Climbing palms; leaves with a whip-like extension of the rachis (cirrus) containing barb-like hooks.
|1b.||Not climbing; leaves without a cirrus.|
|2a.||Cultivated, or naturally-occurring and most often found along beaches; stems often markedly curved; woody coconuts >20 cm diameter.||Cocos nucifera|
|2b.||Naturally-occurring in a variety of habitats, rarely along beaches; stems usually straight; fleshy or woody fruits <6 cm diameter.|
|3a.||Crownshaft, of closed (or partially closed) leaf sheaths, present; leaflets spreading in different planes (appearing plumose) or not.|
|4a.||Leaves plumose, with leaflets spreading in different planes.|
|5a.||Stems generally >30 cm (to 60 cm) diameter; crownshaft conspicuous, of closed leaf sheaths; inflorescences borne below the leaves.|
|6a.||Peduncular bract shorter than the crown-shaft; on wet soil in forest or open savanna, disturbed areas, also cultivated.||Roystonea regia|
|6b.||Peduncular bract > the crown-shaft; found on flooded soils in coastal swamps and estuaries.||*Roystonea dunlapiana|
|5b.||Stems usually smaller; crownshaft open, short; inflorescences borne among the leaves.|
|7a.||Palms of the coastal plain of N. Belize, usually near the sea; leaflets somewhat glaucous, with brown scales beneath; inflorescence branched to 5 orders.||Pseudophoenix sargentii|
|7b.||Widespread palms; leaflets not glaucous, without brown scales; inflorescence branched to 1-2 orders.||Gaussia maya|
|4b.||Leaves not plumose, leaflets in 1 row per side, not spreading in different planes (the tips may be pendulous, but not plumose).|
|8a.||Montane palms with a partially closed (for 1/3 to 1/2 the length of the leaf sheaths), purplish or purple-green crownshaft; stem brownish; flowering branches not densely pubescent.||*Prestoea acuminata|
|8b.||Montane or lowland palms with conspicuously closed, green or yellowish crownshaft; stem gray; flowering branches densely pubescent.||Euterpe precatoria|

|9a.||Leaves irregularly divided into wide leaflets with serrated apical margins; stems to 20 cm diameter; fruits covered with pyramidal low, poorly drained soils near the coast.||Manicaria saccifera|
|9b.||Leaves regularly divided into many narrow, entire leaflets; stems usually >30 cm diameter; fruits smooth; on slopes or lowlands on moderate to well-drained soil.|
|10a.||Margins of leaf sheath and petiole naked; male flowering branches short, <15 cm; endocarp fibers in clusters.||Attalea cohune|
