This common bamboo has no name

and is not known to science at all

The most common bamboo in Madagascar was named in 1998

• Swelling at base petiole / leaf sheath junction

• Damping properties?

• Calaminae only

Rattans are tropical

climbing palms

“species” are still defined and documented

by groups of herbarium specimens

Baseline diversity inventory enables species utilization and conservation and is necessary to plan interventions to support restoration, soil protection, and renewable energy
