Abstract
An open Lebanon limestone cedar glade complex with abundant Grindelia lanceolata was sampled to determine frequency and life form of associated vascular plant taxa and density of reproductive and nonproductive plants of G. lanceolata, a short-lived monocarpic perennial. Species with >50% frequency in the 85 1 m × 1 m sample plots were G. lanceolata (100%), Sporobolus vaginiflorus (96.5%), the cedar glade endemic Dalea gattingeri (91.8%), Ruellia humilis (64.7%), Isanthus brachiatus (63.3%), and the cedar glade endemic Pediomelum subacaule (56.5%). Forty-four of the 54 taxa in the 85 plots had a frequency of ≤20%. More than 75% of the taxa are hemicryptophytes (40.7%) or therophytes (35.3%). Only 11.0% of the 4,164 plants of G. lanceolata counted had flowered. The G. lanceolata type is a vegetation unit of open cedar glades that has received little attention.
