How to identify Geranium core-core (Alderney crane's-bill)

This project collects observations of Geranium core-core (Alderney Crane's-Bill) in California for the purpose of facilitating identification and preventing misidentification of this species in iNaturalist.

Photo tips:

• It’s important to get a picture of the entire plant.
• It's also helpful to get close-up pictures of the face of the flowers, sepals, leaves, and fruits, if present.
• If there are multiple plants in the picture, it’s helpful to crop your photo to focus on the plant of interest.

How to identify Geranium core-core:

• Leaves: This plant has broad wedge-shaped leaves divided 55‒80 % to base. Leaves have 5‒7 segments.
• Flowers: The flowers have dark pink to purple petals that are broad and shallowly notched with yellow reproductive parts. Petals overlap each other. The sepals are smooth – there are no long hairs. Petals can have stripes, but they are usually fainter than most other species, though.
• Habitat: disturbed places.
• Flowering Time: March through October

Similar Species:

• Geranium dissectum (Cut-leaved Crane’s Bill)
• Geranium pusillum (Small-flowered Crane’s Bill)

How to differentiate G. core-core from G. dissectum:

• G. core-core has yellow reproductive parts; G. dissectum has purple reproductive parts and stripes on petals;
• G. core-core leaves are darker, wider, and have a more succulent texture; G. dissectum leaves appear thinner and lacier.
• G. core-core fruits are deeply keeled; G. dissectum fruits are shallowly keeled.
• G. core-core is much less common than G. dissectum.

How to differentiate G. core-core from G. pusillum:

• G. core-core flowers are a darker pink to purple and petals are broader and not so distinctly notched.
