literally "nose-twister" or "nose-tweaker"), is a genus of roughly 80 species of annual and perennial herbaceous flowering plants.
 It was named by Carl Linnaeus in his book "Species Plantarum", and is the only genus in the family Tropaeolaceae.
 The nasturtiums received their common name because they produce an oil similar to that of watercress ("Nasturtium officinale").
Pterostylis alveata, commonly known as the coastal greenhood, is a species of orchid endemic to south-eastern Australia.
 As with similar greenhoods, the flowering plants differ from those which are not flowering.
 In this species, the non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single small, shiny green and white flower with leaves on the flowering spike.
Ferula (from Latin "ferula", "rod") is a genus of about 170 species of flowering plants in the carrot family, native to the Mediterranean region east to central Asia, mostly growing in arid climates.
 They are herbaceous perennial plants growing to 1–4 m tall, with stout, hollow, somewhat succulent stems.
 The leaves are tripinnate or even more finely divided, with a stout basal sheath clasping the stem.
 The flowers are usually yellow, rarely white, produced in large umbels.
 Many plants of this genus, especially "F. communis" are referred to as "giant fennel," although they are not fennel in the strict sense.
Ferula is a genus of flowering plants.
Austrobaileyales is an order of flowering plants, consisting of about 100 species of woody plants growing as trees, shrubs and lianas.
 Perhaps the most familiar species is "Illicium verum", from which comes the spice star anise.
 The order belongs to the group of basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the Amborellales and Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade.
 The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, "Austrobaileya scandens", a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essential oil-bearing trees and lianas.
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.
Pterostylis atrans, commonly known as the dark-tip greenhood or blunt-tongue greenhood, is a species of orchid endemic to south-eastern Australia.
 As with similar greenhoods, the flowering plants differ from those which are not flowering.
 The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering spike.
 In this species, the flower is green and reddish brown with a protruding sinus and small club-like tips on the ends of the lateral sepals.
Watercress is an aquatic plant species with the botanical name Nasturtium officinale.
 This should not be confused with the profoundly different and unrelated group of plants with the common name of nasturtium, within the genus "Tropaeolum".
Pterostylis angusta, commonly known as the narrow shell orchid, is a species of orchid endemic to the south-west of Western Australia.
 As with similar greenhoods, the flowering plants differ from those which are not flowering.
 The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering spike.
 In this species the flower is green, white and brown with an inflated base, a narrow hood and the longest labellum of any Western Australian "Pterostylis" species.
Pterostylis striata, commonly known as the mainland striped greenhood, is a species of orchid endemic to south-eastern mainland Australia.
 As with similar orchids, the flowering plants differ from those which are not flowering.
 The non-flowering plants have a rosette of leaves but the flowering plants have a single flower with leaves on the flowering spike.
 This greenhood has a white flower with prominent dark green stripes and a brown-tipped dorsal sepal with a thread-like tip.
 Mainland striped greenhoods were formerly described as "Pterostylis alata" but that species is now recognised as a Tasmanian endemic.

Question: Are both  Ferula and Watercress a species of flowering plants?
Answer: no
