| In Betula the bracts of the catkins are deciduous, and the mature catkin shatters to release the winged fruit. |
| Peridon and catkin, and Mr. Pempton took their usual places. |
| Ash, beech, acorn, conker and catkin have all been chopped. |
| Scales of the fertile catkin ovate, 2-flowered, coriaceous, persistent. |
| Wood injury, catkin injury, and pistil injury will be treated separately. |
| Trees in the partially protected orchard fared somewhat better in regard to catkin injury than those in the more exposed orchard. |
