Recent taxonomic treatments of the genus Harpagonella have included only one lower taxon, Harpagonella palmeri A. Gray. However, a larger-fruited variety of Harpagonella palmeri from Arizona and Sonora was described by I.M. Johnston in 1924. He continued to recognize this taxon - Harpagonella palmeri var. arizonica - in his treatment of the genus in Kearney and Peebles's Arizona Flora in 1960. ...

The methanolic extract of the whole plant of Echium glomeratum Poir. (Boraginaceae) has afforded five pyrrolizidine alkaloids, three that were (7S, 8R)-petranine (1), (7S, 8S)-petranine (2), and (7R, 8R)-petranine (3a) or (7R, 8S)-petranine (3b), comprising a tricyclic pyrrolizidine alkaloids subclass; and two that were known but to the species: 7-angeloylretronecine (4) and 9-angeloylretroneci...
