摘要：
Sechium mexicanum is described as a new species of Sechium sect. Frantzia. It differs from the remaining species of the section by several features of the inflorescences and staminate flowers, the obovoid and completely unarmed fruits, and pollen grains with 9-10 narrow, poorly defined colpi. It is endemic to Mexico and the first member of sect. Frantzia to be recorded outside of Central America. It grows at 900-2300 m in mesophilous forests and in oak and pine-oak forests in the states of Hidalgo, Puebla, Queretaro, and Veracruz.
