Spontaneous Hybridization between Pinus mugo and Pinus sylvestris at the Lithuanian Seaside: A Morphological Survey
Figure 1
(a) Map of Kursiu Nerija spit in the seaside Lithuania with the sampling locations. (b) Arial photo of a sampling location “Avino Ragas” near Juodkrantė. P. mugo stand (1) is surrounded by naturally (2) and artificially (3) established P. sylvestris stands. The putative hybrids were sampled at the edge of the P. mugo stand. The introduced P. sylvestris may differ in flowering time from the local stand and so create more variation in flowering time and success of mating with P. mugo.
