TL;DR: It is concluded that an ambitious goal to describe 10 million species in less than 50 years is attainable based on the strength of 250 years of progress, worldwide collections, existing experts, technological innovation and collaborative teamwork.

TL;DR: The structure of the ontology and the design principles the authors used in constructing PO terms for plant development stages are described and details of the methodology and rationale behind the revision and expansion of the PO to cover development stages for all plants are provided.

TL;DR: The taxonomic status of the Mexican cycad Ceratozamia brevifrons is reassessed based on information from habitat, herbaria and living collections in the Botanic Garden ‘Jardín Botánico Francisco Javier Clavijero’ and a neotype is designated for C. breVifrons and a description is presented.

TL;DR: Floristically, Zamiaceae is represented in Colombia by four elements: a Chocó, southern Córdoba, and northeastern Antioquia element, with the endemic genus, Chigua, and six species of Zamia, and an element east of the Andes and principally Amazonian, with four other species, Z.encephalartoides.

TL;DR: The Ceratozamia species from the Sierra Madre Oriental, Mexico, are circumscribed using morphological characters, including a detailed evaluation of reproductive structures such as the apex, position, color and shape of the ovulate strobilus.
