Genera

[ Back to top ]

Androsace

Herbs perennial, annual, or biennial, acaulescent, rarely caulescent with ascending or decumbent shoots from a caudex. Leaves forming a rosette, rarely alternate; rosettes solitary or clustered, forming lax mats or compact cushions. Inflorescences umbellate, rarely a solitary flower, with bracts. Flowers 5-merous, homostylous. Calyx campanulate to subglobose, shallowly to deeply lobed. Corolla white, pink, purple, or dark red, rarely yellow; tube usually ± inflated, ca. as long as to shorter than calyx; throat constricted; lobes entire or emarginate. Stamens included, inserted on corolla tube; filaments very short; anthers ovate, apex obtuse. Style not longer than corolla tube. Capsule subglobose, dehiscing nearly to base. Seeds few to many.[1] [more]

Aneilema

Aneilema is a genus of in family Commelinaceae. It contains the following species (but this list may be incomplete): [more]

Campanula

Plants perennial or annual, erect trailing or decumbent, glabrous, pubescent, or hirsute. Leaves simple, alternate or forming rosettes at the base. Inflorescence 1-many flowered, with racemes or spikes. Flowers blue to purple or white. Sepals 5, with or without reflexed appendages between lobes; calyx tube adnate to the ovary, segments 5-lobed. Corolla campanulate, funnel-shaped or tubular. Stamens 5, free, filaments dilated at the base. Ovary 3-locular; style cylindrical; stigmas 3. Fruit a capsule, elongated to ovoid, obovoid or round, with membran¬ous walls; dehiscence by irregular pores at the bases or the sides. Seeds minute, numerous.[2] [more]

Caralluma

Succulent, perennial, branched herbs. Stem erect, branched, 4-angled, glabrous. Leaves small caducous. Flowers single or few or many-flowered sessile lateral cymes or many-flowered inflorescence from the top of the stem. Calyx 5-partite, lobes ovate to linear-lanceolate, Corolla purple or yellowish with purple streaks, rotate or broadly campanulate, 5-lobed, valvate in bud. Corona double, attached to the staminal column; the outer corona of 5 deeply bifid segments; the innner corona of 5 linear segments incumbent on the anthers. Staminal column short, arising from the base of the corolla; anthers without appendages. Pollen mass 1 in each anther cell, with a pellucid margin. Follicles 9-11 cm long, narrowly fusiform, smooth.[3] [more]

Castilleja

Herbs, annuals or perennials, rarely shrubs, hemiparasitic. Spikes or racemes terminal; bracts leaflike, often broader than leaves, variously colored, entire or lobed. Calyx tubular, base often gibbous abaxially, 2- or 4-lobed, median clefts usually deeper than lateral. Corolla tube included in calyx; limb conspicuously 2-lipped; lower lip short, patent, 3-lobed; upper lip elongated, rostrate apex entire. Stamens 4, didynamous; anthers enclosed by upper lip. Capsule loculicidal. Seeds numerous, minute; seed coat transparent, foveolate.[4] [more]

At least 579 species and subspecies belong to the Genus Castilleja.
