Fritillaria biflora var. ineziana (Hillsborough chocolate lily) is a species of fritillary endemic to San Mateo County, California. It grows on serpentinite in cismontane woodland and valley and foothill grassland at elevations that range from 295 to 525 feet (90 to 160 meters) It is typically found on serpentine soils and it is defined as a "broad endemic" (5.4/6.2 affinity) where 85-94% of occurrences are expected to occur on ultramafic soils.

Fritillaria biflora var. ineziana is a perennial bulbiferous herb growing to a maximum height of 4 to 10 inches tall. The stem is stout and slender and bears 1-2 yellow-green, green-purple, or dark brown flowers that possess an unpleasant odor. The linear oblong leaves are often faintly mottled with yellow. The holotype specimen was collected by Inez Smith on Mar 12, 1914 and it is presently cataloged at the Jepson Herbarium (Specimen number JEPS4952). An isotype exists at the Rancho Santa Ana Botanic Garden Herbarium (Specimen number: RSA279408).
