Collinsia verna, or blue-eyed Mary, is a winter annual that is native to the eastern and central parts of North America but has become endangered in the states of New York and Tennessee. The flowers are bicolored white and blue. It is a plant of valley bottoms and moist bottom slopes, in areas with moderate lighting and requires some shade.
Collinsia verna is native to Ontario, New York, south to Virginia, southwest to Tennessee and Oklahoma, and north to Kansas, Iowa, and Wisconsin. It is also present in a multitude of other places filling the eastern states of the U.S. [2] [3]
Collinsia verna is often found in areas of damp open wood as it requires ample amounts of shade. Moist to mesic environmental conditions with rich loamy soil are preferred as the growth and size of individual plants is strongly influenced by the moisture conditions and the richness of the soil. The seeds need to be planted during the summer so that they will germinate during the fall. Collinsia verna can also flourish in habitats including wooded lower slopes of river valleys, and along woodland paths. Sometimes Blue-Eyed Mary grow in drier deciduous woodlands, however in these cases, the individual plants are reported to be smaller in size. [4] [5] [ self-published source? ]
Individual specimens can usually be found to be about 4-12 inches (10–30 cm) tall. Leaves opposite of each other can be up to 2" long and ¾" across; either medium green or yellowish green, and either glabrous or pubescent (usually the latter). The middle leaves are the largest, they range from being oval to broadly lanceolate, usually with a few blunt edges along their margins, and their bases are either sessile or clasp the stem. Sometimes individual flowers develop from the axils of the upper leaves; these axillary flowers have slender pedicels up to 1½" long. Each flower is ½-¾" across, consisting of a green calyx with 5 teeth and a blue/white corolla; the calyx is light green to purplish green. The corolla is divided into upper lip regions and lower lip regions. The upper lip is split into 2 large rounded lobes that are white, while the lower lip is slip into 3 lobes. The 2 large outer lobes of the lower lip are light blue to blue-violet, while the tiny middle lobe of the lower lip is folded into a keel and hidden from view. Its root system consists of a slender taproot. Collinsia verna is considered to be an herb. [5]
Collinsia verna reproduces via self pollination and through the late time of receptivity and change in position of its stigma and anther, resulting in delayed selfing. "In most flowers (70%), the stigma has moved to the front of the keel and is positioned near the anthers when the third anther dehisces. Under field conditions, fruiting success of plants within pollinator exclosures was; 75% of the fruiting success in open-pollinated plants (33% fruiting success via autogamy vs. 44% fruiting success, respectively)." (Susan Kalisz, 1999) It was concluded that autogamy indeed did occur late in floral development which raises its potential for reproductive assurance, and that individual flowers varied in their ability to set fruit through this mechanism.

Polemonium reptans is a perennial herbaceous plant native to eastern North America. Common names include spreading Jacob's ladder, creeping Jacob's ladder, false Jacob's ladder, abscess root, American Greek valerian, blue bells, stairway to heaven, and sweatroot.
Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower or at the ovule. There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm. Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma. The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other type of self-fertilization.

It is native to parts of Eurasia but has been introduced to North America. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.
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.

Collinsia corymbosa is a species of flowering plant in the plantain family known by the common name round-headed Chinese houses. It is endemic to the coastline of California north of the San Francisco Bay Area, where it is uncommon and scattered. Its habitat is the sand dunes of the immediate coastline. This is an annual herb producing a scaly, hairy, red to reddish green stem which grows upright or decumbent to a maximum length of about 25 centimeters. The thick, sparsely hairy leaves are rippled and lobed along the edges, which may be somewhat turned under. The inflorescence is a dense whorl of several distinctive flowers. Each has a hairy calyx of lobed reddish sepals and a corolla up to about 2 centimeters long. The flower has two small upper lobes and three longer lower lobes which come together in a nearly tubular shape. It is generally white with a light purple tint. The smaller upper lobes curl back and dry to brown at their lips.

Mimulus alatus, the sharpwing monkeyflower, is an herbaceous eudicot perennial that has no floral scent. It is native to North America and its blooming season is from June to September. The flowering plant has green foliage and blue to violet flowers. It has a short life span compared to most other plants and a rapid growth rate. Like other monkey-flowers of the genus Mimulus, M. alatus grows best in wet to moist conditions and has a bilabiate corolla, meaning it is two-lipped. The arrangement of the upper and lower lip petals suggests a monkey’s face. The winged stems together with the monkey face give the plant its common name.
Monopsis is a genus of small, Lobelia-like herbaceous plants indigenous to Africa. A few species are annuals, but most are perennials. Common names are not well established, but often refer to more familiar plants, as in "wild violet" for Monopsis unidentata, "yellow lobelia" for Monopsis lutea or "pansy lobelia" for Monopsis debilis.
In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
