Abstract
The second internal transcribed spacer (ITS-2) of ribosomal DNA (rDNA) was sequenced for the three phenotypes of Arisaema ringens (Araceae). These sequences were invariant, and are therefore not systematically informative. However, when considered along with the anatomical, morph ological, cytological, and palynological data summarized here, the rec ognition of intraspecific taxa in A. ringens is not supported.
