Question: Are Melastoma and Barringtonia both types of flowers?
Context: Melastoma is a genus in the family Melastomataceae.  It has about 50 species distributed around Southeast Asia, India, and Australia.  It is undergoing taxonomic revision.  Many species have been planted around the world for the aesthetic value of their bright purple flowers.  Several have the capacity to become weedy, and have become noxious weeds in Hawaii and other areas. Streptanthella is a monotypic genus of flowering plants in the mustard family containing the single species Streptanthella longirostris, which is known by the common name longbeak streptanthella, or simply streptanthella.  It is native to western North America, where it occurs throughout the western United States and the northwestern states of Mexico.  It grows in many types of habitat, including deserts, sagebrush, foothill woodlands, sandy flats, chaparral, and scrubby canyons.  It is an annual herb producing a slender, erect, multibranched stem up to half a meter tall.  The lower leaves are lance-shaped with a toothed or smooth edge and leaves higher on the plant are narrower, linear in shape, and less often toothed.  The top of the stem is occupied by a long inflorescence which is an open raceme of many flowers.  The top of the inflorescence bears the newest buds which are often purple in color.  More mature flowers stud the stem at intervals below, each on a short pedicel.  Flowers measure under a centimeter long.  Each flower is enclosed in four thick sepals.  At the tip are the spoon-shaped petals which are white to yellow with purple veining.  The fruit is a long, dangling silique up to 7 centimeters in length containing flat, winged seeds. Barringtonia longisepala grows as a tree up to 21 m tall, with a trunk diameter of up to 35 cm .  Bark is dark grey or greyish brown.  Flowers are yellow.  Fruit is oblong, up to 14 cm long.  Habitat is hillside and swamp forests.  "B. longisepala" is endemic to Borneo. Silene menziesii is a species of flowering plant in the pink family known by the common names Menzies' campion and Menzies' catchfly.  It is native to western North America from Alaska through the western half of Canada to the southwestern United States.  It can be found in many types of habitat and it is quite common in much of its range.  It is variable in morphology and there are a number of varied subtaxa.  In general, it is a perennial herb growing from a caudex, appearing matlike, decumbent, or erect, with stems a few centimeters to over half a meter long.  It is usually hairy in texture, with upper parts bearing sticky glandular hairs.  The leaves are lance-shaped, oppositely arranged in pairs, and a few centimeters in length, upper leaves usually smaller than lower.  Flowers may occur in a cyme at the top of the stem, or in leaf axils, or both.  Each is encapsulated in a hairy, veined calyx of fused sepals.  The petals are white with two lobes at the tips.  The plant is dioecious with male and female plants producing different flowers.  The male and female flower types look the same externally; the stamens are reduced in female plants and the stigmas are reduced in the male. Pelargonium × hortorum, (also called zonal geranium, garden geranium, malva or malvón), is a nothospecies of "Pelargonium" most commonly used as an ornamental plant.  It is a hybrid between "Pelargonium zonale" and "Pelargonium inquinans".  Availability includes the usual nursery "seed-grown" and the "cutting grown" types, which can easily be propagated at home by cutting and planting side branches.  These are stocky and large.  The flowers can be single or double.  The leaves are often fragrant.  The flowers come in many colors, including red, shades of pink and white.  Recently, orange and yellow cultivars have been developed.  Many cultivars have been grown since the late eighteenth century.  Cultivars with very double flowers and no anthers are called Rosebud Pelargoniums since the flowers never open completely and therefore resemble a rosebud. In biology, gonochorism ("Greek" offspring + disperse) or unisexualism or gonochory describes the state of having just one of at least two distinct sexes in any one individual organism.  The term is most often used with animals, in which the individual organisms are often gonochorous.  Gonochory is less common in plants.  For example, in flowering plants, individual flowers may be hermaphrodite (i.e. with both stamens and ovaries) or gonochorous (unisexual), having either no stamens (i.e. no male parts) or no ovaries (i.e. no female parts).  Among flowering plant species that have unisexual flowers, some also produce hermaphrodite flowers, and the three types occur in different arrangements on separate plants; the plants can be monoecious, dioecious, polygamomonoecious, polygamodioecious, andromonoecious, or gynomonoecious. Barringtonia is a genus of flowering plants in the family Lecythidaceae first described as a genus with this name in 1775.  It is native to Africa, southern Asia, Australia, and various islands of the Pacific and Indian Oceans.  The genus name commemorates Daines Barrington. Carex alma is a species of sedge known by the common name sturdy sedge.  It is native to the southwestern United States and northern Mexico, where it grows in moist spots in a number of habitat types.  This sedge forms a thick clump of thin stems up to 90 centimeters in length and long, thready leaves.  The leaves have basal sheaths with conspicuous red coloration, often spotting.  The inflorescence is a dense to open cluster of many spikelets occurring both at the ends of stems and at nodes.  Each cluster is up to 15 centimeters long and 1 to 2 wide.  The plant is sometimes dioecious, with an individual sedge bearing either male or female flowers.  The female, pistillate flowers have white or white-edged bracts.  The male, staminate flowers have visible anthers 2 millimeters long or longer.  The fruit is coated in a sac called a perigynium which is gold to dark brown in color and has a characteristic bit of spongy tissue at the base. Hanakotoba (花言葉 ) is the Japanese form of the language of flowers.  In this practice, plants were given codes and passwords.  Physiological effects and action under the color of the flowers, put into words from the impressions of nature and the presence of thorns with the height of tall plants, flowers and garlands of flowers through the various types.  These are meant to convey emotion and communicate directly to the recipient or viewer without needing the use of words. "Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers.  The double-flowered trait is often noted alongside the scientific name with the abbreviation "fl.  pl."  (flore pleno, a Latin ablative form meaning "with full flower").  The first abnormality to be documented in flowers, double flowers are popular varieties of many commercial flower types, including roses, camellias and carnations.  In some double-flowered varieties all of the reproductive organs are converted to petals — as a result, they are sexually sterile and must be propagated through cuttings.  Many double-flowered plants have little wildlife value as access to the nectaries is typically blocked by the mutation.
