Question: Which of the plants has more common names? Psilotum or Conophytum

full_context: Document 1: Leptosporangiate fern: Leptosporangiate ferns are the largest group of living ferns, including some 11000 species worldwide. They constitute the subclass Polypodiidae, but are often considered to be the class Pteridopsida or Polypodiopsida, although other classifications assign them a different rank. The leptosporangiate ferns are one of the four major groups of ferns, with the other three being the Eusporangiate ferns comprising the marattioid ferns (Marattiidae, Marattiaceae), the horsetails (Equisetiidae, Equisetaceae), and whisk ferns and moonworts.
Document 2: Tree fern: The tree ferns are the ferns that grow with a trunk elevating the fronds above ground level. Most tree ferns are members of the "core tree ferns", belonging to the families Dicksoniaceae, Metaxyaceae, and Cibotiaceae in the order Cyatheales. In addition to those families, many ferns in other groups may be considered tree ferns, such as several ferns in the family Osmundaceae, which can achieve short trunks under a metre tall, and particularly ferns in the genus "Cibotium", which can grow ten metres tall. Fern species with short trunks in the genera "Blechnum, Calochleana, Cnemedaria, Culcita" (Europe's only tree fern), "Cystodium, Leptopteris, Lophosoria, Sadleria, Thyrsopteris" and "Todea" could also be considered tree ferns in a liberal interpretation of the term.
Document 3: Carpobrotus: Carpobrotus, commonly known as pigface, ice plant, sour fig, and Hottentot fig, is a genus of ground-creeping plants with succulent leaves and large daisy-like flowers. The name refers to the edible fruits. It comes from the Ancient Greek "karpos " "fruit" and "brotos " "edible".
Document 4: Frond dimorphism: Frond dimorphism refers to a difference in ferns between the fertile and sterile fronds. Since ferns, unlike flowering plants, bear spores on the leaf blade itself, this may affect the form of the frond itself. In some species of ferns, there is virtually no difference between the fertile and sterile fronds, such as in the genus "Dryopteris", other than the mere presence of the sori, or fruit-dots, on the back of the fronds. Some other species, such as "Polystichum acrostichoides" (Christmas fern), or some ferns of the genus "Osmunda", feature dimorphism on a portion of the frond only. Others, such as some species of "Blechnum" and "Woodwardia", have fertile fronds that are markedly taller than the sterile. Still others, such as "Osmunda cinnamomea" (Cinnamon fern), or plants of the family Onocleaceae, have fertile fronds that are completely different from the sterile.
Document 5: Nymania: Nymania capensis is known in English as "Chinese Lantern" because of the shape of its bright, colourful fruit, and in Afrikaans as "klapper" (meaning "firecracker" because children sometimes pop the capsules for fun). It is a spare, scrubby, woody shrub or small tree, typically ) 0.5–3 m tall. It is endemic to South Africa and some closely bordering territories, especially inland regions in central, northern and eastern parts. It grows mainly in Karooid regions, among the scrub of gorges, but also in open veld and river banks in the Great and Little Karoo, Namaqualand and Kalahari. The leaves are alternate and fascicled. They are simple and more or less linear. The flowers are solitary, born on pedicels in axils. The corolla and calyx have four lobes each, with eight stamens inserted at the base of the disc, the filaments being connate at their base. The ovary is superior and sessile; it has four lobes and four locules, each containing two collateral ascending ovules. The stigma is simple and the style extends further than the stamens. The fruit is an inflated membranous capsule, 3–5 cm across, each locule forming a distinct lobe. The ripe seeds are hard and rounded, some 2–4 mm in diameter. A locule may contain less than two seeds, due to abortion.
Document 6: Ceropegia: Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753. Linnaeus thought that the flowers looked like a fountain of wax. From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998). They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
Document 7: Gnetophyta: Gnetophyta is a division of plants, grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: "Gnetum" (family Gnetaceae), "Welwitschia" (family Welwitschiaceae), and "Ephedra" (family Ephedraceae). Fossilized pollen attributed to a close relative of "Ephedra" has been dated as far back as the Early Cretaceous. Though diverse and dominant in the Tertiary, only three families, each containing a single genus, are still alive today. The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of conduits that transport water within the plant, similar to those found in flowering plants. Because of this, gnetophytes were once thought to be the closest gymnosperm relatives to flowering plants, but more recent molecular studies have largely disproven this hypothesis.
Document 8: Protosalvinia: Protosalvinia is a prehistoric plant found commonly in shale from shoreline habitats of the Upper Devonian period. The name "Protosalvinia" is a misnomer. The name literally means "early Salvinia", and was given in the erroneous belief that the fossils were an earlier form of the living aquatic fern "Salvinia". It is no longer believed that the fossils come from a fern, but deciding exactly what the fossils represent is still a matter of debate. This is surprising when one considers how much is known about the fossils.
Document 9: Titanopsis: Titanopsis is a genus of about 10 species of succulent plants of the family Aizoaceae, indigenous to the arid regions of South Africa and Namibia.
Document 10: Lithops: Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος ("lithos"), meaning "stone," and ὄψ ("ops"), meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Greek "-ops" means that even a single plant is called a Lithops.
Document 11: Psilotum: Psilotum is a genus of fern-like vascular plants, commonly known as whisk ferns. It is one of two genera in the family Psilotaceae, the other being "Tmesipteris". Plants in these two genera were once thought to be descended from the earliest surviving vascular plants, but more recent phylogenies place them as basal ferns, as a sister group to Ophioglossales. They lack true roots and leaves, the stems being the organs containing conducting tissue. There are only two species in "Psilotum" and a hybrid between the two. They differ from those in "Tmesipteris" in having stems with many branches and a synangium with three lobes rather than two.
Document 12: Progymnosperm: The progymnosperms are an extinct group of woody, spore-bearing plants that is presumed to have evolved from the trimerophytes, and eventually gave rise to the gymnosperms. They have been treated formally at the rank of division Progymnospermophyta or class Progymnospermopsida (as opposite). The stratigraphically oldest known examples belong to the Middle Devonian order the Aneurophytales, with forms such as "Protopteridium", in which the vegetative organs consisted of relatively loose clusters of axes. "Tetraxylopteris" is another example of a genus lacking leaves. In more advanced aneurophytaleans such as "Aneurophyton" these vegetative organs started to look rather more like fronds, and eventually during Late Devonian times the aneurophytaleans are presumed to have given rise to the pteridosperm order, the Lyginopteridales. In Late Devonian times, another group of progymnosperms gave rise to the first really large trees known as "Archaeopteris".
Document 13: Conophytum: Conophytum is a genus of South African and Namibian succulent plants that belong to the Aizoaceae family. The name is derived from the Latin “conus” (cone) and Greek “phytum” (plant). The plants are also known as knopies (buttons), waterblasies (water blisters), sphaeroids, conos, cone plants, dumplings, or button plants.
Document 14: Cunonia: Cunonia is a genus of shrubs and trees in the family Cunoniaceae. The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species (Cunonia capensis) in Southern Africa. Leaves are opposite, simple or pinnate with a margin entire to serrate. Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape (hence the common name "Butterspoon Tree" for "Cunonia capensis"). Flowers are bisexual, white, red (pink to purple), or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
Document 15: Huperzia: Huperzia is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses. This genus was originally included in the related genus "Lycopodium", from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name "firmoss", used for some of the north temperate species, refers to their superficial resemblance to branches of fir ("Abies"), a conifer. In Australia, the epiphytic species are commonly known as tassel ferns.
