A taxonomic examination of Poa annua L. var. reptans Haussknecht

Abstract

In order to examine the definition and taxonomic status of Poa annua L. (1753) var. reptans H. C. Haussknecht (1891), the taxonomic literature of the world, references of weed and turf sciences, 176 sheets of herbarium specimens deposited in KYO, Graduate School of Science, Kyoto University and seven sheets of herbarium specimens collected at golf courses in Japan, are comprehensively investigated.
As a result, the protologue of Poa annua var. reptans described by Haussknecht (1891), is estimated a book taxon and his purpose of the description was to emphasize the prostrating of the variety. It is estimated that Magchev (1912) noted another example of this variety by drawing the typical two plants in Germany according to Haussknecht (1891) .
It is proper that the variety should be cited as Poa annua L. var. reptans Haussknecht sensu A. Magchev (1912) .
