Flecks

Medullary rays appear as flecks when wood is quartersawn. These typically have their brightness peak out of phase with respect to the surrounding surface, so they look really evident when lighting the surface from different directions. Below some examples:

Maple, European (from Seralvo)- PZC = 15.6
Beech, European (from [Source 3])- PZC = 9.5
Iroko (from [Source 37])- PZC = 23.0
Sapele (from Seralvo)- PZC = 22.3
Purpleheart (from Seralvo)- PZC = 9.7
Ziricote (from Seralvo)- PZC = 6.7
Bocote (from [Source 22])- PZC = 11.8
London Plane (from Seralvo)- PZC = 14.9
Bog Oak (from [Source 24])- PZC = 11.2
Mulberry (from [Source 23])- PZC = 20.4
Makore (from P. Hinds)- PZC = 19.9
Louro Faia (from Seralvo)- PZC = 17.2
Cherry, Black (from P. Hinds)- PZC = 18.4
Osage Orange, Green (from Paul Veerkamp)- PZC = 19.4
Mahogany, Honduras (from Seralvo)- PZC = 24.9
Elm (from [Source 27])- PZC = 14.9
Koto (from [Source 27])- PZC = 12.9
Ash, European (from Seralvo)- PZC = 14.5
Walnut, European (from M. Zanichelli)- PZC = 19.2
Louro Preto (from [Source 26])- PZC = 11.5
Tineo (from Evolution Panels and Doors)- PZC = 12.3
Movingui (from [Source 35])- PZC = 18.7
Paldao (from [Source 28])- PZC = 24.9
Oak, Red (from P. Hinds)- PZC = 11.4
Black Locust (from Tim Connell)- PZC = 16.6
