Thus the white pine is Pinus strobus, Pinus being the name of the pine genus, and strobus referring to the species known as white pine. The pitch pine, similarly, is Pinus rigida.

The unicellular conifer tracheid should have greater flow resistance per length (resistivity) than the multicellular angiosperm vessel, because its high-resistance end-walls are closer together.

However, tracheids and vessels had comparable resistivities for the same diameter, despite tracheids being over 10 times shorter. adhesives for wood () adressbuch der holz-interessenten oesterreich-ungarns mit bosnien und herzegowina.
