The Australian Plant Name Index (APNI) is a tool for the botanical community that deals with plant names and their usage in the scientific literature, whether as a current name or synonym. APNI does not recommend any particular taxonomy or nomenclature. For a listing of currently accepted scientific names for the Australian vascular flora, please use the Australian Plant Census (APC) link above.

Comment: "Batson (1998) introduced the name 'Agrostis castellana' into the Australian literature. In support of his argument Batson presents a table of vegetative and spikelet characters to distinguish between A. capillaris, A. castellana and A. gigantea. Tutin (1980), however, while recognising both A. capillaris and A. castellana, describes a different combination of morphological characters to distinguish them. Edgar and Connor (2000) also recognise both species but have lengthy notes describing the problems with variation, the distribution of characters, and the presence of hybrids. Edgar and Connor conclude: '...the two spp. cannot be clearly separated by spikelet characters.' Much seed of 'Browntop Bent' has been imported as either lawn or a pasture grass over the years, and it continues to be introduce. It appears (Edgar and Coonnor 2000) that much of this contained (and still does) seed that grew intp material that could be identified as two species (A. capillaris and A. castellana) with apparent hybrids and intergrades. The seed has come from a wide range of sources and, while many forms appear morphologically distinctive, they are capable of breeding with other forms when conditions for flowering are suitable. Many of these forms have been given names over the years but most of these names have fallen into disuse. Because of this, the complex, including all the varietal names in A. capillaris, is treated here under the earliest name, A. capillaris."
