In secondary upper montane forest above the Río Quindío. Bamboo
common in places; this clump with many culms in flower, some at
anthesis, mostly past. Culms erect to leaning at the base, scandent and
hanging above, 2-3 cm in diameter, 8-10 m long. Internodes scabrid
above the culm leaves, pubescent-hispid or glabrous below the nodal
line, often with a deeper green band below the node, shallowly sulcate
above the bud/branch complement, 24-27 cm long. Culm leaves with
the sheath fused at the base for about 2 cm; girdle present, at base with
a ring of cilia all around the node. Branching extravaginal. Central bud
triangular, subtended by at least 2-3 rows of smaller subsidiary buds in a
constellate arrangement; nodal line dipping only slightly; supranodal
ridge well developed, internode often wider here than at the nodal line;
root primordia developed in the nodal area at nodes in the first 2 m or so
of the culm. Foliage leaves with the midvein of the blade excentric.
Inflorescences narrow, branches appressed. Treated with 70% EtOH.
