Here we present and discuss two palm (Arecaceae) trunk failure events where diseases, pests, and old age did not appear to be predisposing factors. A close inspection revealed anomalies in the trunks and leaves of the failed palms, suggesting that an abiotic factor related to where and how the palms were growing might be a predisposing factor. Trunks of Livistona chinensis and Washingtonia robusta failed during high-wind events but they were growing or had been grown in low-light conditions that resulted in abnormally slender trunks that likely had not attained maximum strength.

Southeast Trees, a tree planting and evaluation project in southeastern Los Angeles County and adjacent areas, is updated for recent tree plantings in Seal Beach, California. DOI: https://doi.org/10.21414/B16K58
The nomenclature, typification and distribution for 14 taxa of the genus Coccothrinax (Arecaceae) in Cuba described between 1972 and 1995 are reviewed and updated. Of the total of 36 types, 9 lectotypes and 22 isolectotypes are designated, 4 holotypes and 1 isotype are identified. DOI: https://doi.org/10.21414/B12S3B
We reviewed the nomenclature and typification of the three genera, Actinokentia, Chambeyronia, and Kentiopsis, and the eight currently accepted species comprising the subtribe Archontophoenicinae (Arecaceae) in New Caledonia. DOI: https://doi.org/10.21414/B1Z30C
Five varieties of Chambeyronia macrocarpa (Arecaceae) from New Caledonia are confirmed and/or named, typified, discussed, and illustrated. DOI: https://doi.org/10.21414/B1T88W
Southeast Trees, a tree planting and evaluation project for southeast Los Angeles County and adjacent areas, is updated for tree plantings at El Dorado East Regional Park, Long Beach, California. DOI: https://doi.org/10.21414/B1PK5M
The nomenclature, typification, and distribution of Copenicia macroglossa and Copernicia × escarzana (Arecaceae) are updated. Photographs and fragments at HAC of the holotype of C. macroglossa from Berlin that Beccari used to describe this species are identified and documented. The geographical and phytogeographic distribution of both taxa are provided. DOI: https://doi.org/10.21414/B1JS3P
The nomenclature and typification of Pseudophoenix (Arecaceae), a neotropical genus of four species, are reviewed and updated. Plumier's involvement in the description of P. vinifera is reported and discussed, and unpublished Plumier illustrations of the species present at the National Museum of Natural History in Paris are published.

The rediscovery of the Poeppig type locality of Copernicia hospita (Arecaceae) in Cuba is reported and its lectotype is designated. DOI: https://doi.org/10.21414/B19887
We supplement the description of Chamaedorea ponderosa (Arecaceae) from wild, living plants, discuss its distribution and ecology, phyogeny, and related species, and lavishly illustrate this handsome and imposing plant. DOI: https://doi.org/10.21414/B15K5Z
The moth Choreutis emplacta, another new pest of Ficus microcarpa in Southern California, is illustrated and discussed, including a pest description, host, damage and signs, biology and natural history, and management options. Potential biological predators are identified and reported. DOI: https://doi.org/10.21414/B11S31
The correct citation for the new names that Charles Wright described in Sauvalle’s Flora Cubana from 1868 to 1872 are those published in nine articles while those that appear in the reprinted book in 1873 are later isonyms. DOI: https://doi.org/10.21414/B1S88K
Southeast Trees, a tree planting and evaluation project in southeastern Los Angeles County and adjacent areas, is updated for late 2021 tree plantings at El Dorado East Regional Park, Long Beach, California. DOI: https://doi.org/10.21414/B1NK59
The nomenclature, distribution, and uses of Sabal japa (formerly S. yapa) (Arecaceae), based on Wright 3971 from western Cuba 155 years ago, are updated. New information includes a revised, accepted spelling of the specific epithet; the location and date of collection; a list of excluded names; and the designation of three lectotypes for synonyms.
