Here's a breakdown:

* Corniferous: Refers to trees that produce fruits with a hard, stony seed inside. These fruits are often called "drupes" and examples include cherries, peaches, plums, and olives.

* Non-corniferous: Includes all trees that don't produce drupes. This category is broad and encompasses a wide variety of trees, including:

* Coniferous trees: These trees have cones instead of fruits, like pines, firs, and spruces.

* Deciduous trees: These trees lose their leaves in the fall, and many produce other types of fruits, like apples, pears, and acorns.

* Other trees: This group includes trees with various types of fruits or seeds, including walnuts, pecans, chestnuts, and many others.

In summary: The term "non-corniferous" simply means a tree that does *not* produce a specific type of fruit. To understand what kind of tree you're dealing with, you need to consider other characteristics like its leaf type (coniferous or deciduous), fruit type, and other identifying features.
