Angiosperm Wood from the Upper Creataceous of Central California: Part II
Preview not available

Abstract

Three species of fossil wood representing two genera are described. The specimens are from a collection of woods from the Upper Cretaceous Panoche formation of central California. Tetracentronites panochetris sp nov. resembles angiosperm wood in ray structure and vascular pitting but lacks vessels. Plataninium platanoides sp. nov. is similar to the wood of Platanus, and the evidence presented points to a direct relationship. The resemblance between Plataninium californicum sp. nov. and the woods of certain Icacinaceae is discussed, but evidence of relationship is inconclusive.
