Overview of cultivated and wild species of the Caesalpiniaceae family (Fabaceae S.L.) in the emirate of Fujairah (United Arab Emirates)

The article provides an overview of the family Caesalpiniceae (Fabaceae s. l.) in the flora of the emirate of Fujairah, located in the mountainous northwestern part of the Arab Emirates (UAE). We have been studying the flora of the emirate for a number of years, from 2017 to 2022. Based on field studies, surveys of irrigated gardens, public parks, urban plantations and nurseries, herbarium materials and literature data, the species composition of palm trees (Arecaceae) identified here was studied. As a result, the article provides an overview of wild and cultivated palms (native and introduced) that are found in nature or cultivated in open ground conditions in the emirate of Fujairah. Families, genera and species are arranged in alphabetical order, with separate wild and feral species and cultivated non-wild species. We also took into account our data on species found only in plant nurseries. The list contains 25 species from 11 genera. Indigenous and alien, cultivated (ergasiophytes) and running wild from culture (ergasiophygophytes) or spreading independently (xenophytes) are indicated. Parkinsonia aculeata L. and Senna occidentalis (L.) Link are recorded as a new alien species for Fujairah, a number of species – Bauhinia purpurea L., Bauhinia variegata L., Caesalpinia pulcherrima (L.) Sw., Cassia fistula L., Delonix regia (Bojer ex Hook.) Raf., Senna alata (L.) Roxb., Senna surattensis (Burm. f.) H.S. Irwin & Barneby and Tamarindus indica L. for the first time as a wild or alien alien species for Fujairah, the United Arab Emirates and Arabia as a whole.
