Babiana is a genus of geophytes in the family Iridaceae with 93 recognized species as of March 2022. The leaves consist of a stalk and a blade that are at an angle to each other. The leaf blades are entire, laterally flattened and pleated, and often hairy. Each individual flower is subtended by two hairy or smooth bracts that are green in most species. The outer bract is often the largest of the two. In most species the bracts have a dry, brown tip, but in a few species it is entirely green or entirely dry when flowering or the outer bract is translucent and has a papery texture. The inner bract is forked or split all the way to its base. Each flower is without a pedicel, with six tepals that are merged at their base into a tube and form a perianth that is mirror-symmetrical in most species, with three anthers implanted where the perianth tube widens and that are, in almost every species, clustered at one side of the style. The style has three branches that widen towards the tip and the ovary is inferior. Flowers occur in almost every conceivable colour, many have markings on some of the tepals, and few star-symmetrical flowers have a centre that strongly contrasts with the free part of the perianth. The majority of these species are endemic to the west and southwest of South Africa, and southwestern Namibia, but one species occurs elsewhere in Namibia and South Africa and another species can be found in Botswana, Namibia, South Africa, Zambia and Zimbabwe. The genus name is derived from the Dutch word baviaan, referring to the Chacma baboon, Papio ursinus, that consumes the corms of plants in the genus. The genus is called bobbejaantjie in Afrikaans, meaning small baboon.
Ixerba brexioides, the sole species in the genus Ixerba, is a bushy tree with thick, narrow, serrated, dark green leaves and panicles of white flowers with a green heart. The fruit is a green capsule that splits open to reveal the black seeds partly covered with a fleshy scarlet aril against the white inside of the fruit. Ixerba is an endemic of the northern half of the North Island of New Zealand. Common names used in New Zealand are tawari for the tree and whakou when in flower. It is assigned to the family Strasburgeriaceae.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.

There are 8 stamens with anthers bearing blue-gray pollen, and a protruding stigma.
Clarkia delicata is a rare species of flowering plant in the evening primrose family known by the common names Campo clarkia and delicate clarkia. It is native to northern Baja California and adjacent San Diego County, California, where it grows in the woodland and chaparral of the Peninsular Ranges. This is an annual herb producing an erect stem just over half a meter in maximum height. The leaves are oval or widely lance-shaped, up to 4 centimeters long, and borne on very short petioles. The top of the stem is occupied by the inflorescence, in which the lower flowers open while the upper buds hang closed. The sepals remain fused as the flower blooms from one side. Each unlobed oval petal is about a centimeter long and pink to pinkish-lavender. There are 8 stamens, some with large orange anthers and some with smaller, paler anthers. There is also a protruding stigma with four large, fuzzy lobes.
Clarkia dudleyana is a species of flowering plant in the evening primrose family known by the common name Dudley's clarkia. It is endemic to California, where it can be found in the mountains of the Transverse Ranges and the southern Sierra Nevada foothills. It grows in woodland, forest, and chaparral habitats under 1500 meters in elevation. This annual herb produces an erect stem sometimes exceeding half a meter in height. The leaves are lance-shaped, up to 7 centimeters long, and borne on short petioles. The top of the stem is occupied by the inflorescence, which has opening flowers below closed, hanging buds. As the flower blooms the pink to reddish-purple sepals remain fused, opening along one side only. The petals are up to 3 centimeters long, fan-shaped, pinkish lavender in color and sometimes flecked with red. There are 8 stamens, some of which have large lavender anthers and some that have smaller, paler anthers. The stigma protrudes farther than the stamens.
Clarkia exilis is a small herbaceous annual plant of western North America. It is an uncommon species in the evening primrose family known by the common names Kern River clarkia and slender clarkia.
Clarkia heterandra is a species of flowering plant in the family Onagraceae known by the common name mountain clarkia. It is endemic to California, where it is from the forests and woodlands of several of eastern and western mountain ranges. It is an annual herb producing an erect, glandular stem to around half a meter in maximum height. The lance-shaped to oval leaves are up to 8 centimeters long and are borne on petioles of up to 2 centimeters. The top of the stem is occupied by the inflorescence, with open flowers and closed buds. The sepals remain fused as the flower blooms from one side. The pink petals are oval in shape and just a few millimeters long. There are 8 stamens, some large and some small and sterile. The fruit is a small, hard body 2 or 3 millimeters long containing 1 or 2 seeds.

Dilatris is a genus of four species of evergreen perennial herbaceous plants of up to 60 cm (2.0 ft) high, that are assigned to the bloodroot family. The plants have hairless, line- to lance-shaped leaves set in a fan that emerges from a red or orange coloured rootstock. Six free tepals with some gland dots near their tips are present on the mauve or dirty yellow flowers' six free petals. The other two stamens are longer and spreading with smaller scarlet anthers, while the one stamen is short, upright, and has a large, yellow anther. The style is diverted from the centre opposite both longer stamens. The species only occur in the Western Cape and Northern Cape provinces of South Africa.
