Uses (San Mateo County Parks prohibits removal of any natural material)

• Wildlife
  • Visited by native bees, flies, and hummingbirds (Burke 2024; Bressette)
  • Larval food source (host) for some butterflies and moths, i.e. wild forget-me-not moth (Gnophaela latipennis) and crambid snout moth (Udea itysalis)
• Native people
  • Grated roots used to treat stomach aches and venereal diseases, and as a dressing for burns
  • Roots cooked and eaten

Name Derivation

• Adelinia (a-de-LIN-ee-a) – named for Adeline Etta Cohen (2014- ) by her father, botanist Dr. James Cohen in 2015
• grandis (GRAN-dis) – from the Latin for “big” or “showy”
• Hound’s-tongue – for the shape of the large leaves
  • Some Native people called this plant “coyote ears” (Breckling 2008)

Notes

• Bees perceive ultraviolet colors of the nectar appendages, which appear white to us (Breckling 2008)
• Nutlets have hooks (cf. velcro) that catch on passing animals to aid in dispersal
• Scientific name changed in 2021 from Cynoglossum grande
  • This was an especially apt (and beloved) name as Cynoglossum came from the Greek for “dog’s tongue”

ID Tips

• May be confused with forget-me-nots (Myosotis species), which are non-native
  • Hound’s tongue has larger, wider leaves; its flower center is white
  • Forget-me-nots have much smaller, narrower leaves; their flower centers are yellow

At Edgewood

• Found in woodlands, especially in dappled shade
  • See iNaturalist for observations of this plant
• Flowers February – April
