cremose

Cremose is a term used in botany to describe a plant organ that is sticky or gummy in texture. This characteristic is often due to the presence of secreted mucilage or resinous substances on the surface of the plant part. The stickiness can serve various ecological functions, such as deterring herbivores, aiding in seed dispersal by trapping insects, or protecting the plant from desiccation.

Examples of cremose structures can be found in different plant species. Certain buds, particularly those of trees like horse chestnut or poplar, are known for their sticky, resinous coverings, which protect the delicate developing leaves from frost and mechanical damage. Some flower parts, such as the stigmas of certain plants, may also be cremose to effectively capture pollen. In some cases, the entire surface of a young stem or leaf might exhibit a cremose quality. The composition and properties of the sticky exudate can vary significantly among species, reflecting different evolutionary adaptations to their environments. The study of cremose features contributes to our understanding of plant defense mechanisms and reproductive strategies.
