Pelagodoxa henryana (Arecaceae): a supplement of additional photographs and figures to the 2019 article in the journal PALMS.  Donald R. Hodel, Jean-Francois Butaud, Craig E. Barrett, Michael H. Grayum, James Komen, David H. Lorence, Jeff Marcus, and Ariiteuira Falchetto.  PalmArbor 2019-01: 1–24.  DOI: https://doi.org/10.21414/B1T597 

An article we wrote reassessing the genus Pelagodoxa was published in the journal PALMS [63(3): 113-146. 2019]. In it we document substantial and critical differences between the two species, P. henryana and P. mesocarpa, establish the validity and resurrect the name of the second species from synonymy, discuss molecular data, phylogeny and phytogeography, ethnobotany and conservation of Pelagodoxa and what impact, if any, they might have had in its speciation and insular distribution. We also summarize the cultivation requirements for these handsome and intriguing palms. Here we provide supplemental photographs with extended captions and tables illustrating the critical morphological characters of the genus and between the two species to support our findings further. 

 

The new Fusarium wilt disease of queen palms and Mexican fan palms is difficult to confirm from leaf samples; thus, in the presence of symptomatic leaves, internal trunk decay is necessary for disease confirmation. © 2018 D. R. Hodel.

Fusarium wilt of queen palm and Mexican fan palm: a devastating, new palm disease in California.  Donald R. Hodel and Paul Santos.  PalmArbor 2019-02: 1–17.  DOI: https://doi.org/10.21414/B1PC79 

A new Fusarium wilt disease of queen palm (Syagrus romanzoffiana) and Mexican fan palms (Washingtonia robusta), both Arecaceae, is for the first time reported in California. Here we provide a summary of this new, fatal Fusarium wilt found on queen palms in San Diego County, compare it with the original Fusarium wilt of Canary Island date palm, and discuss management strategies.  

 

Acoelorraphe wrightii, La Barbarita, Pinar del Río, Cuba, occurs in seasonally wet situations at low elevations. Here it survives in a pasture and the blackened trunks show that it is subject to periodic burning.© 2016 D. R. Hodel.

A review of the nomenclature and types of the genus Acoelorraphe (Arecaceae). Celio E. Moya López. PalmArbor 2019-03: 1–29.  DOI: https://doi.org/10.21414/B1JP41 

The nomenclature and types for all names in Acoelorraphe (Arecaceae) are reviewed and updated. Of the total of 87 types, 5 holotypes and 12 isotypes are identified while 11 lectotypes, 52 isolectotypes, 1 neotype, and 6 isoneotypes are designated.
