Examples of noteworthy species published in the journal include Beccariophoenix alfredii[17], Marojejya darianii[18], and a palm with underground flowers,[19][20] Pinanga subterranea[21].

The Sneeds were long-time IPS members who traveled the world in search of palms[33] and wrote about their adventures in the pages of Principes.

In 2006, a photo of an unidentified, large, monocarpic, fan palm in Madagascar was posted on PalmTalk, the society's online forum.

[34] This photo led botanists to the site and to the discovery and description of a monotypic genus new to science, Tahina, which was published in 2008.

[35] In 2020, the IPS launched its annual Save the Species campaign to raise awareness and funding for targeted palm conservation projects around the world.

"[39] The first meeting of the membership of the Palm Society was held at Fairchild Tropical Garden in Miami, Florida, on April 17 & 18, 1958.

In addition to electing officers and directors, the members were treated to an illustrated lecture "Palms through a Botanist's Eye" by President-elect Dr. Walter H. Hodge.

[41] PalmTalk is the popular interactive forum provided by the IPS on which users can post photos and discussions on palm-related topics.
