Summit of Laguna Mountain (San Benito County, California, US)family
Polemoniaceae
synonyms Gilia brecciarum ssp. jacens
notes Another detail of the leaves of a smaller plant form the population at the summit of Laguna Mountain. This photo was taken in the year preceeding the most others posted here, but at the same site. ______________________ [Update 4/12/17]: This post was previously placed under Gilia jacens...but over time it has become clear that these plants represent an undescribed taxon. A while back, Ryan O'Dell...BLM botanist with the Clear Creek Management Area...solicited opinions from the foremost authorities on CA Gilia (J. Mark Porter and Leigh Johnson) about the ID here and, while they saw how the post could end up at G. jacens when run through the available keys, their impression was that the plants were most likely an undescribed taxon with possible affinities to (but also conflicts with) G. ochroleuca bizonata, G. o. vivida, or G. latifolia cuyamensis. Ryan has been working to better understand these plants, and will hopefully succeed in finding knowledgeable collaborators with the expertise to clarify the situation, and eventually write up and publish a description for these plants, which appear to comprise a distinctive serpentine endemic taxon. ______________________ photo category: Plant - annual/perennial

| Reviewer's comments: | | | | "Gilia jacens "subsp. benitensis" O'Dell. In southern San Benito County, Gilia jacens occurs on marine shale, sandstone, greywacke, chert, serpentinite, and mixed alluvium (mostly serpentinite). Generally all on rock outcrops/barrens. Those on sandstone (sandy soil) are quite tall statured (erect) with bracts much reduced in size, and large, light blue corolla - tentatively placed as Gilia jacens "subsp. joaquinana" O'Dell. Those on bedrock serpentinite (Laguna Mtn, Hepsedam Peak) are very short statured with a low, ascending to decumbent infloresence, with large purple-blue corolla having yellow corolla tube streaks - tentatively placed as Gilia jacens "subsp. benitensis" O'Dell. Overall, there appears to be some isolation and speciation in Gilia jacens of southern San Benito County, western Fresno County, and eastern Monterey County. The morphological divergence patterns are consistent for sandstone ("subsp. joaquinana") and serpentinite of Laguna Mtn ("subsp. benitensis"), but generally not for other substrate types (typical "subsp. jacens") - marine shale, greywacke, chert, and mixed alluvium (mostly serpentinite). These typical "subsp. jacens" appear nearly identical to those from the Transverse Range (core species range). It is not entirely clear how many subspecies should possibly be recognized. Under study." |
