From: Isolation of intact sub-dermal secretory cavities from Eucalyptus
Quantification of the abundance of volatile essential oils within the secretory cavity lumena of Eucalyptus. Estimated lumen volume plotted against the volume of oil extracted from each of 20 isolated cavities from fully expanded leaves of Eucalyptus polybractea (open circles; solid regression line), E. globulus (closed circles; dashed regression line) and E. froggattii (grey circles; dotted regression line).
