Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 25 Jun 2002 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that "DMtns" in geographical range statement and "1000"as the lower elevational range limit for Machaeranthera canescens (Pursh) A. Gray var. leucanthemifolia (Greene) Welsh in The Jepson Manual [Ed. 1] should be changed to "DMoj" and "750" respectively, based on previously misidentified herbarium sheet (JEPS85003; L. Heckard 4701, SW end of Rogers Lake, Edwards AFB, Kern Co.), and with the approval of one of two The Jepson Manual [Ed. 1] authors.
Correspondence 2 13 Jul 2004 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that David Morgan (The Jepson Manual [Ed. 2] Author for Machaeranthera) intends to recognize four genera for taxa that were included in Machaeranthera in The Jepson Manual [Ed. 1], [so that he will treat Machaeranthera canescens var. leucanthemifolia as Dieteria canescens (Pursh) Nutt. var. leucanthemifolia (Green) D. R. Morgan & R. L. Hartm.]
Correspondence 3 23 Nov 2005 e-mail from Jeff Greenhouse see Comment 3
Editorial Comments 3 Correspondence 3 indicates that Machaeranthera canescens var. leucanthemifolia was published by Stanley L. Welsh (S. L. Welsh in Authors of Plant Names) in Great Basin Naturalist 43(2): 316. 1983. [Therefore, author citation corrected to Machaeranthera canescens (Pursh) A. Gray var. leucanthemifolia (Greene) S. L. Welsh, from Machaeranthera canescens (Pursh) A. Gray var. leucanthemifolia (Greene) Welsh previously in this Index, 6 Dec 2005.]
