GROUP IV Stems
slender, cane like, usually green or brown, rarely taller than 5 m
(* potential species)
|30a.||Stems green and leaves tightly clustered at stem apex.|
Stems 1.5-3 cm diameter, to 3 m tall, forming open, sprawling colonies on limestone hilltops, ridges (dense in burned places); stems, sheath, petiole, andrachis often glaucous; leaflets usually 22–42 per side, <3 cm wide; stems 2–3 cmdiameter; female, male infls. with 10-35 branches.
|31b.||Stems smaller or larger, forming tight clusters or ± closed clumps, not sprawling; plant not glaucous; leaflets usually <22 per side; most commonly found in lowlands.|
|32a.||Stems stout, 210 cm diameter, to 7 m tall; leaflets wide (310 cm) and long (to 70 cm), to 25 per side, with several prominent primary veins above; female infl. with up to 20 branches, male infl. with up to 50 branches.||Chamaedorea tepejilote|
|32b.||Stems slender, 12 cm diameter, to 3 m tall; leaflets narrow (<3 cm) and short (to 35 cm), 518 per side, with one primary vein; female, male infl. with 4-12 branches.||Chamaedorea seifrizii|
|30b.||Stems not green (sometimes green in Geonoma deversa, but then leaves loosely clustered at stem apex).|
|33a.||Leaflets numerous (usually >20/side, at least >3/side), without windows between the folds and the rachis.|
formed by closed, or partially closed leaf sheaths present, stem to 20+ cm
diameter; leaflets + uniform in size, linear.
Stem gray; green crownshaft formed by closed leaf sheaths; infl. axes densely pubescent.
Stem brown, green or purplish crown shaft mostly open; infl. axes not densely pubescent.
Crownshaft absent; to 20 leaves present; leaflets often irregularly-shaped; stem light brown, flowers in pits on the infl.
|33b.||Leaflets usually <4 per side, (with small windows between the folds on either side of the rachis in Reinhardtia).|
clustered at the apex, with compound leaflets having small windows between
the folds on either side of the rachis.
|37a.||Stems thick, c. 6-7 cm diameter; leaf blades > 1 m long.||Reinhardtia latisecta|
|37b.||Stems c. 1.5 cm diameter; leaf blades <1 m. (usually <0.5 m).||Reinhardtia gracilis|
|38a.||Leaves large: leaf rachis 11-23 cm long, with 1422 nerves on each side; the lower pinnae 14.525 cm long.||Reinhardtia gracilis var. gracilis|
|38b.||Leaves small: leaf rachis 3.5-6 cm long, with 811 nerves on each side; the lower pinnae 8.512 cm long.||Reinhardtia gracilis var. gracilior|
Leaves loosely spread apart along the stem, without windows; stem <3 cm diameter.
