Question: Which plant species is well known by indigenous people in the tropics as a medicinal plant, Anemone or Dorstenia?
Context: Anemone riparia (thimble weed) is an upright growing herbaceous plant species in the genus "Anemone" and family Ranunculaceae.  Plants grow 30 – tall, flowering early summer but often found flowering till mid August, the flowers are greenish-white, white or even sometimes red tinted, 2 - wide.  After flowering the fruits are produced in a dense rounded, to rounded columned heads 8 mm thick.  When the fruits, called achenes, are ripe they have gray-white colored, densely woolly styles, that allow them to blow away in the wind.  This species is similar to "Anemone cylindrica" and "Anemone virginiana".  Native from Eastern North America where it is found growing on rocky banks and in open woods.  The species validity in the past has been disputed.  Differing from "A. virginiana" in the size of the fruiting heads and anthers. Dorstenia is a predominately Old and New World plant genus within the family Moraceae, but there is one "Dorstenia" species that is located in Indonesia and South Asia.  There are 105 species within this genus that are fairly equally distributed between the Afrotropics and Neotropics, second only in number to the "Ficus" genera in Moraceae, but "Dorstenia" is unique when compared to other members of the Moraceae because of their extremely diverse growth habits and life forms.  The majority of the Moraceae is woody perennials, while "Dorstenia" is dominated by herbaceous, succulent, or suffrutescent perennials, and only 10% exhibit the typical woody habit of the Moraceae.  "Dorstenia" also have a striking reproductive structure composed of clusters of bisexual flowers on disc-shaped receptacles that are often adorned with variable size and shape bracts.  Like most members of the Moraceae, "Dorstenia" have drupe fruits like peaches (peaches are not a member of the Moraceae), but another special feature of "Dorstenia" drupes is that they explode to release the seed.  The seeds are usually small with a minuscule endosperm.  The "Dorstenia" genus is also well known by indigenous people in the tropics as a medicinal plant with numerous flavonoid compounds that have anti-microbial, anti-reverse transcriptase, and anti-inflammatory effects. Otholobium pubescens is a plant species in the genus "Otholobium".  It is a Peruvian medicinal plant used for the treatment of diabetes and contains bakuchiol. Anemone tuberosa (desert anemone or tuber anemone) is a herbaceous plant species in the genus "Anemone" and family Ranunculaceae.  Plants grow 10 to 30, sometimes 40 cm tall, from a woody-like tuber shaped like a caudex.  Plants with 1 to 3 basal leaves that are 1 or 2 times ternate.  The basal leaves few with long petioles and deeply 3-parted with leaflets lacking stems or rarely with a stalk.  Plants flowering early to late spring with the flowers composed of 8 to 10 sepals normally white or pink colored, 10 to 14 mm long.  The plants produce one peduncle with one solitary flower or 2-5 flowered cymes.  Fruits in heads fusiform in shape, with 7-20 cm long pedicels.  Fruits called achenes measure 2.5-3.5 mm long and 2-2.5 mm wide with a rounded outline and flat in shape, densely woolly, not winged also with straight 1.5 mm long beaks. Althaea officinalis (marsh-mallow, marsh mallow (Persian: خطمی، ختمی‎ ‎ , Arabic: ختمية الطبية، خبيز‎ ‎ ), or common marshmallow) is a perennial species indigenous to Europe, Western Asia, and North Africa, which is used as a medicinal plant and ornamental plant.  A confection made from the root since ancient Egyptian time evolved into today's marshmallow treat. Anemone is a genus of about 200 species of flowering plants in the family Ranunculaceae, native to temperate zones.  The genus is closely related to "Pulsatilla" ('Pasque flower') and "Hepatica"; some botanists even include both of these genera within "Anemone". Medicinal plant conservation strategies need to be understood and planned for based on an understanding of indigenous knowledge and practices.  Many drugs contain herbal ingredients, and it has been said that 70–80% of the world's population relies on some form of non-conventional medicine and around 25–40% of all prescription drugs contain active ingredients derived from plants in the United States alone.  Many countries rely on these medicinal plants for the health and well being of its population, but the market demand has led to an increased pressure on the natural resources that lend to the production of some of these plants.  The most serious proximate threats when extracting medicinal plants generally are habitat loss, habitat degradation, and over harvesting.  Developing markets for natural products, particularly those that are harvested from the wild, can trigger a demand that cannot be met by available or legal supplies and demands a conservation initiative so the local populations are not exploited, causing more damage to their resources.  Many times populations are taken advantage of for their resources and knowledge, which can often be for financial gain.  Conservation of medicinal plants in its biocultural perspective not only implies conservation of biodiversity but also places an equal emphasis on conservation of cultural diversity. Dorstenia mannii is a plant species in the genus "Dorstenia". Anemone parviflora (northern anemone, small-flowered anemone) is a herbaceous plant species in the genus "Anemone" and family Ranunculaceae.  Plants grow 10 to 30 cm tall, from a thin, 2 mm thick rhizome.  Stem leaves without petioles, basal leaves few with long petioles and deeply 3-parted.  Plants flowering late spring to mid summer with the flowers composed of 5 or 6 sepals normally white or soft bluish colored, 8 to 13 mm long.  The plants produce one peduncle with one solitary flower.  Fruits in heads ovoid in shape, 10 mm long or less, fruits densely woolly, not winged and with straight 1 to 2.5 mm long beaks. Anemone lancifolia is an herbaceous plant species in the genus "Anemone" and family Ranunculaceae.  Plants grow 20 to 30 cm tall, growing from a horizontally orientated rhizome, flowering mid spring to early summer.  The flowers have white sepals that are 12-20 mm long.  This species much resembles "Anemone quinquefolia" except that it is larger growing.  After flowering fruits called "achene"s are formed in a small cluster, each achene is 3.5-5 mm long, lacks wings and has a straight or partly curved beak that is 1-1.5 mm long.
