Question: Are both the Sparganium and Portulaca considered "Flowering" plants?

Context paragraphs:
Portulacaceae: The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus "Portulaca".  Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere.  The family has been recognised by most taxonomists, and is also known as the purslane family; it has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions.  The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals.

Sparganium emersum: Sparganium emersum is a species of flowering plant in the cat-tail family known by the common names European bur-reed and unbranched bur-reed.  It has a circumboreal distribution, occurring throughout the northern latitudes of Eurasia and North America.  It is an aquatic plant, growing in shallow water bodies such as ponds and streams.  It can become abundant at times.  It is a perennial herb producing a floating stem up to 2 meters long.  The leaves may be limp and floating or stiff and erect, emerging above the water surface.  The leaves are flat and straplike, sometimes with a triangular, keeled base that can help distinguish it from the similar "Sparganium angustifolium".  It is monoecious, individual plants bearing both male and female inflorescences.  These are spherical, the male inflorescence a ball of stamens and the female inflorescence a ball of developing fruits growing beneath the male spheres.

Eudicots: The eudicots, Eudicotidae or eudicotyledons are a monophyletic clade of flowering plants that had been called tricolpates or non-magnoliid dicots by previous authors.  The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots.  The close relationships among flowering plants with tricolpate pollen grains was initially seen in morphological studies of shared derived characters.  These plants have a distinct trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis.  Later molecular evidence confirmed the genetic basis for the evolutionary relationships among flowering plants with tricolpate pollen grains and dicotyledonous traits.  The term means "true dicotyledons", as it contains the majority of plants that have been considered dicots and have characteristics of the dicots.  The term "eudicots" has subsequently been widely adopted in botany to refer to one of the two largest clades of angiosperms (constituting over 70% of the angiosperm species), monocots being the other.  The remaining angiosperms include magnoliids and what are sometimes referred to as basal angiosperms or paleodicots, but these terms have not been widely or consistently adopted, as they do not refer to a monophyletic group.

Canarina: Canarina is a genus of flowering plants within the family Campanulaceae.  They are herbaceous perennial vines with bell-shaped flowers.  The best known species is "C. canariensis" from the laurel forests of the Canary Islands which is grown as an ornamental plant.  "Canarina canariensis" is one of a group of unrelated Canarian plants that appear to be adapted for bird pollination, including the members of the genera "Isoplexis" and "Lotus".  It was once thought that the original pollinators of these plants were sunbirds which had become extinct on the Canary Islands, explaining why some of these species are rare and considered endangered (Vogel 1954; Vogel et al. 1984; Olesen 1985; Valido et al. 2004).  However more recent work has shown that these plants are adequately pollinated by non-specialist flower visiting birds, particularly the Canary Islands chiffchaff ("Phylloscopus canariensis") and the Canary Island spectacled warbler ("Sylvia conspicillata orbitalis") (Olesen 1985; Ollerton et al. 2008), and in fact show some specific adaptations to infrequent pollination by these birds, such as extended flower lifespans (Ollerton et al. 2008), and a hexose-dominated sugar ratio of the nectar (Dupont et al. 2004).

Portulaca: Portulaca ( , purslane) is the type genus of the flowering plant family Portulacaceae, comprising about 40-100 species found in the tropics and warm temperate regions.  They are also known as moss roses.

Carduus: Carduus is a genus of flowering plants in the aster family, Asteraceae, and the tribe Cynareae, one of two genera considered to be true thistles, the other being "Cirsium".  Plants of the genus are known commonly as plumeless thistles.  They are native to Eurasia and Africa, and several are known elsewhere as introduced species.  This genus is noted for its disproportionately high number of noxious weeds compared to other flowering plant genera.

Thigmotropism: Thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus.  Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.  This behavior occurs due to unilateral growth inhibition.  That is, the growth rate on the side of the stem which is being touched is slower than on the side opposite the touch.  The resultant growth pattern is to attach and sometimes curl around the object which is touching the plant.  However, flowering plants have also been observed to move or grow their sex organs toward a pollinator that lands on the flower, as in "Portulaca grandiflora."

Sparganium: Sparganium (bur-reed) is a genus of flowering plants, described as a genus by Linnaeus in 1753.  It is widespread in wet areas in temperate regions of both the Northern and Southern Hemispheres.  The plants are perennial marsh plants that can grow to 3.5 m (depending on the species), with epicene flowers.

Sparganium angustifolium: Sparganium angustifolium is a species of flowering plant in the cat-tail family known by the common names floating bur-reed and narrowleaf bur-reed.  It has a circumboreal distribution, occurring throughout the northern latitudes of the Northern Hemisphere.  It is an aquatic plant, growing in water up to 2.5 meters deep.  Its habitat includes acidic, low-nutrient freshwater bodies such as ponds, lakes, slow-moving streams, and ditches.  It can become abundant, practically covering the surface of the water.  It is a perennial herb producing a floating stem with long, narrow, flattened leaves which can be quite long, sometimes reaching over two meters.  It is monoecious, individual plants bearing both male and female inflorescences.  These are spherical, the male inflorescence a ball of stamens and the female inflorescence a ball of developing fruits.

Trilliaceae: Trilliaceae is the botanical name of a family of flowering plants.  The family has been recognised as distinct since 1846 when it was recognized; this table  for a summarizes the placement of these taxa.  The family has been recognized by taxonomists such as Takhtajan, Dahlgren, Thorne, and Watson & Dallwitz; other taxonomists have considered these plants to belong to the family Liliaceae.  The APG II system, of 2003 (unchanged from the APG system, of 1998), does not recognize such a family either and assigns the plants involved to family Melanthiaceae.  One problem with this recognition is the lack of morphological synapomorphies for the family Melanthiaceae; this chart  provides a summary of the characters in each of the major groups.
