Matthias Asmuss pitcairnia (Pitcairnia asmussii) from Venezuela similar to Pitcairnia xanthocalyx Mart. 1848

NEWS - Matthias Asmuss pitcairnia ( Pitcairnia asmussii Gouda spec. nov.) discovered by Matthias Asmuss from Caracas, Venezuela, and cultivated at the Utrecht Botanical Gardens is similar to Pitcairnia xanthocalyx Martius (1848), but with shorter flower stalks with larger sepals and petals, and dimorphic, non-petiolate leaves. Pitcairnia L’Heritier (1788) is a mostly terrestrial genus widespread from Mexico to Argentina with a total of 217 species and about 52 species known from Venezuela. In 2015 Matthias Asmuss from Caracas collected a new Pitcairnia from Aragua, Venezuela. The specimen is kept in the VEN herbarium, but due to the chaotic period in the country, it may have been lost, only the photo remains. At Utrecht Botanic Gardens, Eric Gouda obtained a young specimen from the collection in November 2018 and it flowered in May (2024). This living specimen is next to the type specimen used for the description. Pitcairnia asmussii is an acaulescent or short caulescent plant, flow

Multi-branch wild rye (Elymus multiramosus) from China has similarities with Elymus nutans Griseb

NEWS - Multi-branch wild rye ( Elymus multiramosus Y.C. Zhang, sp. nov.) reported from Delingha City, west of Qinghai Province, China, which has similarities with Elymus nutans Griseb. However, it can be easily distinguished from other species by its compound spikes characterized by elongated rhachilla at the base of the main axis, producing 3–6 mini-thorn-like branches. Elymus L. is the most extensive genus in Triticeae, characterized by polyploid and mostly short-lived perennial grasses including about 172 species from the Arctic to subtropical regions, adapting to diverse environments such as grasslands, semi-deserts and mountains. Elymus provides important annual forage in temperate regions and especially in the Qinghai-Tibet Plateau. In October 2020, in Delingha City, west of the Qinghai-Tibet Plateau, plants with compound spikes were found in a dry and rocky alpine grassland area. Elymus multiramosus is a herb with culms are usually erect, sometimes slightly decumbent at base,
