Diversity of the hybrid forms between Siberian stone pine and Siberian dwarf pine

open access: yesПроблемы ботаники южной сибири и монголии, 2021
Siberian stone pine (Pinus sibirica) and Siberian dwarf pine (P. pumila) are Russian five-needle pines withdifferent life forms, namely upright tree and prostrate tree, respectively. Hybridization of the species was considered in thepaper from the point of view of the habitus of their natural hybrids.

Ecological and morphological studies in the hybrid zone between Pinus sibirica and Pinus pumila

open access: yesAnnals of Forest Research, 2013
In the Baikal Region, there is no phenological isolation between Siberian stone pine (P. sibirica Du Tour) and Siberian dwarf stone pine (P. pumila (Pall.) Regel) since the timing of their 'flowering' coincides.
