Minni ritchi is a type of reddish-brown bark that continuously peels in small curly flakes, leaving the tree looking like it has a coat of red curly hair. Brooker and Kleinig (1990) formally described it as a bark type in which "the outer rich, red-brown smooth bark splits both longitudinally and horizontally, the free edges rolling back without completely detaching to expose new green bark beneath".

A number of species of Acacia and Eucalyptus have minni ritchi bark, including:

• Acacia curranii
• Acacia cyperophylla (creekline miniritchie)
• Acacia delibrata
• Acacia gracillima
• Acacia grasbyi (miniritchie)
• Acacia monticola
• Acacia rhodophloia
• Acacia trachycarpa
• Eucalyptus caesia (gungurru, 'Silver Princess')
• Eucalyptus crucis (narrow-leaved silver mallee)
• Eucalyptus minniritchi
• Eucalyptus orbifolia
