Trachycarpeae is a tribe of palms in subfamily Coryphoideae of the plant family Arecaceae. [1] [2] It has the widest distribution of any tribe in Coryphoideae and is found on all continents (except Antarctica), though the greatest concentration of species is in Southeast Asia. [3] Trachycarpeae includes palms from both tropical and subtropical zones; the northernmost naturally-occurring palm is a member of this tribe ( Chamaerops humilis ). [4] Several genera can be found in cultivation in temperate areas, for example species of Trachycarpus , Chamaerops , Rhapidophyllum and Washingtonia . [5]

Description

Palms in this tribe have palmate leaves with induplicate folds (reduplicate in Guihaia ). [3] Plants may be tall, single-stemmed trees (e.g. Copernicia , Brahea , Pritchardia ), acaulescent with short, squat trunks (e.g. Maxburretia , Johannesteijsmannia ), multi-stemmed (e.g. Rhapis , Acoelorraphe ) or branched and prostrate (e.g. Serenoa ). These palms flower regularly throughout their lives (pleonanthic) and may be dioecious, monoecious or hermaphroditic. [3]

Taxonomy

Trachycarpeae is one of eight tribes in the subfamily Coryphoideae. [6] The tribe is monophyletic, but phylogenetic studies have yet to reveal its closest relatives, though they could be the Phoeniceae, or the Sabaleae and Cryosophileae. [3] Initially described as tribe 'Livistoneae', the name Trachycarpeae has priority. [3] In previous classifications, all the members of this tribe were included in tribe Corypheae. [7]

Trachycarpeae is divided into two subtribes: Rhapidinae have flowers with three separate carpels, whereas in subtribe Livistoniinae the flower carpels are free at the base, but the styles are fused together. [3] All genera in Rhapidinae are native to the Old World, except North American Rhapidophyllum. Livistoninae are widely distributed in both the New World and Southeast Asia and Australia. A single species ( Livistona carinensis ) has its main area of distribution in Africa, with Chamaerops humilis extending into northern Africa. Several genera in this tribe have yet to be allocated to a subtribe, due to a lack of convincing data from phylogenetic studies. [6]

Rhapidinae [3] [6]

Livistoninae [3] [6]

Unplaced genera [3] [6]

The above classification was published prior to the recognition of the genera Saribus and Lanonia; however, both are clearly members of subtribe Livistoniinae. Saribus includes species formerly in Livistona and monotypic Pritchardiopsis , [8] while Lanonia species were previously included in Licuala. [9] [10]

<i>Livistona</i> Genus of palms

Livistona is a genus of palms, the botanical family Arecaceae, native to southeastern and eastern Asia, Australasia, and the Horn of Africa. They are fan palms, the leaves with an armed petiole terminating in a rounded, costapalmate fan of numerous leaflets.

<span class="mw-page-title-main">Fan palm</span> Index of plants with the same common name

Fan palm as a descriptive term can refer to any of several different kinds of palms (Arecaceae) in various genera with leaves that are palmately lobed. Most are members of the subfamily Coryphoideae, though a few genera in subfamily Calamoideae also have palmate leaves. Fan palm genera include:

<i>Thrinax</i> Genus of palms

Thrinax is a genus in the palm family, native to the Caribbean. It is closely related to the genera Coccothrinax, Hemithrinax and Zombia. Flowers are small, bisexual and are borne on small stalks.

<i>Colpothrinax wrightii</i> Species of palm

Colpothrinax wrightii, the palma barrigona, is a species of flowering plant in the family Arecaceae.

<i>Cryosophila</i> Genus of palms

Cryosophila is a genus of medium-sized fan palms that range from central Mexico to northern Colombia. Species in the genus can be readily distinguished from related genera by their distinctive downward-pointing spines on the stem, which are actually modified roots. They are known as the "root spine palms".

<span class="mw-page-title-main">The Palmetum, Malakpet</span>

The Palmetum is a specialized botanical garden located in the Malakpet area, Hyderabad, in Telangana, which features only one family of plant: the palms.

<span class="mw-page-title-main">Coryphoideae</span> Subfamily of palms

The Coryphoideae is one of five subfamilies in the palm family, Arecaceae. It contains all of the genera with palmate leaves, excepting Mauritia, Mauritiella and Lepidocaryum, all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae. However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds, while Calamoid palms have reduplicate leaf folds. Pinnate leaves do occur in Coryphoideae, in Phoenix, Arenga, Wallichia and bipinnate in Caryota.

<span class="mw-page-title-main">Corypheae</span> Tribe of palms

Corypheae is a tribe of palm trees in the subfamily Coryphoideae. In previous classifications, tribe Corypheae included four subtribes: Coryphinae, Livistoninae, Thrinacinae and Sabalinae, but recent phylogenetic studies have led to the genera within these subtribes being transferred into other tribes. Tribe Corypheae is now restricted to the genus Corypha alone.

<span class="mw-page-title-main">Cryosophileae</span> Tribe of palms

Cryosophileae is a tribe of palms in the subfamily Coryphoideae. The tribe ranges from southern South America, through Central America, into Mexico and the Caribbean. It includes New World genera formerly included in the tribe Thrinacinae, which was split after molecular phylogenetic studies showed that Old World and New World members of the tribe were not closely related.

Borasseae is a tribe in the palm subfamily Coryphoideae. The tribe ranges from southern Africa and Madagascar north through the Arabian Peninsula to India, Indochina, Indonesia and New Guinea. Several genera are restricted to islands in the Indian Ocean. The two largest genera, Hyphaene and Borassus, are also the most widespread.

<span class="mw-page-title-main">Chuniophoeniceae</span> Tribe of palms

Chuniophoeniceae is a tribe of palms in subfamily Coryphoideae of plant family Arecaceae. The four genera within the tribe are morphologically dissimilar and do not have overlapping distributions. Three of the genera are monotypic, while the fourth genus (Chuniophoenix) has three species.

Lanonia is a genus of fan palms, in the tribe Trachycarpeae. It has a recorded native range from southern China to Indo-China and is also found in Java.
