Correspondence 1 | 11 Dec 2007 e-mail from Jeff Greenhouse to J. Robert Haller & Nancy J. Vivrette, co-authors of Pinaceae for The Jepson Manual [Ed. 2] see Comment 1 | |||||
Editorial Comments 1 | Correspondence 1 indicates, verbatim: Hi Nancy & Bob, // I would like to try to summarize the salient points and conclusions in Friday morning's discussion with Nancy. // 1) Ponderosa and Washoe pines are to be treated as separate species. // 2) The earliest publication of the name Pinus ponderosa was by Lawson & C. Lawson (Agriculturist's Manual 354--355. 1836). Those authors ascribed the name to Douglas and provided their own description of young individuals growing in pots as well as an older specimen growing out in the Caledonian Horticultural Gardens in Scotland. There was no reference to collected herbarium specimens, thus no type was specified. This name should be cited as Pinus ponderosa Douglas ex Lawson & C. Lawson. // 3) The Lawsons description was based on living material which must have been grown from seed provided by Douglas who had acquired it from John Wood. It has been determined that Wood undoubtedly collected the seed from trees growing at higher elevation and generally north and east of the normal range of Ponderosa Pine (within the range of Washoe Pine). // 4) In an attempt to designate a type for the name Pinus ponderosa, F. Lauria (Linzer Biologische Beitraege 28:999--1052. 1996), searched for a herbarium specimen that was most clearly derived from the early garden individuals grown from the seed supplied by Douglas and therefore best represented the living material described by the Lawsons. He designated as neotype an ovuliferous cone collected in 1849 from a tree most likely to have been grown from Douglas' seed. (I have now come around to accepting that Lauria's designation is correctly called a neotype. A lectotype must refer to "original material" which is defined as any herbarium specimens or illustrations upon which the author based his or her description. Since the Lawsons only referred to living material, a neotype must be designated.) // 5) The Jepson Manual [Ed. 2] authors Haller & Vivrette have studied the cone designated by Lauria and determined that it is, in fact, a Washoe Pine cone. The ICBN rules require that, if Washoe Pine is to be considered a distinct species from Ponderosa Pine, then the name must be Pinus ponderosa Douglas ex Lawson & C. Lawson. // 6) This, for those who separate Washoe and Ponderosa pines, is counter to over a century and a half of traditional usage of the name Pinus ponderosa. It is certainly desirable to restore the traditional application of the name. This can be accomplished by invoking ICBN Art. 14 to reject the Lawsons' publication along with the neotype designated by Lauria, and conserve the name Pinus ponderosa as validly published by later author(s), with a new type. // 7) One possibility for conservation is Pinus ponderosa Douglas ex Loudon (Arboretum et fruticetum britannicum 4:2243--2246. 1838) although Loudon's description combined characteristics from Douglas' herbarium specimen of Ponderosa Pine and from the living garden specimens which represented Washoe Pine. I think it would be better to conserve and typify some other publication of the name. // 8) I think we (The Jepson Manual [Ed. 2]) should anticipate the eventual conservation of P. washoensis for true Washoe Pine and retain the use of that name for The Jepson Manual [Ed. 2]. One of our authors (Vivrette) indicated an intention to submit a conservation proposal and will choose an appropriate publication of the name, although P. ponderosa Douglas ex Loudon 1838 may not be the eventual choice. // 9) Stay tuned! // Jeff. [Therefore, author citation expanded and corrected to Pinus ponderosa Douglas ex Lawson & C. Lawson, from Pinus ponderosa Laws. previously in this Index, 25 Mar 2008.] | |||||
Correspondence 2 | Treatment and author notes submitted for The Jepson Manual [Ed. 2] by J. Robert Haller & Nancy J. Vivrette see Comment 2 | |||||
Editorial Comments 2 | Correspondence 2 indicates that for The Jepson Manual [Ed. 2] the following notes will appear: (In The Jepson Manual [Ed. 2]) Special botanical legislation possibly needed to preserve use of the name _Pinus ponderosa_; (online only) It has been determined that the neotype of _Pinus ponderosa_ actually is a Washoe Pine cone, meaning that Pacific Ponderosa Pine would need a different name. However, the name _Pinus ponderosa_ is retained here to conserve longstanding botanical usage in expectation that there will be an official proposal to conserve the name with a different type. | |||||
Correspondence 3 | 23 Nov 2010 e-mail from Bob Haller and Nancy Vivrette see Comment 3 | |||||
Editorial Comments 3 | Correspondence 3 indicates that a paper with nomenclatural changes in Pinus ponderosa has been accepted for publication, in Aliso, and that rejection of a cone of Pinus washoensis as the neotype for Pinus ponderosa and the return of the branch collected by Douglas as the type for Pinus ponderosa means that the correct author citation now is Pinus ponderosa Douglas ex Lawson & C. Lawson, and that the note indicated for The Jepson Manual [Ed. 2] under Correspondence 2 therefore had to be modified accordingly, to: Because the neotype of _Pinus ponderosa_ actually is a Washoe Pine cone, a different name for Pacific Ponderosa Pine would have been needed, so the name _Pinus ponderosa_ has been conserved with a different type by special botanical legislation. | |||||
