Frequently Asked Questions About Identification


You were unable to identify the leaf I submitted for identification. Why?
Leaf Sample
The sample probably did not consist of sufficient material for identification. Samples should consist of representative parts of the plant (roots, stems, leaves, and flowers) as well as complete background information about where and how the plant grows.

Floral morphology is the feature on which plant taxonomy and thus identification is based- without flowers we are often unable to identify the plant.


How can I find out what variety of apple is growing in my backyard?
We are typically unable to aid with identification of fruit varieties (or varieties of other landscape plants). The sheer number of varieties grown for plants such as apples, cherries, and rhododendrons can be staggering.


Are these mushrooms edible?
Mushroom Sample
We have no trained mycologist on staff at the WSU Puyallup Plant and Insect Diagnostic Laboratory so we are unable to identify mushrooms to species.

Nor, can we comment on the edibility of mushroom species as an individual's response to a mushroom can vary and confusion of edible mushrooms with toxic mushrooms could occur on a later picking.
