Reproductive biology and nectar secretion dynamics of Penstemon gentianoides (Plantaginaceae): a perennial herb with a mixed pollination system?
Salas-Arcos L, Lara C, Ornelas JF. Salas-Arcos L, et al. PeerJ. 2017 Aug 9;5:e3636. doi: 10.7717/peerj.3636. eCollection 2017. PeerJ. 2017. PMID: 28828248 Free PMC article.
We aimed to investigate floral traits linked to this pollination syndrome in Penstemon gentianoides with flowers visited by bumblebees and hummingbirds. METHODS: We investigated the floral biology, pollinator assemblages, breeding system and nectar production patterns of P …

Pensteminoside, an unusual catalpol-type iridoid from Penstemon gentianoides HBK (Plantaginaceae).
Domínguez M, Marín JC, Esquivel B, Céspedes CL. Domínguez M, et al. Phytochemistry. 2007 Jul;68(13):1762-6. doi: 10.1016/j.phytochem.2007.03.035. Epub 2007 May 15. Phytochemistry. 2007. PMID: 17507063
From the MeOH and ethyl acetate extracts of aerial parts of Penstemon gentianoides HBK (Plantaginaceae) an unusual iridoid of the catalpol-type, was isolated and characterized as pensteminoside: (8-O-trans-cinnamoyl, 6-hydroxy, 1-[beta-D-glucopyranoside-6'-O-((4''-hydroxy) …

"Pro-bird" floral traits discourage bumblebee visits to Penstemon gentianoides (Plantaginaceae), a mixed-pollinated herb.
Del Carmen Salas-Arcos L, Lara C, Castillo-Guevara C, Cuautle M, Ornelas JF. Del Carmen Salas-Arcos L, et al. Naturwissenschaften. 2018 Dec 17;106(1-2):1. doi: 10.1007/s00114-018-1595-4. Naturwissenschaften. 2018. PMID: 30560485
Here, we modified bee-pollination floral traits in Penstemon gentianoides with a mixed pollination system, to resemble hummingbird-pollination traits, and measured the effects of trait modification on bumblebee foraging behavior and plant female reproductive fitness. ...
