Floral attractants 
The tepals of all species observed are yellowish (old ivory) to yellowish orange in 
colour to the human eye. Dull amber or rusty tones are due to the darker-coloured, 
simple trichomes on the tepals. Persoonia arborea, P. laurina, P. siibvelulina and P. silvatica 
have glossy, white anthers. In all other taxa examined the anthers are yellowish to the 
human eye often turning a dried mustard colour with age. The tepals of P. glaucescens 
were observed to change from a deep apricot to a light, straw yellow as the individual 
flowers age. The yellow tepals of P. lanceolata become progressively paler with age.
