Source History
Collected
04 September 2015.
Black Hawk County, Iowa, United States
Locality: Private property approximately 7 miles northwest of Cedar Falls, T90N R14W SW 1/4 NW 1/4 SE 1/4 Sec. 18.
Coordinates: 42.6040, -92.5428 (Map it)
Elevation: 284m.
Georeference protocol: Lat/lon determined by GPS
Habitat: Wild Habitat
Environment description: High-quality remnant wetland/fen
Number of plants sampled: 7
Associated species: Asclepias incarnata, Lobelia siphilitica, Pycnanthemum virginianum, Eutrochium purpureum, Spiraea alba, Thelypteris palustris, Onoclea sensibilis, Agalinis purpurea, Solidago spp., Gentiana andrewsii, numerous Carex spp., Athyrium filix-femina, and Helianthus grosseserratus. Additional vegetation nearby included Prunus serotina, Vitis riparia, Prunus americana, Prunus virginiana, Cornus racemosa, Juniperus virginiana (few), Acer saccharinum, Saggitaria latifolia, and Ulmus sp. In some areas Phalaris arundinacea is out-competing B. pumila.
Comment: Approximately eight genets noted. Out of eight genets noted, one genet could potentially consist of five additional genets, but due to the clonal nature of B. pumila it is difficult to determine. A total of seven genets were fruiting and thus sampled. Specimens were localized in the SW 1/4 NW 1/4 SE 1/4 in both Aquolls (2) and Clyde silty clay loam soils (5). Regeneration of B. pumila (small seedlings) was not noted likely due to dense vegetation of Phalaris arundinacea.

Narrative
Specimens sampled averaged approximately 278 cm in height, ranging from 250 cm to 330 cm. Female catkins were both green and brown at time of harvest. Little to no fall color at time of seed collection (4 Sept. 2015) with approximately 75% of leaves already dropped. During growout in 2016, samples #699-3 and #699-5 resulted in seedlings that have petiolules (on small seedlings) that average 3-5 mm in length with the leaf apex being rather sharply acute, possibly indicating presence of hybrids. Other samples (#699-1, #699-2, #699-6, and #699-7) seem to exhibit characteristics of B. pumila with densely pubescent leaves and stems, with leaves having the apex usually broadly acute or obtuse to rounded, and essentially leaves being sessile or less than 1mm in length.
