Note: this key assumes mature plants, with mature perigynia. It is best to use the “average” characteristics from a population, rather than using only those characteristics from a single plant. For example, some plants in a population may have multiple staminate spikes but your particular specimen has only one.

When in doubt, leave the setting to “any” and only set those characteristics you can say with some confidence are true or false. Good luck. :-)
