The etymology of the word "Penstemon Dolius" can be broken down as follows:
1. Penstemon: The word "Penstemon" is derived from the Greek words "penta", meaning "five", and "stemon", meaning "stamen" (the male reproductive organ of a flower). This name was given to the plant because its flowers typically have five stamens, which is a characteristic of the Penstemon genus.
2. Dolius: The word "Dolius" is derived from Latin and refers to a mythological character in Greek mythology. Dolius was a loyal servant of Odysseus and played a role in the epic poem "The Odyssey" by Homer. It is unclear why this specific name was chosen for the Penstemon species, as it might be related to its growth habit, appearance, or perhaps a personal connection of the botanical namer.
