Plants named in 1954

The mung bean or green gram (Vigna radiata) is a plant species in the legume family. It is mainly cultivated in East, Southeast, and in South Asia and used as an ingredient in both savoury and sweet dishes.

The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of unicellular algae found in freshwater and moist terrestrial environments, less common today than they were during the Proterozoic. The stated number of species in the group varies from about 14 to 26. Together with the much larger sister taxa Rhodophyta (red algae) and Viridiplantae/Chloroplastida (green algae and land plants), they form the primary algae clade Archaeplastida. The glaucophytes are of interest to biologists studying the evolution of chloroplasts as they may be similar to the ancestral

Buglossoides arvensis (syn. Lithospermum arvense), known as field gromwell, corn gromwell, bastard alkanet, and stone seed, is a flowering plant of the family Boraginaceae. It is native to Europe and Asia, as far north as Korea, Japan and Russia, and as far south as Afghanistan and northern Pakistan. It is known in other places as an introduced species, including much of North America and Australia.

Austrocedrus is a genus of conifer belonging to the cypress family (Cupressaceae). It has only one species, Austrocedrus chilensis, native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude. It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar. The generic name means "southern cedar". It is a member of subfamily Callitroideae, a group of distinct Southern

Jacobsenia is a genus of flowering plants belonging to the family Aizoaceae. It is native to the Cape Provinces in the South African Republic.

Macadamia tetraphylla is a tree species in the family Proteaceae native to Australia. Common names include macadamia nut, bauple nut, prickly macadamia, Queensland nut, rough-shelled bush nut and rough-shelled Queensland nut.

Quercus ajoensis is an uncommon North American shrub with the common name Ajo Mountain shrub oak. It has been found in Arizona mountain ranges of the Colorado desert, and Arizona uplands of the Sonoran Desert. Q. ajoensis integrates with Q. turbinella and is difficult to determine specimen identification due to hybridization. It appears that this species is an elevation variant of Q. turbinella and is best treated as a subspecies or variety as it has been treated in the past. The status of Q. ajoensis as a species is probably unnecessary due to complete integration with Q. turbinella or it

Didymoplexiella is a genus of flowering plants from the orchid family, Orchidaceae.

These are mycoheterotrophic plants lacking chlorophyll, obtaining nutrients from fungi in the soil. Didymoplexiella borneensis (Schltr.)

Carissa bispinosa grows as a shrub or small tree up to 5 metres (16 ft) tall. Its fragrant flowers feature a white corolla. The fruit is red when ripe. Its habitat is woodland and forest from 1,080 m (3,540 ft) to 1,630 m (5,350 ft) elevation. Vernacular names for the plant include forest num-num and Y-thorned carissa. Carissa bispinosa is native an area from Uganda to South Africa.

Scilla litardierei, the amethyst meadow squill or Dalmatian scilla, is a species of flowering plant in the family Asparagaceae. A bulbous perennial, with blue grape-hyacinth like flowers, blooming in late spring, much later than the more popular Siberian squill and later than Muscari which it resembles.

Schoenoplectus acutus (syn. Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris subsp. acutus), called tule , common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word tōllin [ˈtoːlːin], and it was first recognized by the early Spanish explorers and missionaries in New Spain who saw the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City being used to construct

Asclepias asperula, commonly called antelope horns milkweed or spider milkweed, is a species of milkweed native to the Southwestern United States and northern Mexico.

Antiphiona is a genus of flowering plants in the daisy family. Species Both known species are endemic to Namibia. Antiphiona fragrans (Merxm.) Merxm. Antiphiona pinnatisecta (S.Moore) Merxm.

Lilium arboricola is an epiphytic lily species with green flowers, and orange-red anthers. It was first botanically described by Francis Kingdon-Ward and his assistants Chit Ko Ko and Tha Hla after a collection in the Shan region of Myanmar in 1953. Specimens from this collection flowered once in cultivation in Great Britain and were then lost. It was thought that it had been rediscovered in Lao Cai, Vietnam, in 2006, and introduced thence to Britain and Canada, but this turned out to be a new species (Lilium eupetes)

Elymus trachycaulus is a species of wild rye known by the common name slender wheatgrass. It is native to much of North America. It grows in widely varied habitats from northern Canada to Mexico, but is absent from most of the southeastern United States. It is variable in appearance, but generally bears a very narrow, linear inflorescence of spikelets appressed against the stem. There are three subspecies, two very widespread and one which is limited to Greenland.

Bulbophyllum pandanetorum is a rare species of epiphytic plant in the family Orchidaceae. It is found in Cameroon and Gabon, where its natural habitat is subtropical or tropical moist lowland forests at elevations roughly between 200 and 950 meters. It is threatened by habitat loss. It was botanically described in 1954. In September 1925, the first sample of B. pandanetorum were collected, twice, in Gabon. They were both found in the Ngounie River region; the first specimen was located near Kembélé, and the second, along the River Dévèla. Both were attached to Pandanus trees, and so the
