Table A2 Measurements and literature sources of floral
dimensions for all non-graminoid flowering species. Floral units
describe the scale at which species were counted in quadrats (flower,
inflorescence, or capitulum in Asteraceae species). ‘l ’ is length
in mm of corolla opening (or receptacle length for capitula), ‘w ’
is width in mm of corolla opening (or receptacle width for capitula),
‘h ’ is height in mm, measured from the receptacle to the longest
sexual organ (stamen or pistil), and ‘V ’ is floral volume in
mm3, calculated using the formula for volume of an
elliptic cylinder
(\(\mathrm{V}\mathrm{\ }\mathrm{=}\mathrm{\ }\mathrm{\pi}\mathrm{\ }\mathrm{\times}\mathrm{\ }\frac{\mathrm{l}}{\mathrm{2}}\mathrm{\ }\mathrm{\times}\mathrm{\ }\frac{\mathrm{w}}{\mathrm{2}}\mathrm{\ }\mathrm{\times}\mathrm{\ }\mathrm{h}\)).
Inflorescence volume was calculated by multiplying floral volume by the
average number of flowers per inflorescence and was left blank when
individual flowers were counted rather than inflorescences. Measurements
were made on five individuals per species, or values were obtained from
literature sources.
