DCD544F7882B5134A45E67C4A97C8B3D.taxon	diagnosis	Diagnosis. The new genus is characterized by having quadrangular to somewhat ribbed stems and opposite, narrowly lanceolate leaves (Figs 1, 5 A 1 - A 3). Puchiumazus is sister to a clade composed of Dodartia, Lancea and Mazus. Morphologically, it is most similar to Mazus, but it differs in having quadrangular stems, lanceolate leaves (vs. terete stems and usually obovate-oblong leaves).	en	Xiang, Chun-Lei, Pan, Hong-Li, Min, Dao-Zhang, Zhang, Dai-Gui, Zhao, Fei, Liu, Bing, Li, Bo (2021): Rediscovery of Mazus lanceifolius reveals a new genus and a new species in Mazaceae.

DCD544F7882B5134A45E67C4A97C8B3D.taxon	etymology	Etymology. The generic name is derived from " Puchiu " (in honor of Prof. Pu Chiu Tsoong (1906 - 1981), who was a prominent Chinese taxonomist specializing in the taxonomy of Scrophulariaceae in the traditional sense) and " mazus ", indicating that the new genus was separated from Mazus and is morphologically similar to it.	en	Xiang, Chun-Lei, Pan, Hong-Li, Min, Dao-Zhang, Zhang, Dai-Gui, Zhao, Fei, Liu, Bing, Li, Bo (2021): Rediscovery of Mazus lanceifolius reveals a new genus and a new species in Mazaceae.
