Veracruz: ca. 4 km past Tonalaco on the road to Oxtlapa,
lower slopes of Cofre de Perote. 2250 m. 97° 05' 45"W,
19° 25' 40"N.
Cloud forest and clearings. Plants In discrete clumps
that may be as much as 2 m across. Culms more or less
erect but arching at tips, to 5-6 m tall, to 4 cm basal
diameter. Intemodes hollow, 19-27 cm long, the walls ca.
0.5 cm thick on a culm 3.5 cm in diam., cylindrical, dark
olive green becoming maroon with age. Buds evident even
on the lowermost nodes, but they appear on alternate sides
of the culm and extending more or less halfway around the
node, then filling at successive nodes until a complete
verticel is formed about mid-culm. Branching initially
intravaginal, but the pressure of the developing verticel
of branches quickly pushes the culm leaf away; branches
erect then arching out and away from the culm.
