Genera

[ Back to top ]

Amsinckia

A fiddleneck is a flowering plant in the genus Amsinckia. The name derives from the flower stems, bearing many small flowers, which curl over at the top in a manner reminiscent of the head of a fiddle. Fiddlenecks are in the family Boraginaceae, along with borage and forget-me-nots. [more]

Asperugo

The German Madwort (Asperugo procumbens) is the single species in the monotypic plant genus Asperugo. This plant is native to Europe but has been introduced elsewhere, such as the northern half of North America. [more]

Cryptantha

Cryptantha is a genus of hairy plants in the borage family (Boraginaceae). Some of them are heterostylous. [more]

Eritrichium

Plants perennial or annual, appressed strigose or villous. Leaves alternate. Cymes terminal, not branched or branched and paniculate, rarely 1-flowered. Fruiting pedicel erect or deflexed. Calyx 5-parted to base or nearly so; lobes vertical to reflexed, enlarged in fruit. Corolla blue, light blue, or light purple, rarely yellow or white, campanulate-rotate to campanulate-tubular; throat with appendages, rarely appendages obscure or absent; lobes overlapping in bud, erect or divaricate at anthesis. Stamens included; anthers orbicular, ovate to oblong. Style and stigma solitary, usually not exceeding nutlets. Gynobase flattened-fastigiate or semiglobose to 1 mm, wider than tall at base. Nutlets 4, all or some developed, turbinate to ovoid or triangular-ovoid and dorsiventrally compressed; abaxially usually discoid, ribs or margin usually winged, dentate or with glochids.[1] [more]

Hackelia

Hackelia (Stickseeds) is a genus of plants in the Borage Family, Boraginaceae. They are found in North America and southeast Asia. Of the approximately 40 species described, 10 are endemic to California. [more]

Lappula

Plants annual or biennial, rarely perennial, pilose, strigose, rarely sericeous throughout, hairs tuberclelike or discoid at base. Leaves alternate. Inflorescence a drepanium, elongated after anthesis, bracteate. Calyx 5-parted nearly to base; lobes frequently enlarged in fruit. Corolla light blue, rarely white, campanulate or low salverform; tube short; throat appendages 5, trapeziform; limb 5-parted. Stamens included. Ovary globose, 4-parted. Style not exserted; stigma capitate. Gynobase subulate veined, ca. as long as or surpassing nutlets, rarely shorter. Nutlets 4, adherent to gynobase by entire adaxial rib or only by rib base, erect, homomorphic or heteromorphic; margin of abaxial surface usually with 1(-3) rows of glochids; bases of glochids separated or contiguous or confluent into a wing, rarely reduced to tubercles.[2] [more]

Mertensia

Mertensia is a genus of plants belonging to the family Boraginaceae. There are about 40 species in the genus. This is one of several different plants that are commonly called Bluebell. [more]

Plagiobothrys

Plagiobothrys is a genus of flowering plants known commonly as popcornflowers. These are small herbaceous plants which bear tiny white or yellow flowers. Their fruits are . These plants are found in western North and South America. Of the approximately 65 species described, more than 15 are endemic to California. [more]

Rochelia

Herbs annual. Stems branched or simple, slender, hispid. Leaves alternate, 1-veined. Cymes scorpioid; bracts ± opposite flowers. Flowers pedicellate. Calyx 5-parted to base; lobes linear to lanceolate, somewhat enlarged in fruit, apex usually incurved, rarely straight. Corolla funnelform, light blue; tube straight or slightly curved; throat appendaged; limb 5-parted. Stamens inserted at lower part of corolla tube, included; filaments short; anthers oblong, apex with somewhat prominent connectives. Ovary divided; ovules 2. Style entire; stigma capitate. Gynobase subulate. Nutlets 2, each containing 1 seed, tuberculate, with glochids or glabrous; attachment scar near base.[3] [more]

Trigonotis

Herbs perennial, biennial, or rarely annual. Stems single or several and cespitose, erect to diffuse, hispid or pilose, rarely glabrous. Cymes solitary or dichotomously branched, ebracteate or lower pedicels bracteate, rarely all bracteate (flowers extra-axillary). Calyx 5-lobed or 5-parted, not enlarged or slightly enlarged in fruit. Corolla blue or white; tube usually shorter than calyx; throat appendages 4, lunate or trapeziform; lobes 5, spreading, overlapping. Stamens included; anthers oblong to elliptic. Ovary 4-parted. Style linear, usually shorter than corolla tube; stigma included, capitate. Gynobase flat. Nutlets 4, semiglobose-tetrahedral or subulate trigonous-tetrahedral, shiny, glabrous or pubescent, rarely tuberculate, adaxial 3 surfaces subequal in size or bottom smaller than 2 lateral surfaces, longitudinal vein at juncture of 2 lateral surfaces, sessile or with a short carpophore from corner of 3 adaxial surfaces, abaxial surfaces flattened or convex, acute or obtuse ribbed, rarely narrow winged; attachment scar at bottom of carpophore or at corner of 3 adaxial surfaces when sessile. Embryo vertical; cotyledon ovate.[4] [more]

At least 72 species and subspecies belong to the Genus Trigonotis.
