Ceratonia oreothauma is a species of tree native to Oman and Somaliland.
Ceratonia oreothauma is a small tree with gnarled branches and rough bark which grows up to 8 meters high. It is evergreen, with singly-pinnate leaves bearing up to 20 leaflets. [2]
Ceratonia oreothauma flowers in March and April. Flowers are either purely male or purely female, with minute and sterile primary anthers. [3]
Ceratonia oreothauma has two widely separated populations which are classified as separate subspecies. C. oreothauma ssp. oreothauma is found in a single valley on Jebel Aswad in the eastern Hajar Mountains of Oman between 900 and 2000 meters elevation. [2] C. oreothauma subsp. somalensis occurs in the mountains of Somaliland between 1500 and 1800 meters elevation. [4]
The population trend of subspecies oreothauma is not well understood. The eastern portion of its population is in Wadi Siren Nature Reserve. The northwestern portion of the population is not regenerating. The subspecies is considered Vulnerable. [5]
The known populations of subspecies somalensis in Somaliland are very small. Its habitat is unprotected, and is under pressure from human use. The subspecies is considered Endangered. [6]
Ceratonia has one other species, Ceratonia siliqua or carob, which is distributed around the Mediterranean. C. oreothauma is morphologically distinct from C. siliqua. In addition the pollen grains of C. oreothauma are slightly smaller than those of C. siliqua and are tricolporate rather than tetracolporate. [4]
The carob is a flowering evergreen tree or shrub in the Caesalpinioideae sub-family of the legume family, Fabaceae. It is widely cultivated for its edible fruit, which takes the form of seed pods, and as an ornamental tree in gardens and landscapes. The carob tree is native to the Mediterranean region and the Middle East. Portugal is the largest producer of carob, followed by Italy and Morocco.
Magnolia guatemalensis is a tree found in the highlands and mountains of Guatemala, Chiapas, El Salvador, and Honduras. It is considered an indicator species of the cloud forest.
Alnus jorullensis, commonly known as Mexican alder, is an evergreen or semi-evergreen alder, native to eastern and southern Mexico, Guatemala, and Honduras. Although previously reported from the Andes, further collections showed these to be the similar species A. acuminata, commonly found in South America.
Prosopis alba is a South American tree species that grows in central Argentina, the Gran Chaco ecoregion, and part of the Argentine Mesopotamia, as well as Bolivia, Chile, Paraguay, and Peru. It is known as algarrobo blanco in Spanish. Spanish settlers gave it that name because of its similarity to the European carob tree. Other common names come from Guaraní, including ibopé and igopé.
Ceratonia is small genus of flowering trees in the pea family, Fabaceae, endemic to the Mediterranean region and the Middle East. Its best known member is the carob tree, which is cultivated for its edible pods and has been widely introduced to regions with similar climates. The genus was long considered monotypic, but a second species, Ceratonia oreothauma, was identified in 1979 from Oman and Somalia. The genus is in subfamily Caesalpinioideae and tribe Umtizieae.
Agathis robusta subsp. nesophila, the New Guinea kauri, is a subspecies of conifer native to the highlands of Papua New Guinea. It grows in the Eastern Highlands and Owen Stanley Range of eastern New Guinea and the highlands of New Britain at elevations of 900–1980 m. Although long known, it has only relatively recently (1980) been described as a subspecies of Agathis robusta. It is also known by the synonym Agathis spathulata. It is threatened by habitat loss.
Podocarpus matudae is a species of conifer in the family Podocarpaceae. It is found in Guatemala, El Salvador, Honduras and Mexico.
Cratoxylum formosum is a species of flowering plant in the Hypericaceae family. Its commercial name in timber production is "mampat".
Damburneya roberto-andinoi is a species of plant in the family Lauraceae. It is endemic to Honduras. It is a tree growing up to 15 meters tall.
Chisocheton cumingianus is a tree in the family Meliaceae. The tree is named for the English naturalist Hugh Cuming. Habitat is rain forests from sea-level to 1,300 metres (4,300 ft) elevation. C. cumingianus is found from India and tropical China through Indochina and throughout Malaysia. In the Philippines, the seeds of C. cumingianus are used to make a non-drying oil either for traditional medicine or as fuel for oil lamps.
Planchonella reticulata is a flowering plant in the sapodilla family, Sapotaceae. It is a shrub or tree endemic to east-central New Caledonia. The specific epithet refers to the reticulate venation on the leaves.
Gaultheria fragrantissima is a species of flowering plant native to southern and southeastern Asia. It is commonly known as fragrant wintergreen or dhasingre.
Hanak's dwarf bat or Hanak's pipistrelle is a species of bat only found in Cyrenaica, Libya and Crete, Greece.
The Somali montane xeric shrublands is a desert and xeric scrubland ecoregion in Somalia. The ecoregion lies in the rugged Karkaar Mountains, which run parallel and close to Somalia's northern coast on the Gulf of Aden, and follows coast from Cape Guardafui south to Eyl on the Arabian Sea.
The Southwestern Arabian foothills savanna, also known as the Southwestern Arabian Escarpment shrublands and woodlands, is a desert and xeric shrubland ecoregion of the southern Arabian Peninsula, covering portions of Saudi Arabia, Yemen, and Oman.
