Specimens of the two cedar (limestone) glade endemics Petalostemon gattingeri (Leguminosae) and Leavenworthia torulosa (Cruciferae) in the Mohr Herbarium at ALU were not examined in recent taxonomic treatments of these genera. Thus, in Alabama, P. gattingeri is reported in the recent literature only from the northwestern part of the state, and L. torulosa is unreported. However, old specimens in the Mohr Herbarium show that, historically, P. gattingeri grew on “bald prairies” and limestone glades in central Alabama and L. torulosa on limestone glades in northern Alabama. Mohr included the yellow-flowered Leavenworthia aurea in his Plant Life of Alabama, and he incorrectly identified a fruiting specimen of L. uniflora as belonging to this species. We suggest that Mohr mistook fruiting plants of L. uniflora growing at Scottsboro in Jackson County for those that then were assignable to L. aurea (now called L. exigua var. lutea) which he had seen flowering at this site in early spring.
