Is this the forum category for discussion about taxonomic keys?
As far as any key to the plant Genus Lupinus, or in general, when discussing the traits of Lupine flowers, there are some details to consider, of course.
Let’s discuss using a key to Lupinus, and any challenges we may encounter.
For example, in reference to the lobes of a keel existing or not, are you confident with this observation detail? Do you have photos of a Lupine keel that has lobes and one that doesn’t?
Help me understand exactly what it looks like when not lobed. A link to an observation would be great for this.
