Floral Scent Composition of 41 Malagasy Bulbophyllum Orchid Species

Malagasy Bulbophyllum orchid floral scent data includes 297 volatile organic compounds (VOCs) detected across 41 species. The dataset was created by Silvia Artuso and last updated in March 2026. It supports phylogenetic comparative methods to investigate scent evolution over approximately 12.7 million years.

Use Cases

• Modeling floral scent trait evolution using phylogenetic comparative methods based on the described PCMs.
• Analyzing the diversity and specificity of volatile organic compounds (VOCs) across orchid species.
• Investigating the role of bioactive scent compounds in pollinator attraction for Malagasy Bulbophyllum.
• Testing hypotheses of bounded versus neutral evolution in floral traits based on the constrained (Ornstein-Uhlenbeck) model results.

Strengths

• Includes 297 distinct volatile organic compounds (VOCs) detected.
• Covers 41 species of Malagasy Bulbophyllum orchids.
• Data supports a novel phylogenetic comparative methods (PCMs) approach for scent evolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (345.3 KB), indicating limited scope.
