Typification of Juniperus pingii W.C.Cheng (Cupressaceae)

W.C.Cheng validly published the name Juniperus pingii W.C.Cheng in 1944 by providing a validating Latin diagnosis in de Ferré (1944), but he failed to cite any specimen. He repeated the publication of the name in 1947 with the same Latin diagnosis; he thus published an isonym “J. pingii” under Art. 6 Note 2. Cheng (1947) lectotypified the name J. pingii when he designated W.C.Cheng 1015 as the “type” of the isonym. Farjon (2005) overlooked this early designation and his lectotypification of the name with the illustration from the 1944 protologue is not effective as the W.C.Cheng 1015 specimen is extant.

Polyphasic reassessment of a yellow rice fungus, Penicillium toxicarium

From historical strain records, Penicillium citreonigrum NBRC 4692 was originally isolated as the toxigenic fungus responsible for the yellow rice incident in Japan in 1937. The fungus was named Penicillium toxicarium by I. Miyake, which was considered invalid due to the lack of a Latin diagnosis. Initially, it was named Penicillium sp. by Miyake et al. in 1940. Subsequently, P. toxicarium, which was erroneously cited as synonym of P. citreo-viride, was validated by C. Ramírez in 1982 with a Latin diagnosis and type designation (CBS 351.51). Later, CBS 351.51 was assigned to Penicillium trzebinskii by Houbraken et al. in 2014. In 2016, P. toxicarium was treated as a synonym of Penicillium citreosulfuratum based on a conclusion of molecular phylogenetic analysis. Recently, we discovered the taxonomic and nomenclatural short communication (in Japanese) by I. Miyake in 1947 on P. toxicarium sp. nov. with its Latin description and four illustrations but lacking the type designation. In this paper, we re-examined strain NBRC 4692 for its current taxonomic position based on morphological characteristics and molecular phylogenetic analysis. NBRC 4692 (received from I. Miyake in 1951) has been found to have the same morphological characteristics as P. toxicarium, as was shown in Miyake's diagnosis in 1947. Phylogenetic analysis revealed that the NBRC strain belongs to a unique clade, different from the clade comprising P. citreosulfuratum strains. As a conclusion, herein, P. toxicarium I. Miyake (1947) is reinstated as a correct name with the lectotype designation.

Taxonomic evaluation and valid publication of Sorbaria sorbifolia var. glandulifolia (Sorbarieae, Rosaceae)

Sorbaria stellipila var. glandulosa has not previously been validly published as there was no Latin diagnosis or description and no designation of a type specimen. The combination name of Sorbaria sorbifolia f. glandulosa that was proposed by T.B. Lee was also a nomen nudum. However, recent morphological, anatomical, and numerical studies have clearly identified this as a variety of Sorbaria sorbifolia. Here, we suggest this taxon as a new variety, Sorbaria sorbifolia var. glandulifolia with full description and type designation. Moreover, nomenclatural reviews, distribution maps, and an identification key to the Sorbaria taxa (one species and two varieties) in Korea are also provided.

Valid publication of the name Eriobotrya × daduheensis (Malinae, Rosaceae)

“Eriobotrya prinoides Rehd. et Wils. var. daduheensis H. Z. Zhang” was not validly published by Zhang et al. because there was no Latin diagnosis or description and no specimen was indicated as type. Recent studies showed that it was a hybrid between Eriobotrya japonica and E. prinoides. “Eriobotrya × daduheensis (H. Z. Zhang) B.Tang” was proposed, but it was a nomen nudum. Eriobotrya × daduheensis H. Z. Zhang ex W. B. Liao, Q. Fan et M. Y. Ding is validated by giving a full description and designating the type specimens in this paper.

Validation of the name Aster veitchianus (Asteraceae)

Aster veitchianus, a species endemic to western China, is widely accepted in taxonomic and phytochemical literature (e.g. Hu 1965, Li et al. 2007, Chen et al. 2011). However, its name was not validly published, because the original diagnosis given by Ling (1935: 214) was in French, not in Latin. Thus, Ling did not validate the name A. veitchianus according to Art. 39.1 of the ICN (McNeill et al. 2012). In our survey of the taxonomic literature, we have never found this name accompanied by a Latin diagnosis or description before 31 December 2011, nor by an English diagnosis or description after 1 January 2012. We herein provide an English description to accomplish valid publication of the name. The specimen X. B. Peng 6049 (Fig. 1) deposited in PE is designated as the holotype, which was the only one specimen cited by Ling (1935).

Valid publication of Turpinia pomifera var. minor (Staphyleaceae)

Turpinia Ventenat (1807: 3, non. cons.) is the largest genus of Staphyleaceae (Li et al. 2008). About 13 species are recorded from China, five of which are endemic. Turpinia pomifera var. minor C.C.Huang ex Hsu (1979: 358; see comments in Bartholomew & Zhou 2007) was firstly described in Flora Yunnanica. However, it was not validly published, because no specimen was listed in the protologue, which is contrary to Article 40.1 & 40.2 (McNeill et al. 2012). After consulting the herbarium of Kunming Institute of Botany (KUN), Chinese Academy of Sciences, we found that three gatherings (K.M.Feng 11588, 11748, 13544) were annotated as “Turpinia pomifera (Rox.) Kong [corrected as DC.] var. minor Huang var. n.” [sic] by C.C.Huang in April 1960 on the sheets. Therefore, the three gatherings will potentially have been examined by C.C. Huang and may have been used for the description of T. pomifera var. minor in the preparation of Flora Yunnanica. To validate the name of this variety, a sheet of the gathering K.M.Feng 11588 is designated as the holotype (Fig. 1). Ting-Zhi Hsu published a Latin diagnosis of this variety in 1979, which is referred to below to satisfy Article 39.1. According to Article 46.2, the authorship of the name T. pomifera var. minor remains the same

Clarifying Taxonomy and Nomenclature of Fothergilla (Hamamelidaceae) Cultivars and Hybrids

Fothergilla L. spp. are valuable nursery and garden plants. However, clear differentiation among F. gardenii Murray, F. major Lodd., and potential hybrids can be difficult based solely on morphological characteristics. The objectives of this work were to verify and describe the existence of interspecific hybrids and to clarify the proper nomenclature for cultivars of Fothergilla that are commonly grown in the nursery industry. A comparison of morphological characteristics was made among diverse clones representing both species and potential hybrids. A combination of chromosome counts and DNA contents was used to clearly differentiate among F. gardenii (2n = 4x = 48), F. major (2n = 6x = 72), and hybrids (2n = 5x = 60). It was determined that the majority of cultivars represented in commerce were hybrids. Fothergilla ×intermedia Ranney and Fantz (hybrid fothergilla) is proposed as the name for these hybrids and is validated with a Latin diagnosis. Although certain morphological characteristics can be used to differentiate between F. gardenii and F. major, the hybrids tend to be intermediate and are particularly difficult to separate from F. major on the basis of appearance. The correct classification and nomenclature for 17 different taxa are presented.

A Hybrid of Buddleja davidii var. nanhoensis `Nanho Purple' and B. lindleyana

A controlled cross between Buddleja davidii var. nanhoensis (Chitt.) Rehd. `Nanho Purple' and B. lindleyana Fort. ex Lindl. produced a hybrid. Pollen viability, male fertility, and the floral and vegetative characters are presented with a Latin diagnosis. Buddleja × luteolufaucia Elliott and Fantz is proposed as the name for this hybrid. Hybridity was confirmed using RAPD analysis.
