Hesperolinon Clevelandii
''Hesperolinon'' is a genus in the family Linaceae, whose common genus names are dwarf-flax or western flax, in reference to their distribution along the west coast of North America. There are 13 known species within this genus of wildflowers, most of which are limited to serpentine soil habitats within California, United States. Helen K. Sharsmith, 1961 ''Univ Calif Publ Bot'', 32:235–314 These annual plants are thought to be mostly self-pollinating. Description Stems vary between five and fifty centimeters in length, with thread-like to linear leaves generally alternate: the leaves are typically not planar and not clasping. Cymes are characteristically open and pedicels are somewhat thread-like and ascending. The flower has five sepals, whose margins may be minutely gland-toothed. Five petals are widely spreading between one and twelve millimeters in dimension. These yellow, white or rose colored petals each manifest three minute scales at the inner base. There are fi ...

Ovary (plants)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...

Hesperolinon Serpentinum
''Hesperolinon serpentinum'' is a rare species of flowering plant in the flax family known by the common name Napa dwarf flax, or Napa western flax. ''Hesperolinon serpentinum'' was not validly published by McCarten although it appears in the Jepson Manual (Hickman, 1993). The species was validly published as ''Hesperolinon sharsmithae'' in 2006 by O'Donnell (Madroño 53:404–408). The species is endemic to northern California, where it is known from fewer than twenty occurrences in four counties surrounding the San Francisco Bay Area. It is a member of chaparral plant communities, generally on serpentine soils. It produces a thin, erect stem up to 30 centimeters tall, with sparse flat, narrow leaves.

Hesperolinon Congestum
''Hesperolinon congestum'', or Marin dwarf flax, is an annual herb, which is known to occur only in San Mateo, San Francisco and Marin County, California, United States. This plant occurs chiefly on serpentine soils, especially in dry native bunch grasses, chaparral or other grasslands at elevations less than 200 meters. The flowers are congested at the tips of the dichotomously branching stems. ''H. congestum'' is in flower between April and July. The outlook for this plant depends on survival of only about twenty small colonies, most of which are not actively managed for protection, even though the species is federally and state-listed as threatened. This species is also less commonly known as Marin western flax. Description Stems of this wildflower vary between five and fifteen centimeters in length, with linear leaves manifesting alternately. The leaves are typically not planar and not clasping, and stipule glands are well developed with red exudate. Inflorescences a ...
