Question: Do Haplopappus and Malvaviscus fall into the same family of flowering plants?
Context: Stanfieldia is a genus of flowering plants in the daisy family.  The single species, "Stanfieldia nealleyi", was based on "Haplopappus nealleyi" J.M. Coulter.  Existing compilations consider the application of these names to be unresolved, but annotations on the type specimen of "Haplopappus nealleyi" in the US National Herbarium suggest that they may be synonyms of "Clappia suaedifolia". 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 basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants.  In particular, the most basal angiosperms were called the ANITA grade which is made up of "Amborella" (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody aromatic plants including star anise).  ANITA stands for "Amborella", Nymphaeales and Illiciales, Trimeniaceae-"Austrobaileya".  Some authors have shortened this to ANA-grade for the three orders, Amborellales, Nymphaeales, and Austrobaileyales, as the order Illiciales was reduced to the family Illiciaceae and placed, along with the family Trimeniaceae, within the Austrobaileyales. Pterostylis chocolatina, commonly known as the chocolate-lip leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to New South Wales.  As with similar greenhoods, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves on a short stalk but the flowering plants lack a rosette and have up to thirteen green flowers on a flowering stem with stem leaves.  The labellum is dark brown with a blackish lump near its base. Haplopappus is a genus of flowering plants in the aster family. Pterostylis lineata, commonly known as the Blue Mountains leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to New South Wales.  As with similar greenhoods, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves on a short stalk but the flowering plants lack a rosette and have up to seven dark green flowers with translucent "windows" on a flowering stem with stem leaves.  The labellum is light brown with a black strip along its mid-line. Pterostylis barringtonensis, commonly known as the Barrington leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to New South Wales.  As with similar greenhoods, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves on a short stalk but the flowering plants lack a rosette and have up to seven dark green flowers on a flowering stem with stem leaves.  It is only known from Barrington Tops National Park. Pterostylis crassa, commonly known as the coarse leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to Victoria.  As with similar greenhoods, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves on a short stalk but the flowering plants have up to four relatively large, shiny dark green translucent flowers on a flowering stem with stem leaves. Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales.  It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms.  They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies.  The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016.  Some species are used in traditional medicine.  The type genus is "Chloranthus". Malvaviscus is a genus of flowering plants in the mallow family, Malvaceae.  Common names for species in this genus include Turk's cap mallow, wax mallow, sleeping hibiscus, and mazapan.  It belongs to a group of genera that differ from the closely related "Hibiscus" in possessing a fruit divided into 5 separate parts (a schizocarp), and having a style surmounted by 10, rather than 5, capitate or capitellate stigmas.  Among those genera "Malvaviscus" is distinguished by having auriculate petals and red, fleshy fruits.
