Plants named in 2024

Lecythis pisonis, the cream nut or monkey pot, is a tropical tree in the Brazil nut family Lecythidaceae. It is known in its native tropical America as sapucaia or castanha-de-sapucaia. The fruit is shaped like a cooking pot and contains edible seeds.

Lecythis zabucajo, the sapucaia or paradise nut, is a large nut-producing tree occurring in the Guianas, Suriname, Venezuela, Ecuador, Honduras and Brazil, and which distribution range is much the same as that of the greater spear-nosed bat (Phyllostomus hastatus). Although not singling out Lecythis zabucajo, Jacques Huber noted in 1909 that fruit bats played the most important role in seed dispersal in Amazonian forests. The quality of its nuts led to the species' being introduced to numerous tropical countries, notably Trinidad, where it has flourished. The nuts are a valuable food resource

Androsace filicula is a species of flowering plant in the family Primulaceae, which was previously placed in its own genus, Pomatosace, endemic to the Qinghai–Tibetan Plateau in China.

Vincetoxicum nakaianum (Japanese tachi-gashiwa) is a species of dogbane in the family Apocynaceae that is native to Japan. Originally discovered in 1937 by Takenoshin Nakai but incorrectly as Cynanchum magnificum, it was rediscovered and described in 2024 by Ko Mochizuki and Tetsuo Ohi-Toma. In 2025, it was discovered that the plant a scent that smells like dying ants – a strategy it uses for attracting flies for its pollination. It is the first plant known to specifically mimic ant odour for reproduction.

Scottmoria rimbachii is a species of flowering plant in the family Lecythidaceae. It is a tree native to Colombia and Ecuador. It grows in lowland and montane rain forests from sea level to 3,600 meters elevation.

Yucca luminosa, more commonly referred to as its synonym Yucca rigida, is a plant species in the yucca genus native to northern Mexico. It is also commonly called silver-leaf yucca, blue yucca, and rigid blue yucca. It grows in ravines of stony soil and limestone scrubland at elevations of 1,000–2,500 metres (3,300–8,200 ft) above sea level. Yucca luminosa usually grows individual or branched 3–4 metres (9.8–13.1 ft) tall trunks, with a crown of powdery blue leaves that grow to 1 metre (3.3 ft) long and narrowly lanceolate, tapering at both ends. It forms 1–2 metres (3.3–6.6 ft) tall

Relictithismia kimotsukiensis is a species of fairy lanterns. It is placed either in the family Thismiaceae, or in the family Burmanniaceae by those who do not recognize Thismiaceae. It is the only species in the genus Relictithismia. This mycoheterotrophic plant is known only from the Kimotsuki Mountains, in the Ōsumi Peninsula, Kagoshima Prefecture, Kyushu Island, in the southern Japan. The species is assessed as Critically Endangered based on IUCN Guidelines.

Cereus alex-bragae (syn. Mirabella alex-bragae) is a species of flowering plant in the genus Cereus. This species is native to the seasonally dry area of Goiás, Brazil.

Waimiria is a genus of flowering plants in the family Lecythidaceae. It includes a single species, Waimiria amazoniciformis, a tree endemic to northern Brazil, where it grows in terre firme Amazon rainforest around Manaus. The species was first described as Eschweilera amazoniciformis by Scott Alan Mori in 1990. A phylogenetic study by Vargas et al. published in 2024 concluded that Eschweilera was polyphyletic, and that E. amazoniciformis was an isolated sister lineage most closely related to the genera Corythophora and Imbiriba. The authors placed it in the new monotypic genus Waimiria as

Solenangis impraedicta is an orchid that was described in early 2024. It was found in central Madagascar where it is pollinated by hawkmoths. Scientists noted how this orchid has an extremely long nectar spur, measuring in at about 33 cm (13 in) long.

Scottmoria is a genus of flowering plants in the family Lecythidaceae. It includes 26 species native tropical Central and South America, ranging from Honduras to Colombia, Venezuela, northern Brazil, Ecuador, Peru, and Bolivia. The genus was described in 2024 by Xavier Cornejo, who named it in honor of American botanist Scott Alan Mori (1941–2020), an authority in the neotropical Lecythidaceae. The species in Scottmoria constitute the former Integrifolia clade of genus Eschweilera. Vargas et al. published a phylogenetic study in 2024 which concluded that Eschweilera was polyphyletic, and the

Samaipaticereus herrerae is a species of cactus native to Peru formerly considered a geographical variant of Samaipaticereus corroanus.

Pinus stormiae is a species of pine that mostly grows in the northeast of Mexico in the Sierra Madre Oriental pine–oak forests, but a small disjunct population also grows in a small area of far western Texas. It was only ranked as a species in 2024 and is still considered to be a variety of the Arizona pine Pinus arizonica in some sources.

Matucana ostolazae is a species of Matucana found in Peru.

Imbiriba is a genus of flowering plants in the family Lecythidaceae. It includes seven species native to northern, central, and eastern Brazil. The species in Imbiriba constitute the former Tetrapetala section of genus Eschweilera. Vargas et al. published a phylogenetic study in 2024 which concluded that Eschweilera was polyphyletic, and the authors proposed new or revived genera, including Imbiriba, for species in the paraphyletic sections of Eschweilera.

Guaiania is a genus of flowering plants in the family Lecythidaceae. It includes five species native to northern and northeastern Brazil, the Guianas, and Venezuela. The species in Guaiania constitute the former Corrugata clade of genus Lecythis. Vargas et al. published a phylogenetic study in 2024 which concluded that Lecythis was polyphyletic, and the authors proposed new or revived genera, including Guaiania, for the paraphyletic sections of Lecythis.

Grimolobium is a genus of flowering plants in the family Fabaceae. It includes eight species native to South America. Species in the genus were formerly placed in genus Otholobium, which included both South American and African species. A phylogenetic analysis published in 2024 found that the South American species formed a distinct clade, and the new genus Grimolobium was described to include them. The genus is named in honor of James Grimes, a botanist who did distinguished work on New World species in tribe Psoraleeae.

Evelynastra is a genus of flowering plants in the family Asteraceae. It includes a single species, Evelynastra pallida, a subshrub or shrub native to northeastern and eastern tropical Africa, ranging from Ethiopia through Djibouti, Somalia, and Kenya to northern Tanzania. It grows in deserts and dry shrublands. The species was first described as Sericocoma pallida by Spencer Le Marchant Moore in 1877. In 2024 Vanessa Di Vincenzo et al. placed the species in the new monotypic genus Evelynastra. The genus is named for Di Vicenzo's daughter Evelyn, with the ending -astra referring to the
