以31个南方松（P. mugo sensu stricto）、11个钩状松（P. uncinata）、5个笃斯松（P. uliginosa）、1个笃斯松×南方松（P. uliginosa × P. mugo）的潜在杂种和3个樟子松（P. sylvestris）为对照，对南方松复合体的表型分化进行了验证。对22个形态和解剖学特征进行了测量和统计学检验，以描述分类群和分类群分化内的种群。所有的分类群在大多数已验证的针叶特征上都与樟子松有显著差异。在P. mugo复合体中，P. uncinata和P. mugo s明显不同。S.潜在杂交起源的群体与笃斯酵母最相似。后一分类群的种群分化强烈;其中一些更接近P. uncinata，另一些则接近P. mugo s。S.在整个采样数据中，检测到三个地理种群：第一个地理种群包括P. uncinata和两个P. uliginosa，第二个地理种群包括东喀尔巴阡山和南喀尔巴阡山。S.第三个群体包含了所有其他的黑胫松种群。S.和P. uliginosa。在P. mugo s. s.，苏台德人形成了一个独立的群体。来自比利牛斯山的Pinus uncinata反映了高水平的分化。这个分类群的边缘种群（Cebollera，Gudar，Massif Central）也不同于比利牛斯山脉的那些。分类群和居群的表型分化与cpDNA标记的结果相似。
The phenotypic differentiation of Pinus mugo complex was verified using 31 populations of P. mugo sensu stricto, 11 of P. uncinata, five of P. uliginosa, one of the potential hybrids P. uliginosa x P. mugo and three of P. sylvestris, the latter as a control. The 22 morphological and anatomical needle characteristics were measured and statistically examined to describe the taxa and the population within the taxa differentiation. All the taxa of the P. mugo complex differed significantly from P. sylvestris in most of the verified needle characteristics. Within P. mugo complex, populations of P. uncinata were clearly distinguished from P. mugo s. s. The population of potential hybrid origin was the most similar to P. uliginosa. Populations of the latter taxon were strongly differentiated; some of them were closer to P. uncinata, and others to P. mugo s. s. Within the whole sampled data, three geographic groups of populations were detected: the first included P. uncinata and two of P. uliginosa, the second contained East and South Carpathian P. mugo s. s. with the presumed hybrid population, and the third contained all the other populations of P. mugo s. s. and P. uliginosa. Within P. mugo s. s., the Sudetan populations formed a separate group. Pinus uncinata from the Pyrenees reflected a high level of differentiation. The marginal populations of this taxon (Cebollera, Gudar, Massif Central) also differed from those in the Pyrenees. The phenotypic differentiation of taxa and populations appeared similar to that which was detected based on cpDNA markers.
