Diagonal And Tangential Vessel Aggregations In Wood: Function And Relationship To Vasecentric Tracheids, Sherwin Carlquist
Diagonal And Tangential Vessel Aggregations In Wood: Function And Relationship To Vasecentric Tracheids, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
The list of families with diagonal ("dendritic" or " flamelike" of other authors) patterns of vessel aggregation is similar to the list of families that have vasicentric tracheids. This paper attempts to deal with apparent exceptions. Because of recent reports of vasicentric tracheids, the families with diagonal vessel aggregations are all also on the list of families with vasicentric tracheids with the exception of four families. Genera of those four families are studied to see if a relationship between vasicentric tracheids and diagonal vessel aggregations does hold. Of the families not on both lists, Leitneriaceae (Leitneria), Melastomataceae ( …
