Resumen:
Otatea is a Neotropical woody bamboo genus with thirteen described
species. It is distributed from Mexico to Central America and
northeastern Colombia. In Mexico, the archaeological evidence suggests
that the culms of Otatea have been used for centuries by some ethnic
groups. It is important to explore morphological and anatomical
characters for species identification in woody bamboos as consequence of
its monocarpic nature. Most studies on culm anatomy are centered on
commercially used species describing their physical and mechanical
properties. The aim of this work was to find culm anatomical characters
with taxonomic value. To perform this, we collected internode samples
from adult plants at mid culm of 15 specimens that represent 10
described species and two putative new species of Otatea. Our results
include descriptions of culm anatomy at a cross section accompanied with
images that detail all the structures measured and described.
Additionally, we elaborate a key based on anatomical characters. This
contribution is the first to explore culm anatomy of the genus Otatea in
search for characters with taxonomic value, providing useful evidence
for species identification, including samples from archaeological sites.
