The leaf of Tolnziea Menziesii (Pursh) T & G first attracted my attention a number of years ago because of the unusual structure and vascularization of its blade. More recently I have surveyed its nonvascular tissues and vein-spacing and a brief report is here presented. This species is an herbaceous perennial belonging to the Saxifragaceae, and is a near relative to Heuchera. Its lower leaves may live over the winter in areas where the plant grows naturally and the flowering stems reach a height of 2-3 feet. This species has attracted attention because of its habit of developing new plants from leaves at the junction region of blade and petiole.
