CEGL008563 Sporobolus vaginiflorus var. ozarkanus Ozark Grassland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Ozark Dropseed Ozark Grassland

Colloquial Name: Ozark Annual Grass Glade

Hierarchy Level:  Association

Type Concept: This broadly defined type represents vegetation dominated by Sporobolus vaginiflorus var. ozarkanus in the Ozarks of Arkansas and presumably Oklahoma. Recognition of and/or need for this type by Missouri is unclear. This placeholder temporarily represents vegetation from the Ozarks. It will be better developed as more information becomes available.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This concept was formerly included in a placeholder, ~Sporobolus vaginiflorus (var. ozarkanus, var. vaginiflorus) - Hypericum dolabriforme Grassland (CEGL004339)$$, which represented both Ozark - Ouachita and Southern Ridge and Valley occurrences. This has now been divided, with this (CEGL008563) becoming the Ozarkian part (type not needed for Ouachitas).
