Taxonomic revision of Pinus in Vietnam 2., New Results

Original language description

During the author’s most recent field study of Pinus in North Vietnam and within the subsequent research, several new findings have been revealed. The occurrence of P. wangii subsp. wangii was confirmed in the western part of the Cao Bang Province. The 2014 discovery of a small population of the two-leaved hard pine on karstic hills in the Bao Lac District (Cao Bang Province) was revised and the respective pine being classified as a new subspecies, P. henryi subsp. averyanovii. Two populations from Guangxi known previously as Pinus taiwanensis var. damingshanensis were also identified as this subspecies. The soft pine recently discovered in the sandstone mountains Pha Luong in the Son La Province near the border of Laos, described in 2014 as P. cernua, was studied thoroughly in the field and additionally compared with authentic samples (including the neotype material) and available data from the Chinese P. fenzeliana, revealing the presumed identity of these taxa within the known morphological variation of the latter. For this reason, P. cernua is relegated to a synonym of P. fenzeliana. Circumstances and shortcomings associated with the redundant description and a subsequent assessment of P. cernua are discussed in detail. A unique natural site of the hard pine P. latteri overlapping marginally with the area of P. fenzeliana was newly discovered on the northern slope in the Pha Luong Mountains. An important voucher specimen of the soft pine from the east of the Saravan Province in South Laos from 2013 was identified as P. dalatensis subsp. procera, which corresponds well with the oldest, but still not exactly localized, discovery of a soft pine in Indochina from 1918. The recent speculative and doubly identically created combination P. dalatensis var. anemophila was based on certain convergent characteristics and the similar general appearance of P. anemophila and P. dalatensis rather than on an assessment of diagnostic traits.
