(of a lichen) having upright or pendulous branches.
- ‘Lichens are traditionally classified into three growth forms: crustose, foliose, and fruticose.’
- ‘This tome includes detailed entries on more than 800 foliose, fruticose, and crustose lichens; essays on the biology, structure, uses, and ecological significance of these plants; and hundreds of color photographs.’
- ‘Where thriving foliose and fruticose lichens can be found, the environment is clean and healthy.’
- ‘Examples of fruticose microlichens include Calicium, Chaenotheca, Gyalideopsis, and Microlychnus.’
- ‘In foliose lichens there is a lower cortex and in fruticose lichens the lower cortex is replaced by a central one.’
Mid 17th century: from Latin fruticosus, from frutex, frutic- bush, shrub.
