province in southeast Cuba, rising abruptly from the coast. The Sierra Maestra itself is located mainly in Santiago de Cuba Province and in Granma Province. Some view it as a series of connecting ranges, which joins with others extending to the west. The Sierra Maestra is the highest area of Cuba. It is rich in minerals, especially copper, manganese, chromium, and iron. At 1,974 m (6,476 ft), Pico Turquino is the range's highest point.

Guantánamo Bay is a bay located in Guantánamo Province at the southeastern end of Cuba. It is the largest harbor on the south side of the island and it is surrounded by steep hills which create an enclave that is cut off from its immediate hinterland.

Cyathea × boytelii is a tree fern endemic to the Sierra Maestra range of southeastern Cuba. It is a natural interspecific hybrid between Cyathea balanocarpa and Cyathea woodwardioides. The spores of C. × boytelii are normal in appearance; Caluff and Serrano (2002) suggest that it might therefore be fertile. This theory is strengthened by the presence of a large population of C. × boytelii in the Gran Piedra area. Caluff and Serrano (2002) note that "a full range of intermediates linking this hybrid with its parent species suggests the occurrence of backcrossing".

The provinces of Cuba are divided into 168 municipalities or municipios. They were defined by Cuban Law Number 1304 of July 3, 1976 and reformed in 2010 with the abrogation of the municipality of Varadero and the creation of two new provinces: Artemisa and Mayabeque in place of former La Habana Province.
