Wood Anatomy Of Lamiaceae. A Survey, With Comments On Vascular And Vasicentric Tracheids, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Quantitative and qualitative data are presented for 44 collections representing 42 species in 27 genera. Lamiaceae basically have: vessels with simple perforation plates; vessel-to-vessel pitting alternate; imperforate tracheary elements all libriform fibers, fibers commonly septate; axial parenchyma scanty vasicentric; rays Heterogeneous Type IIB. These features ally Lamiaceae closely with Verbenaceae. In addition to the Mesomorphy ratio (based on vessel element dimensions), features that indicate wood xeromorphy in Lamiaceae, in probable increasing order of importance are: presence of indistinct to marked growth rings; presence of helical thickenings in vessels; presence of vasicentric or vascular tracheids; presence of vessel groups averaging three …

Monardella Stebbinsii (Lamiaceae), A New Serpentine Endemic Species From The Northern Sierra Nevada, Plumas County, California, Clare B. Hardham, Jim A. Bartel Jan 1990

Monardella Stebbinsii (Lamiaceae), A New Serpentine Endemic Species From The Northern Sierra Nevada, Plumas County, California, Clare B. Hardham, Jim A. Bartel

Aliso: A Journal of Systematic and Floristic Botany

Monardella stebbinsii (Lamiaceae ), a new species from the northern Sierra Nevada of Plumas County, California, is described and illustrated. Characterized by ovate leaves, multiple verticillasters per infiorascence, a matlike habit, reddish papery bracts, and purplish-red leaves with a soft white pubescence, the species is not closely related to any other species of the genus. The new species is apparently restricted to the central portion of a serpentine outcrop located north and east of the confluence of the North Fork of the Feather River and its East Branch.
