“Loss of indusium, dimorphism, areolate venation, and reduced blade dissection have occurred repeatedly along many evolutionary lines in Dryopteridaceae.”

“The surface of the cell is coarsely areolate, with a pore in each areole.”

“In crustose areolate lichens, the edges of the areolas peel up from the substrate and appear leafy.”

“Even small branches that are torn or cut will quickly retract into the areolar fat causing hematomas and ecchymosis during heparinization.”

“Loose areolar tissue is the least solid, with gelatinous material among its fibres.”

“The ventral paratenon consists of fatty mesenteric-like areolar tissue that is rich in blood vessels that nourish the tendon.”
