World checklist of bamboo and rattan species
Maria S. Vorontsova
Kew is global centre for plant and fungal diversity research with unrivalled biodiversity collections:7.5 million dried plants1.25 million dried fungi67,000 living seed samples45,000 stored DNA samples85,000 living plants250 science staff
This common bamboo has no name
and is not known to science at all
Valiha diffusa S. Dransf.
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
Botanical field work in Madagascar

Kew herbarium collections are the
foundation of plant classification

Molecular data support
three main lineages of Bambusoideae
Bamboos from a phylogenetic perspective
Plant names change: Thamnocalamus tessellatus is now called Bergbambos tessellata

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