Kerriodoxa J.Dransf. Nannorrhops H.Wendl. Tahina J.Dransf. & Rakotoarinivo DescriptionOutwardly, the palms in the four genera of Chuniophoeniceae appear quite different. Chuniophoenix are small palms from the forest understory with clustered stems; Kerriodoxa is a squat, single-stemmed rainforest palm; Nannorrhops is a sprawling desert palm with branching stems; and Tahina is a massive solitary palm from exposed limestone outcrops.[1][3][2][4] They differ significantly in their flowering strategies, too. Chuniophoenix species flower regularly throughout their lives (pleonanthic) and produce hermaphroditic flowers (rarely single gender); Kerriodoxa are also pleonanthic, but are always dioecious; Nannorrhops stems die after flowering (hapaxanthic), though the much-branched plant survives; Tahina produces a massive terminal inflorescence and dies after fruiting. All Chuniophoeniceae have palmate leaves with induplicate folds and tubular bracts partially enclosing the flowers.[1][2][3][4] TaxonomyChuniophoeniceae is one of eight tribes in subfamily Coryphoideae.[5] The tribe is monophyletic and closely related to tribes Caryoteae, Corypheae and Borasseae, forming the syncarpous clade.[1][5][4][6] In a previous classification, prior to the discovery of Tahina, the three other genera were placed in tribe Corypheae, subtribe Coryphinae, together with the genus Corypha.[7] Coincidentally, Corypha and Tahina both share the strategy of producing a massive display of flowers only once before dying.[4] The four genera have widely disjunct distributions. Chuniophoenix (3 spp.) is found in southern China and Vietnam; Kerriodoxa (1 sp., K. elegans) is restricted to peninsular Thailand; Nannorrhops (1 sp., N. ritchiana) is found in parts of Iran, Afghanistan, Pakistan and the southeastern Arabian Peninsula; while Tahina (1 sp., T. spectabilis) is endemic to a small area of northwestern Madagascar.[1] GalleryReferences1. ^1 2 3 4 {{Cite book|title=Genera Palmarum - The Evolution and Classification of Palms|last=Dransfield|first=John|last2=Uhl|first2=Natalie W.|last3=Asmussen|first3=Conny B.|last4=Baker|first4=William J.|last5=Harley|first5=Madeline M.|last6=Lewis|first6=Carl E.|publisher=Royal Botanic Gardens, Kew|year=2008|isbn=9781842461822|location=|pages=}} {{Taxonbar|from=Q1089595}}2. ^1 2 {{Cite journal|last=Henderson|first=Andrew|date=2015-07-01|title=A revision of Chuniophoenix (Arecaceae)|url=https://biotaxa.org/Phytotaxa/article/view/phytotaxa.218.2.6|journal=Phytotaxa|language=en|volume=218|issue=2|issn=1179-3163}} 3. ^1 {{Cite journal|last=Dransfield|first=John|date=1983|title=Kerriodoxa, a new coryphoid palm genus from Thailand.|url=|journal=Principes|volume=27|pages=3–11|via=}} 4. ^1 2 3 {{Cite journal|last=Dransfield|first=John|last2=Rakotoarinivo|first2=Mijoro|last3=Baker|first3=William J.|last4=Bayton|first4=Ross P.|last5=Fisher|first5=Jack B.|last6=Horn|first6=James W.|last7=Leroy|first7=Bruno|last8=Metz|first8=Xavier|date=2008|title=A new Coryphoid palm genus from Madagascar|url=https://academic.oup.com/botlinnean/article/156/1/79/2418218|journal=Botanical Journal of the Linnean Society|language=en|volume=156|issue=1|pages=79–91|doi=10.1111/j.1095-8339.2007.00742.x|issn=0024-4074|via=}} 5. ^1 {{Cite journal|last=Dransfield|first=John|date=2005|title=A new phylogenetic classification of the palm family, Arecaceae.|url=https://www.researchgate.net/publication/215898364|journal=Kew Bulletin|volume=60|pages=559–569|via=ResearchGate}} 6. ^{{Cite book|title=Borassus L. and the borassoid palms: systematics and evolution, PhD thesis|last=Bayton|first=Ross P.|publisher=University of Reading|year=2005|isbn=|location=|pages=}} 7. ^{{Cite book|title=Genera Palmarum: A Classification of Palms Based on the Work of Harold E.
