2008 31 124 Guy Gusman Note on "A disjunct new population of Arisaema smitinandii S.Y. Hu (Araceae) from China"
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: In a paper that appeared in a previous issue of Aroideana (Vol. 30), the author (H. Li, 2007) extends the distribution of Arisaema smitinandii - a species originally discovered in S Thailand - to SE Xizang in China, i.e. ca. 2,300 km further to the North. Unfortunately, this conclusion is deduced on the basis of an error: the three herbarium Chinese specimens (H. Sun, Z.K. Zhou & H.Y. Yu ETM 1090, KUN!) identified as A. smitinandii by the author are the same that were used as paratypes of Arisaema tsangpoense ].T. Yin & G. Gusman (J.T. Yin & G. Gusman, 2006).
