The focus of this observation is not the plant (Plantago lanceolata), but whatever is causing the malformation. Instead of an inflorecense developing it seems to be producing a rosette of leaves and a white feathery looking texture at the base of those leaves.

Description

(Arceuthobium littorum) Coastal Dwarf-Mistletoe is a Native parasitic mistletoe that only grows on native Monterey Pine and Bishop Pine; endemic to the coastline of northern California where these trees grow. Main stem is 3--14 cm, with segmented offshoots that are yellowish brown to olive green, with fragile, jointed stems. Only a tiny part of the plant is visible; most is parasitizing beneath the bark. Parasitic specifically on Pinus radiata (Monterey Pine) and Pinus muricata (Bishop Pine). Peak bloom time:
July-November. Fruits are clusters of pale green, spherical-shaped balls in the fall. An example observation of fruiting: https://www.inaturalist.org/observations/93928981

See Fred Watson Journal Post discussion of Arceuthobium littorum vrs A. campylopodum: https://www.inaturalist.org/journal/fredwatson/69693-coastal-dwarf-mistletoe-arceuthobium-littorum-taxonomic-history

TREATMENT FROM THE JEPSON MANUAL (1993)
https://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment?7836,7837,7845

A search on Jepson's eFlora of Arceuthobium littorum-- Jepson calls it a "synonym" and takes you to A. campylopodum. https://ucjeps.berkeley.edu/eflora/eflora_display.php?tid=13881

These 3 local references call it Arceuthobium littorum, Coastal Pine Dwarf Mistletoe:

Arceuthobium littorum (Pine/Dwarf Mistletoe) "Habitat: Coastal. This species is found only near the coast, on Monterey and Bishop Pines (Pinus radiata and Pinus muricata). It is wholly parasitic, using specially modified roots called haustoria to draw water and nutrients from its host plant. Although Jepson combines this species with two others under Arceuthobium campylodum, more recent literature suggests that differences in form and host plants justify keeping the three species separate."

This seems to be a braconid wasp not known to be a gall former... so it must have tagged along somehow. They are known to parasitize lepidopterans so there could have been some micromoth pupa or larva on the foliage that I did not see?

Michael's Rein Orchid (Platanthera michaelii) Native orchid, endemic in California, growing in Maritime Chaparral habitat. Basal leaves wither and disappear before plant sends up a stalk. Flowers/perianth is green to yellow-green. Lowest petal lip is broad/deltate-ovate. The 2 lower sepals spread outward (and are not reflexed like P. elongata). The 3 upper sepals/petals are concave and point upward. Spur is long at 8-12 mm (but not as long as P. elongata whose spur is 6.5-18 mm). Peak bloom time: June-July.

Piperia is a former genus within the orchid family Orchidaceae that has since been subsumed under Platanthera. Jepson eFlora and all the references below still call it Piperia michaelii, Michael's Rein Orchid
