July, 2000, B. Ertter s.n.

Recent Literature [from BIOSIS] Jacobs, S. W. L., et al. Nassella tenuissima (Gramineae) recorded from Australia, a potential new weed related to Serrated Tussock. Telopea 8:41-46. 1998.
Initial Editorial Comments according to Source b, in California occurring as waif with "high potential" for spreading into natural areas, but conditions of cited occurrences seem not to qualify for inclusion in the flora according to criteria employed by Jepson Flora Project (27 Feb 2003)
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Treatment and author notes submitted for The Jepson Manual [Ed. 2] see Comment 1
Editorial Comments 1 Correspondence 1 indicates, in a note under Stipa, that Stipa tenuissima Trin., with Nassella tenuissima (Trin.) Barkworth as a syn, is included among a list of four taxa that are waifs in CA. [As an active waif, the taxon would have been included in the key to members of the genus, with a description only online; the fact that the taxon was not treated this way suggests that the author might have considered it to be an historical waif, or they may have had other reasons. It is also possible that the taxon in California is in fact only an agricultural, garden, or urban weed, as previously indicated in this Index. ]
