Floral Scent Composition of 41 Malagasy Bulbophyllum Orchid Species

Silvia Artuso's dataset from figshare, last updated March 2026, contains floral scent data for 41 species of Malagasy Bulbophyllum orchids. It includes 297 detected volatile organic compounds (VOCs), with 225 being species-specific. The data was used to infer evolutionary patterns of scent traits across a lineage with a crown age of approximately 12.7 million years.

Use Cases

• Modeling floral scent trait evolution based on phylogenetic comparative methods mentioned in the description
• Analyzing the diversity and specificity of 297 volatile organic compounds across orchid species
• Investigating the role of bioactive scent compounds in pollinator attraction for Malagasy Bulbophyllum
• Testing evolutionary models (e.g., Ornstein-Uhlenbeck) for constrained trait evolution in plant lineages

Strengths

• Includes data for 41 distinct orchid species
• Covers 297 detected volatile organic compounds
• Provides phylogenetic context for a lineage with a crown age of ~12.7 million years

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
