The woodlands are primarily deciduous with a few evergreens infrequently mixed. Slope: 15 to 30 percent. Aspect: Northeast. Soil: The primary soil type in the area of this collection is classified as Rockland Series sandstone (Rc). The Rockland series consists of well drained soils formed in loamy colluvium from rotational landslides on slopes of stream valleys and dissections of ground moraines. Saturated hydraulic conductivity is moderate in the upper part of the profile and moderately slow in the lower part. Slopes range from 18 to 70 percent. Some pedons have buried leaves, twigs, and moss. Mass soil movement has left random remnants of soil structure from prior upslope soil development and has buried tree branches, leaves and moss. The upper 0-2 cm of soil contains slightly decomposed organic matter while lower soils layers to a depth of 58 cm are comprised of dark reddish-brown to brown silt loam and are moderately acidic. Below 58 cm the soils are generally dark reddish-brown silt loam and strongly to moderately alkaline. (Source:California Soil Resource Lab/NRCS Official Soil Series Descriptions). Geology: The underlying geology of this area is of Pennsylvanian origin and characterized as Pottsville Formation. It is characterized by light-gray thin to thick-bedded quartzose sandstone and conglomerate containing interbedded dark-gray shale, siltstone, and coal. Mapped on Lookout Mountain, Blount and Chandler Mountains, and Sand Mountain northeast of Blount County, and on the mountains of Jackson, Marshall, and Madison Counties north and west of the TN river.

Simmers. Described as a broad-leaved form of M. fistulosa, generally intermediate between M. fistulosa and M. clinopodia, with probable hybrid origin. Typcial habitat is mesic woods and edges on lowlands. In contrast to M. fistulosa, this taxon has longer petioles (usually 2-3 cm versus 0.5-2.0 cm), lower leaf surfaces with scattered spreading hairs, and corollas are paler pink at tips to almost white with peak flowering occurring prior to M. fistulosa by approximately 1-2 weeks. Leaves are rather rugose, where upper leaf tissue between veins is visibly raised. This accession represents genetics from northern Indiana (Potato Creek State Park). Plants at the collection site in nature peaked flowering near 8 July 2019 where flower colors were more lavender in sun but pale in shade (Namestnik, S., personal communication, 15 July 2020). Peak fruiting occurs mid-August. Average height of plants sampled in nature estimated at 4.5' in height. | 2097752 | Ames 35216 |
