Title: Tree
Content: in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago). Prior to this discovery, "Archaeopteris" was the earliest known tree. Both of these reproduced by spores rather than seeds and are considered to be links between ferns and the gymnosperms which evolved in the Triassic period. The gymnosperms include conifers, cycads, gnetales and ginkgos and these may have appeared as a result of a whole genome duplication event which took place about 319 million years ago. Ginkgophyta was once a widespread diverse group of which the only survivor is the maidenhair tree "Ginkgo

Title: Muehlenbeckia complexa
Content: Muehlenbeckia complexa Muehlenbeckia complexa, commonly known as maidenhair vine, creeping wire vine, lacy wire vine, angel vine, mattress vine, mattress wire weed, necklace vine, and wire vine, is an ornamental plant in the Polygonaceae family, which is native to New Zealand. It is quite vigorous and probably the best species for trimming and topiary. It is semi-deciduous, growing to 15 ft (4.5 m) or more up suitable supports, and produces swollen white berries with black seeds. This species can become quite weedy in suitable climates if not restrained. In its native environment it plays a key role sealing human and

Title: Hawaiian lobelioids
Content: blue). It is notable in part because it has suffered so much: only three of the nine species known to science are still extant, and one of these ("D. undulata") is extinct in the wild. Several species are known only from type specimens collected in the late 1800s. Several species are very poorly known, and their status as species is questionable. For example, "D. fallax" and "D. parviflora" are both from Hawaii and their flowers are identical; it is possible that they represent different growth forms of the same species (both "Delissea" and "Cyanea" are known to undergo changes in

Title: Buckinghamia
Content: (rusty coloured) hairs; flower structures of compound inflorescences long; individual flowers creamy brown, with the dense rusty hairs on the tepals’ outer surfaces; styles shorter () than "B. celsissima" (); fruits follicles long; seeds flat with a small wing. "B. ferruginiflora"’s, restricted, endemic, distribution has obtained the conservation status of "near threatened" currently officially listed by the Queensland government legislation, the Nature Conservation Act 1992. Buckinghamia Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They grow naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland,

Title: Ilex aquifolium
Content: on the Washington State Noxious Weed Control Board's monitor list, and is a Class C invasive plant in Portland. During the Cenozoic Era, the Mediterranean region, Europe, and northwest Africa had a wetter climate and were largely covered by laurel forests. Holly was a typical representative species of this biome, where many current species of the genus "Ilex" were present. With the drying of the Mediterranean Basin during the Pliocene, the laurel forests gradually retreated, replaced by more drought-tolerant sclerophyll plant communities. The modern "Ilex aquifolium" resulted from this change. Most of the last remaining laurel forests around the Mediterranean

Question: The maidenhair tree is the sole survivor of which class of plant?
Answer: Ginko
