Callicarpa ampla, also called the capa rose, is a species of plant in the family Lamiaceae. It is found in Puerto Rico in the Caribbean region. It is threatened by habitat loss and is a critically endangered plant species.
The capa rose was first collected in Puerto Rico by Heinrich Wydler in 1827. However, it was not until Schaur in 1847 that this plant was identified as the capa rose. Since that time, there have been only seven individuals collected, all but one from Puerto Rico. The exception was collected from St. Thomas in the Virgin Islands by Riedle, but none have been discovered there since. It is questionable whether the species is extirpated from the area, or whether it existed there at all. [2] Once spread through Puerto Rico, it is now only located in the Luquillo Mountains, specifically the palo Colorado forest region. [3]
The kingdom indicated this species is a plant. The subkingdom implies that this species is a vascular plant: It has a system of tissues (roots, leaves, and stems) allowing food and water to travel. [4] The superdivision is the classification for seed plants, and the division categorizes the capa rose as a flowering plant. The class indicates the species to be a dicotyledon. The embryo inside each seed produces leaves, or cotyledons, when germinated. This species produces two leaves, thus dicotyledon. [5] The most common characteristic of the subclass of this species is the tight cluster of individual flowers, showing the appearance of one larger flower. [6] The order indicates that the capa rose has opposite, or pairs of symmetrical, leaves. [7] The family is almost all tropical plants with clustered flowers, most native to the western hemisphere. [8] The genus classifies this flower as a beautyberry. [7]
Capa rose is considered a small evergreen tree or shrub. It can grow up to 15 metres (49 ft) tall. When twigs are young, they are whitish color. [2] The branches are tetragonal, meaning four-sided. The leaves are broad at the middle and taper to the end, somewhat of an elliptical shape that is 8–35 centimetres (3.1–13.8 in) long and 3.5–8 centimetres (1.4–3.1 in) wide. The leaves are a dark green on top and a lighter green beneath. The veins are raised on the bottom with whitish scurfy, and the top is smoother and shiny. The flowers are actinomorphic, or star-shaped. The petals are white and approximately 1.7 millimetres (0.067 in) wide by 1.8 millimetres (0.071 in) long. It is also hermaphroditic, having both male stamens and female pistils and ovary. There are four 5.2 millimetres (0.20 in) long stamens and one 1 millimetre (0.039 in) wide ovary. The berries produced are about 6 millimetres (0.24 in) in diameter and contain four seeds. Ripened seeds are purple, and immature seeds are white. [3]
Presently, the capa rose only exists in Puerto Rico, specifically within the Caribbean National Forest. That forest is divided into several regions of plants, and the capa rose is located in the Palo Colorado region. There were two sites reported in the Rio Blanco district of the Nauguabo municipality. Only one site was discovered in the Mameyes II district, and two sites were in the Jimenez district, both of the Rio Grande municipality. [3]
The Luquillo Mountains are about 15 kilometres (9.3 mi) from the nearest shore. The mountains’ highest elevation above sea level is over 1,000 metres (3,300 ft), with precipitation increasing at higher elevations. [9] The palo Colorado region makes up about 17 percent of the national forest. It occurs at elevations higher than 600 metres (2,000 ft). [3] The average annual precipitation for the palo Colorado region is from 300 to 450 centimetres (120 to 180 in). However, the off-season for rainfall is from February to April. The humidity ranges from 90 to 100 percent. The mean temperature in this region is about 21 °C (70 °F). The capa rose grows on the slopes of the mountains, which protects it from severe wind. However, hurricanes do occur in that area from time to time. [3]
Not only is the species extremely localized, found in only one section of one country, it is also on an island. This isolation alone causes the species to be at high risk for extinction. However, the capa rose is also facing habitat loss. Its habitat is being lost to deforestation and agriculture (World Conservation Union, 2007). Because Puerto Rico is considered United States territory, the forest habitat for the rose is managed by the USDA Forest Service. Forest management such as trails, cutting, agriculture and shelter construction all endanger the plant further. [3] There are other factors affecting the rapid decline of the plant. There is a very low number of plants in Puerto Rico. The loss of just one plant greatly endangers its survival. The risk of the plant being collected due to its rarity and ornamental value is yet another threat, and for this reason the Forest Service did not list its habitat as critical. This would publish detailed information about the location of the plants, and possibly increase the instances of collection (Fish and Wildlife Service, 1992). The location of the capa rose also suffers a lot of damage due to hurricanes. These hurricanes wipe out existing plants and damage locations for future seedlings to develop. [3] They are also poor reproducers and dispersers, so the protection of the individuals and habitat are all the more crucial (World Conservation Union, 2007).
The capa rose was listed as endangered in 1992. [10] The recovery plan was implemented in 1995. It outlines what actions should be taken to protect the plant from further loss and increase its population. A management plan required steps to protect the plant and its habitat.
