Lectotypification of Abies fanjingshanensis (Pinaceae).

The type collection of Abies fanjingshanensis W.L.Huang et al. contains four specimens in the Herbarium (GNUG). Abies fanjingshanensis is lectotypified here with L.Yang 83-427 (GNUG0002022) under Art. 9.12 of the Shenzhen Code. Yong Yang, Keith Rushforth.

Introduction

W.L.Huang et al. of the is endemic to Fanjing Shan of Guizhou of south-western China (Huang et al. 1984; Fu et al. 1999). The type of the specific name is not clearly indicated. Huang et al. (1984) designated L.Yang 83-427 (GNUG) as the type in the protologue. We found four specimens with the same collection number in GNUG, two of them [GNUG0002022 (Fig. 1) and GNUG0002122] are marked with “L.Yang (杨龙)” as the collector, the third one (GNUG0002123, Fig. 2) is marked with “Y.L.Tu (屠玉麟)” as the collector and the fourth one (GNUG0000428, Fig. 3) has no collector. All four specimens were identified as and they match the characters of the species. It is reasonable to consider that L.Yang and Y.L.Tu are two collectors of a team because all four specimens were collected from the same locality Fanjing Shan on the same day 2 Nov 1983 and the two collectors are also the co-authors of the paper describing the new species. They may have collected the specimens together and gave the same number of the collection 83-427, though they wrote different collector names on the collection notes. None of the four specimens is marked with “type” or equivalent words in Chinese. As a result, the type of is not clearly indicated according to the existing original materials and we consider that the four specimens are the syntypes (Art. 9.5, Turland et al. 2018). Amongst the four specimens, two specimens are preserved with vegetative shoots having one or a few detached seed scales; one specimen (GNUG0000428) is a reproductive shoot having partially disintegrated female cones; and one specimen (GNUG0002022) is well preserved with a reproductive shoot having a good female cone. Thus GNUG0002022 is the most representative specimen and is one of the two annotated L.Yang 83-427. Accordingly, we designate it as the lectotype of here under Art. 9.12 (Turland et al. 2018).

Note.

We found one specimen photo of the type collection L.Yang 83-427 (PE00000459) in the Herbarium PE identified as and labelled with “Isotypus” by L.K.Fu on 31 Jan 1989. We consider this specimen as the isolectotype.
