A New Species of the Genus Ophiopogon (Asparagaceae) from Guangxi, China

摘要

Based on a specimen from Guangxi, China, Ophiopogon ogisui (Asparagaceae) is newly described. This species is similar to O. tonkinensis, but differs from it in the urceolate flowers with a long pedicel. In 2006, Mr. Mikinori Ogisu collected a specimenof Ophiopogon Ker Gawl. similar to O. tonkinensis L. Rodr. (Chen & Tamura 2000) from a limestone area near the Vietnam border in Guangxi, China, at about 440 m altitude. The plant has narrowly oblong leaves with an indistinct stem. The inflorescence isa reduced panicle with relatively small purplish flowers. It differs from O. tonkinensis, however, in having urceolate flowers with a long pedicel. We therefore consider it to be a new species and name it Ophiopogon ogisui.