Puerto Rico, officially the Commonwealth of Puerto Rico, is an archipelagic island U.S. territory comprised of the eponymous main island of Puerto Rico and 142 smaller islands, including Vieques, Culebra, and Mona. It is located between the Greater and Lesser Antilles in the northeastern Caribbean Sea, east of Hispaniola, west of Saint Thomas, north of Venezuela, and south of the Puerto Rico Trench. Measuring 177 km in length and 65 km in width with a land area of 8,868 sq km, the main island is the 3rd largest in the U.S., 4th in the Caribbean, 29th in the Americas, and 81st in the world, making it the 174th largest country or dependency by surface area. With 3.2 million residents, it is the 2nd largest in the U.S., 4th in the Caribbean, 4th in the Americas, and 31st in the world, making it the 136th largest country or dependency by population.
El Yunque National Forest, formerly known as the Caribbean National Forest, is a forest located in northeastern Puerto Rico. While there are both temperate and tropical rainforests in other states and territories, it is the only tropical rainforest in the United States National Forest System and the United States Forest Service. El Yunque National Forest is located on the slopes of the Sierra de Luquillo mountains, encompassing more than 28,000 acres of land, making it the largest block of public land in Puerto Rico.
The Puerto Rican amazon, also known as the Puerto Rican parrot or iguaca (Taíno), is the only extant parrot endemic to the archipelago of Puerto Rico, and belongs to the Neotropical genus Amazona. Measuring 28–30 cm (11.0–11.8 in), the bird is a predominantly green parrot with a red forehead and white rings around the eyes. Its closest relatives are believed to be the Cuban amazon and the Hispaniolan amazon.
The elfin woods warbler is a species of bird endemic to Puerto Rico, where it is local and uncommon. Discovered in 1968 and described in 1972, it is the most recently described New World warbler.
The Guánica State Forest, popularly known as the Guánica Dry Forest is a subtropical dry forest located in southwest Puerto Rico. The area was designated as a forest reserve in 1919 and a United Nations Biosphere Reserve in 1981. It is considered the best preserved subtropical dry forest and the best example of dry forest in the Caribbean.
Eleutherodactylus portoricensis is a frog native to Puerto Rico that belongs to the family Eleutherodactylidae. Its vernacular English names are forest coquí,upland coquí, mountain coquí, and Puerto Rican robber frog. The species’ range spans the Luquillo Mountains of northeastern Puerto Rico and the Cordillera Central, which forms the highland “backbone” of Puerto Rico and includes an eastern extension beginning at the city of Cayey. However, the species is likely extirpated from the western Cordillera Central.
Banara vanderbiltii is a rare species of plant in the willow family known by the common name Palo de Ramón. It is originates from Puerto Rico in the hills of Rio Lajas, and the east peak of "Tetas de Cayey" mountains in Salinas, where there are fewer than 20 known individuals left in the wild. At the time it was listed as an endangered species of the United States in 1987, there were only six plants remaining.
Buxus vahlii, or Vahl's boxwood, is a rare species of plant in the boxwood family. It is native to Puerto Rico and St. Croix in the U.S. Virgin Islands, where it is known from no more than four populations in total. It has probably never been very common, but its distribution has been reduced by deforestation and other human disturbance of its habitat. At the time it was listed as an endangered species of the United States in 1985, it was thought to be endemic to Puerto Rico. Reports that it existed in Jamaica have not been confirmed. A few individuals have been located in St. Croix, some of which are within Sandy Point National Wildlife Refuge.
Eugenia haematocarpa is a rare species of plant in the family Myrtaceae. It is endemic to Puerto Rico.

El Toro Wilderness is a 10,254-acre (41.5 km2) federally designated National Wilderness Preservation System unit located within El Yunque National Forest on the Sierra de Luquillo in eastern Puerto Rico. El Toro, named after the highest peak in the forest at 3,524 feet (1,074 m), is the only tropical wilderness in the United States National Forest System. It was created in 2005 by the Caribbean National Forest Act of 2005.
Cornutia obovata is a rare species of tree in the mint family, and formerly considered a member of the verbena family. It is endemic to forested slopes in Puerto Rico, where its common names are capá jigüerilla, nigua, and palo de nigua. When it was added to the endangered species list of the United States in 1988 there were only seven individuals known to remain in the wild. By 1998 there were eight plants known. This is considered one population divided amongst a few locations in the mountain forests of the island.
Lepanthes eltoroensis is a species of orchid known by the common name Luquillo Mountain babyboot orchid. It is endemic to El Yunque National Forest in Puerto Rico, growing primarily in the Luquillo Mountains. It is named for the El Toro Trail in the mountains. It was a federally listed endangered species of the United States from 1991 to 2021, when it was delisted due to recovery.
Ottoschulzia rhodoxylon is a rare species of tree in the family Icacinaceae known by the common name pincho palo de rosa. It is native to Puerto Rico and Hispaniola.
