Porterella
''Porterella'' is a monotypic genus of flowering plants in the bellflower family containing the single species ''Porterella carnosula'', which is known by the common name fleshy porterella, or simply porterella. The species is native to the western United States from California to Wyoming, where it grows in moist spots, such as ponds or wet grasslands, sometimes just at the edge of the water or partially submerged. It is an annual herb producing an erect stem to a maximum height around 30 centimeters. The leaves along the stem are oval or triangular, those growing beneath the surface of the water more triangular in shape. They measure up to 1.5 centimeters long by half a centimeter wide. The inflorescence bears showy flowers which are quite similar in appearance to those of some species in sister genus '' Downingia''. Each has a narrow tubular throat opening into a wide corolla with two narrow pointed upper lobes and three wider, rounded lower lobes each with a small tooth. The u ...

Campanulaceae
The family Campanulaceae (also bellflower family), of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. Among them are several familiar garden plants belonging to the genera '' Campanula'' (bellflower), ''Lobelia'', and ''Platycodon'' (balloonflower). ''Campanula rapunculus'' (rampion or r. bellflower) and ''Codonopsis lanceolata'' are eaten as vegetables. ''Lobelia inflata'' (indian tobacco), '' L. siphilitica'' and '' L. tupa'' (devil's tobacco) and others have been used as medicinal plants. ''Campanula rapunculoides'' (creeping bellflower) may be a troublesome weed, particularly in gardens, while ''Legousia'' spp. may occur in arable fields. Most current classifications include the segregate family Lobeliaceae in Campanulaceae as subfamily Lobelioideae. A third subfamily, Cyphioideae, includes the genus ''Cyphia'', and sometimes also the genera ''Cyphocarpus'', ''Nemacladus'', ''Parishell ...

Thomas Conrad Porter
Thomas Conrad Porter (1822–1901) was an American botanist and theologian known as an expert on the flora of Pennsylvania. Biography Porter was born in Alexandria, Pennsylvania on January 22, 1822. He attended Harrisburg Academy before enrolling in Lafayette College at the age of 14. He graduated in 1840, and returned home to Alexandria and began to collect plants near Tussey Mountain. He went on to attend Princeton Theological Seminary, graduating in 1844. He moved down to Monticello, Georgia for a year as part of a Presbyterian mission. Here he collected at places such as Stone Mountain and Toccoa Falls, and began collaborating with Asa Gray. He discovered '' Gymnolomia porteri'' during his time at Stone Mountain. In 1849, Porter was brought on as a professor of natural sciences at Marshall College. He stayed at the institution until 1866.

Lobelioideae
Lobelioideae is a subfamily of the plant family Campanulaceae. It contains 32 genera, totalling about 1200 species. Some of the larger genera are ''Lobelia'', ''Siphocampylus'', ''Centropogon'', ''Burmeistera'' and '' Cyanea''. They are perennials, sometimes annuals, ranging in form from herbs to small trees. Most species are tropical in distribution, but in total this subfamily occurs almost worldwide, being absent only from Arctic regions, central Asia and the Near East. The subfamily is particularly diverse in Hawaii, where well over 100 species of Hawaiian lobelioids have radiated from a single introduction. This subfamily was formerly given family rank as Lobeliaceae, under a somewhat different circumscription. The leaves are simple and alternate. The plants have milky sap. The flowers are bilaterally symmetric with five lobes and stamen The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens fo ...

William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the supportive friendshi ...

John Torrey
John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician. Throughout much of his career, he was a teacher of chemistry, often at multiple universities, while he also pursued botanical work, focusing on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, and the uncompleted ''Flora of North America''.

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Downingia
''Downingia'' is a genus of 13 annual plants native to western North America and Chile. Commonly known as calico flowers, they are notable for forming mass displays of small but colorful blooms around vernal pool Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe ...s. A number are uncommon endemics in California. The stems may be decumbent or erect, 10–40 cm in length, with narrow cauline leaves that may drop off before the flower develops. The flowers are typically inverted by the twisting of the ovary during blooming. Colors range from blue and pink to white, with the lower (larger) lip including a white or yellow patch. The lower lip generally consists of three lobes, while the upper lip is much smaller and has two lobes. The genus is named after American horticulturalist ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...
