Compare with presumably bona fide Lomatium nudicaule a few feet away https://www.inaturalist.org/observations/219211540
Last photo shows several Lomatium nudicaule in foreground and this single plant in the background.
Taller, leaf larger and possibly thicker, stouter petiole, flower from leaf axil well above ground, secondary umbel upswept (possibly only from different floral stage) and with fewer flowers, slightly earlier flowering.
For convenience, a list of possible observations of this species in this general area (mostly based on appearing tall or robust, some are wild guesses):

Predated by Barred Owl.
Above ~7,100 ft in elevation
Not entirely sure how to tell the difference between S. audubonii and S. holzneri in this instance. But I am leaning toward holzneri based on elevation and my recollection that this rabbit struck me as moving a bit differently than other cottontails I saw on trail--like its back legs were oversized and their motion emphasized. Unfortunately, the lighting situation and my not-so-great photos make it difficult to differentiate according to nape color, not that I really could do that anyway...The shorter ears relative to the body and head size (at least in my estimation) also make me think holzneri, but I'm no rabbit expert, just a curious observer!
50/50 mixture of 1 and 2 needled bundles.
May be the species endemic to the Park but I don't have the key handy at this time.
Wikipedia, Kew's Plants of the World Online, and SEINet all recognize this variety as Cercocarpus breviflorus, which in iNat is currently an "Inactive Taxon"
UPDATE: iNat will make a taxon change to C breviflorus

Coastal canyon, San Luis Obispo County
A gray-green leaved shrub with smooth, mahogany-colored bark. Leaves are simple, ovate, alternate, and petiolate with smooth margins. Leaves and stems have fine, glandular hairs. Evergreen.
Acanthocephala thomasi, a frequent visitor this time of year. The head has structural reinforcement, illustrated in a previous specimen, presumably to provide mechanical strength for piercing agave.
The claretcup cactus can form large mounds covered with these trumpet shaped scarlet flowers. The cylindrical stems are densely spined. There are up to twelve spines per areole.
