Narrative
Big bluestem is a tall, warm-season, perennial, native grass with stiff, erect culms; flattened and keeled sheaths; membranous ligules; and flat or folded leaf blades. Refuge big bluestem is relatively shorter than other varieties of big bluestem. Average total height is 4.5 to 5.5 feet tall. Big bluestem has developed a very efficient spreading root system which may reach depths of 5-8 feet (150-200 cm) in northern latitudes, and 6-8 feet (180-240 cm) or more in the southern part of its natural range. Although short rhizomes may be present, it usually makes a bunch type growth. This growth is columnar and dense with very little lodging. Refuge big bluestem has the ability to withstand wind, snow and ice in extreme conditions. These characteristics make it a good selection for buffer and wildlife plantings. Big bluestem is one of the most widespread and important forage grasses of the North American tallgrass prairie region. Big bluestem occurs on sub-irrigated lowlands, nearly level to gently undulating glacial till plains, overflow sites, level swales and depressions, residual and glacial uplands, and stream terraces and bottomlands along rivers and tributaries.

Comment:
the original spelling is permissible under Shenzhen ICN Rec. 60C.2, since the given name Gerard or Gérard, which dates at least to the Early Middle Ages when Latin was the international language of Europe, has a well-established latinized form and is not correctable under Shenzhen ICN Art. 60.8

Pedigree
Description:
Three hundred and seventy collections were vegetatively collected from 190 counties throughout the Ozark region of Missouri, Arkansas, Oklahoma, and Illinois. Each collection was increased vegetatively in the greenhouse and planted into an evaluation nursery with two replications and six plants per collection in each replication. Each plant was evaluated independently and ten collections. Selected plants were vegetatively removed, increased vegetatively in the greenhouse, and isolated in an evaluation nursery containing approximately one hundred plants. Three individual plants representing three collections, accession numbers 9056902, 9056906 and 9056906, were selected for their short, columnar shape. These three plants were again vegetatively removed, vegetatively increased in the greenhouse, and planted into a crossing block. Seed from this block was used to establish the increase (G1) field. Selection Criteria: The Refuge germplasm was selected and isolated because of its shorter than average height and its stiff stem that prevented lodging while being evaluated in an assembly of 370 collections of big bluestem. Comparison of Refuge Germplasm big bluestem to 'Rountree' big bluestem was Refuge was approximately two and a half feet shorter and exhibited considerable resistance to lodging from maturity throughout the dormant season with standability to spring. The Refuge Germplasm selection has characteristics of being very good for wildlife habitat and also works well in buffers and filters.
