一百年来，湄公硬核一直作为硬核的变种，命名为 Scleropyrum wallichianum var. mekongense，国内大部分专著记录云南野生硬核为湄公硬核，无刺，以区别于原变种硬核（有刺）。2014年对云南野生硬核进行调查，结果表明植株具刺的多少在群体内呈连续性变异。根据植物形态学和植物地理学理论，云南南部澜沧江-湄公河流域（勐腊、景洪、勐海、孟连）的野生硬核等同于海南和广西的野生硬核（Scleropyrum wallichianum）。

The scientific name Scleropyrum wallichianum var. mekongense has been admitted during the past century. In many interior literatures, the wild Scleropyrum sp. in Yunnan province was named S. wallichianum var. mekongense, and was de-scribed as “without spine” and distinguished from S. wallichianum which with spines. Field investigation of wild Scleropyrum sp. was carried out in Yunnan province in 2014. The results showed the spine quantity varied continuously in population. Ac-cording to the theories of morphology and botanical geography, the wild Scleropyrum sp. in Yunnan province was same as Scleropyrum wallichianum in Guangxi and Hainan provinces.
