Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Jun 2000 pers. comm. from Alan R. Smith see Comment 1
Editorial Comments 1 Correspondence 1 indicates taxonomic recognition is debatable.
Correspondence 2 17 Dec 2007 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that Isoetes howellii var. minima was published by Norma E. Pfeiffer (N. Pfeiff. in Authors of Plant Names) in Annals of the Missouri Botanical Garden 9(2): 142 (1922), based on Isoetes minima A.A. Eaton (Fern Bulletin 6: 30. 1898). [Therefore, author citation corrected to Isoetes howellii Engelm. var. minima (A. A. Eaton) N. Pfeiff., from Isoetes howellii Engelm. var. minima (A. A. Eaton) Pfeiff. previously in this Index, 14 Jan 2008.]
Correspondence 3 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by W. Carl Taylor & Jon E. Keeley see Comment 3
Editorial Comments 3 Correspondence 3 indicates that for The Jepson Manual [Ed. 2] Isoetes howellii Engelm. var. minima (A. A. Eaton) N. Pfeiff. is to remain a "minor variant" of Isoetes Isoetes howellii Engelm., with a note that recognition taxonomically remains questionable pending further research. [Based on treatment in Flora North America (2:73), for which Taylor is the first author, and in which Isoetes howellii Engelm. var. minima (A. A. Eaton) N. Pfeiff. is treated in the same non-committal way.]
