Ticodendron incognitum is the only species of Ticodendron, and the only member of the family Ticodendraceae. It is most closely related to the family Betulaceae.

Contents

It was discovered only in 1989 in Costa Rica, having been overlooked previously due to its habitat in poorly researched cloud forests and its very 'ordinary' appearance; further research showed its range extends from southern Mexico (Veracruz, Oaxaca, Chiapas), south through Central America to Panama. [3] [4] [5] [6]

It is a tree, 20–30 m tall, superficially resembling an alder in appearance, with alternate, simple leaves 5–12 cm long with a serrated margin.

Fossil record

Ferrignocarpus bivalvis fossil fruits, from the Middle Eocene of Oregon and the Early Eocene London Clay flora of southern England, correspond closely in morphology and anatomy to fruits of extant Ticodendron. [7]

Fagales Order of flowering plants

The Fagales are an order of flowering plants, including some of the best-known trees. The order name is derived from genus Fagus, beeches. They belong among the rosid group of dicotyledons. The families and genera currently included are as follows:

Araceae Family of flowering plants

The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe or leaf-like bract. Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.

Tupelo

Tupelo, genus Nyssa, is a small genus of deciduous trees with alternate, simple leaves. It is sometimes included in the subfamily Nyssoideae of the dogwood family, Cornaceae, but is placed by other authorities in the family Nyssaceae. In the APG IV system, it is placed in Nyssaceae.

Geraniaceae Family of plants

Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus Geranium. The family includes both the genus Geranium and the garden plants called geraniums, which modern botany classifies as genus Pelargonium, along with other related genera.

Ulmaceae Family of flowering plants

The Ulmaceae are a family of flowering plant that includes the elms, and the zelkovas. Members of the family are widely distributed throughout the north temperate zone, and have a scattered distribution elsewhere except for Australasia.

Winteraceae

Winteraceae is a primitive family of tropical trees and shrubs including 60 to 90 species in five genera. It is of particular interest because it is such a primitive angiosperm family, distantly related to Magnoliaceae, though it has a much more southern distribution. Plants in this family grow mostly in the southern hemisphere, and have been found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropics, with most of the genera concentrated in Australasia and Malesia. Drimys is found in the Neotropical realm, from southern Mexico to the subarctic forests of southern South America. Takhtajania includes a single species, T. perrieri, endemic only to Madagascar.

Altingiaceae Family of flowering plants in the order Saxifragales

Altingiaceae is a small family of flowering plants in the order Saxifragales, consisting of wind-pollinated trees that produce hard, woody fruits containing numerous seeds. The fruits have been studied in considerable detail. They naturally occur in Central America, Mexico, eastern North America, the eastern Mediterranean, China, and tropical Asia. They are often cultivated as ornamentals and many produce valuable wood.

Myristicaceae

The Myristicaceae are a family of flowering plants native to Africa, Asia, Pacific islands, and the Americas and has been recognized by most taxonomists. It is sometimes called the "nutmeg family", after its most famous member, Myristica fragrans, the source of the spices nutmeg and mace. The best known genera are Myristica in Asia and Virola in the Neotropics.

<i>Haptanthus</i>

Haptanthus is a monotypic genus containing the sole species Haptanthus hazlettii, a shrub or small tree known only from the locality of Matarras in the Arizona Municipality in Honduras. Its flowers are unique among the flowering plants. A single "female" (carpellate) flower has two branches on either side which carry "male" (staminate) flowers. The flowers are very simple, lacking obvious sepals or petals. The family placement of the genus has been uncertain, but based on molecular phylogenetic research, it is included in the family Buxaceae as of September 2014. Very few individuals have ever been found and its habitat is threatened by logging.

<i>Restrepiella ophiocephala</i>

Restrepiella ophiocephala, commonly called the Snake's head restrepiella is an epiphytic orchid native to Mexico, Central America, Colombia, and Florida. The epithet ophiocephala is derived from the Greek words ὄφις, ophis (snake) and κεφαλή, kephalē (head).

<i>Eucommia</i>

Eucommia is a genus of small trees now native to China, with a fossil record that shows a much wider distribution. The single living species, Eucommia ulmoides, is near threatened in the wild, but is widely cultivated in China for its bark, and is highly valued in herbology such as traditional Chinese medicine.

<i>Uvularia perfoliata</i>

Uvularia perfoliata, the perfoliate bellwort, is a perennial forb native to the eastern United States and Canada, which produces pale yellow flowers in spring.

<i>Aristolochia maxima</i>

Aristolochia maxima is a plant species native to Central and South America, naturalized in southern Florida. Common names include Florida Dutchman's-pipe (US), canastilla (Guatemala), guaco, and tecolotillo (Mexico). In Florida, it grows in hammocks in the Everglades at elevations below 50 m.

Calycolpus warscewiczianus is a plant species native to Nicaragua, Costa Rica, Panamá and Venezuela.

Randia nicaraguensis is a plant species endemic to Nicaragua. It occurs in tropical drought-deciduous forests at elevations below 850 m.

Dendrobangia is a genus of flowering plants in the family Metteniusaceae. It was formerly placed in the family Cardiopteridaceae. It was described as a genus in 1896.

Brickellia glandulosa is a Mesoamerican species of flowering plants in the daisy family. It is widespread from San Luis Potosí south to Nicaragua.

<i>Erechtites valerianifolius</i>

Erechtites valerianifolius, common name tropical burnweed is a New World species of plants in the sunflower family. It is native to Mexico, Central America, South America, and the West Indies. It is also naturalized as a weed in much of the tropical Old World.

Rubus coriifolius is a Mesoamerican species of brambles in the rose family. It grows in central and southern Mexico and Central America.

Xyris baldwiniana, common name Baldwin's yelloweyed grass, is a North American species of flowering plant in the yellow-eyed-grass family. It is native to southern Mexico (Chiapas), Central America, and the southeastern and south-central United States.
