Revision and collation of Chinese type specimens from the Harvard University Herbaria and the William and Lynda Steere Herbarium of New York Botanical Garden led to the discovery of errors in the designation of type specimens in the protologues of several taxa names. Following the Article 9.2 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code, 2018), the typographical errors of collecting number in the protologues of 64 taxa from China were corrected.

The South American genus Parodia includes taxa that are not sufficiently known from the taxonomical point of view. Based on field surveys, and review of nomenclatural types, specimens, and literature, we found an interesting species of Parodia from rocky areas in the southwest region of Rio Grande do Sul, which is here described as Parodia hofackeriana sp. nov. Geographic distribution, phenology, habitat, conservation, and morphological affinities with related species are provided.

Restrepia santanderensis (Orchidaceae: Pleurothallidinae), a new species from the western slope of the eastern Andes in Colombia

A new species of the orchid genus Restrepia from the department of Santander, in the western slope of the eastern Andes of Colombia, is described and illustrated. Restrepia santanderensis is compared with the morphologically similar R. flosculata and R. mendozae, which share having short inflorescences and small to medium yellow flowers. The new species can be recognized by its ramicauls prominently covered by brown-dotted sheaths, with the uppermost sheath elongate as long as the peduncle, the sepals partially spreading, the synsepal with glandular trichomes along the veins of the adaxial surface, the straight petals and the rectangular lip with truncate apex. Comparisons with similar species and comments on its ecology are provided.
