Nomenclatural Changes in North American Lilium (Liliaceae) Mark W. SkinnerUSDA-NRCS, National Plant Data Center, P.O. Box 74490, Baton Rouge, Louisiana 70874, U.S.A. [email protected]:I. The approaching release of the Floraof North America Volume 26 requires the formalpublication of several nomenclatural changes thlatwill appear there. The proposed changes standard-ize infraspecific nomenclature in North AmericanLilium at the subspecies level, which is alppropriatefor these geographically segregated yet moripho-ietrically overlapping and intergrading taxonomicunits. Tihe changes include a new rank for Liliuim,washingtonianrn Kellogg subsp. purlpuracens�(Steam) M. W. Skinner, and several new combina-tions: L. pardalinum Kellogg subsp. pitkinense (Be-ane & Vollner) M. W. Skinner, L. pardalinium Kel-logg subsp. shastense (Eastwood) M. W. Skinner, L.pardalinum Kellogg subsp. ,ollmeri (Eastwood) M.W. Skinner, and L. pardalinum Kellogg subspl. ;ig-ginsii (Beane & Vollmer) M. W. Skinner. I.ectotlpesare designated for L. pardalinum and L. u'ashinrg-tonianum and for the synonym L. parrumn Kelloggvar. lultem Purdl. and a neotype is selected for L.washingtonianum sublsp. purpurascens. Key words: Liliaceae, Lilium. North America. Ongoing biosystematic investigations of NoirthAmerican Lilium (Skinner. 1988, 1993) compel thepublication of several new combinations that illappear in the Flora of North America. The taxarecognized and named below display significantand geographically coherent variation that is bestexpressed at the subspecies level (Thorne. 1978):morphological dimensions overlap between geo-graphically adjacent taxa, variation is roughly clin-al across zones of intergradation. and reproductiveisolation between subspecies is primarily achievedlgeographically. The new names achieve unifiornityat the subspecific rank for infraspecific lnonelrctla-ture in North American Lilium. Types are suppliedtfor one synonym. and for accepted names that cour-rentlv lack them. Because prior workers often ig-nored or were unfamiliar with each otlhier's workand/or Ihe formalities of type designation. anti fre-quently misapplied names with or without attribu-tion to prior circumscriptions, the noimeiclaturalliterature and history in western North AmericanLilium is abstruse. This prompts the often lengthydiscussions below.Liliuni pardalinum Kellogg. Hesperian 3: 300. 1859. TYPE: Illustration.

Kellogg (1859a) did not formally designatety pe material for Lilium pardalinum. At tie (Cali-fornia Academy of Sciences where Kellogg worked.rlost of tlhe types were saved from the fire followingtih earthquake of 1906 by Alice Eastwood, butnone of Kellogg's lily types (Vollmner 1939) or otheroriginal specimens survived. In his monograph. El-\"es (1877-1880) mentioned receiving a letter fromiSereno Watson in 1878 in which Watson cited someKellogg material of L. pardalinum and L. pardal-inum var. angustifolium Kellogg at his disposal. Inthe letter Watson noted that Kellogg's specimen ofL. i)rd<alinum was from Alameda County, Califor-nia (just across the San Francisco Bay from CAS):thus Alameda County can be inferred as the prob-able L Ipardalinum type locality. Watson wouldhave been at Harvard's Gray Herbarium when hewrote that letter (Stafleu & Cowan. 1988). but hisspecimrens of L. pardalinum and its variety angus-tioiilum are not at GH or other likely herbaria in-cludlig CAS. K. MO. UC/JEPS. or L S. It is likelylthe were returned by Watson to Kellogg and de-strioed in the 1906 event. The Hlesperian illustrations of the plants that Kel-logg described were prepared at his direction (Cur-ran. 1885), and an illustration of Liliumr pardalinumaccompanies the protologue (Kellogg. 1859a: fron-tispiece). Although it comles after the title page andtable of contents, this illustration has been cited astlie frontispiece (Woodcock & Stearn, 1950) and isso cited here. It is one of two such plates for Hies-NovoN 12: 253-261. 2002.
