Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Cockspur Hawthorn - Possum-haw - Green Hawthorn Shrubland

Colloquial Name: Haw-Haw-Haw Shrubland :-)

Hierarchy Level:  Association

Type Concept: This association consists of upland shrublands dominated by Crataegus spp. (Crataegus viridis, Crataegus crus-galli) with Ilex decidua. Stands of this vegetation are primarily found on relatively calcareous soils. This association occurs on moist soils of mesic slopes. The distribution of this association is primarily localized in east-central and eastern Oklahoma. In addition, this association is tentatively assigned to Arkansas.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: In Oklahoma, this apparently represents the upland part of Hoagland''s type (Crataegus crus-galli - Ilex decidua - Crataegus viridis shrubland association). Crataegus viridis occurs with Crataegus crus-galli in the uplands (B. Hoagland pers. comm.).
