It forms circular clones of vegetative shoots from stout underground rhizomes. Flowering stems, infrequent in most occurrences, are cm long and terminate in a much-branched cluster of up to 1, spikelets, each containing up to 60 tiny flowers that develop a woolly appearance at maturity.

Black spruce hybridizes with red spruce (Picea rubens) on disturbed sites in eastern Canada and with white spruce in a few places. Reports of natural hybrids between black spruce and white spruce apparently remain unverified.

book tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine Clade: Tracheophytes. The taxonomic relationship of Picea rubens and P. mariana has long been obscure because of their similarities and the variability within many populations.

The hypothesis was tested that Red Spruce and Black Spruce are two distinct species, capable of hybridizing, and that introgressive hybridization or introgression has occurred since Pleistocene by: Development of microsatellite markers for white spruce (Picea glauca) and related species Article (PDF Available) in Theoretical and Applied Genetics (8) January with Reads.

A very low level of interspecific and introgressive hybridization was observed. Controlled crosses indicated that the infertility of P.

The. Hybridization is not always limited to two species; often multiple species are interbreeding. In birds, there are numerous examples of species that hybridize with multiple other species.

The advent of genomic data provides the opportunity to investigate the ecological and evolutionary consequences of multispecies hybridization.

The interactions between several hybridizing species can be Author: Jente Ottenburghs, Jente Ottenburghs. Bulkley river valleys, the range of white and Sitka spruce overlap and hybridization occurs between them. #Hybridization also occurs between white and Engelmann spruce and so 3-way crosses can occur depending on elevation.

#Hybridization is introgressive; that is, interbreeding between distinct species produces hybrids, which. Approximate elevat'. These plants were in a borderline alpine habitat.

They are said to be found in open areas, meadows, and spruce-fir forests. Our specimens were rather sheltered, being under an unidentified shrub and surrounded by other wildflowers. Tall .Pinaceae -- Pine family Hans Nienstaedt and John C.

Zasada White spruce (Picea glauca), also known as Canadian spruce, skunk spruce, cat spruce, Black Hills spruce, western white spruce, Alberta white spruce, and Porsild spruce, is adapted to a wide range of edaphic and climatic conditions of the Northern Coniferous Forest.Although a little less dense and strong, it is closely related to red spruce (P.

rubens), AKA Adi. It is quite possible that some "Adi" or the "eastern spruce" mentioned in Martin's prewar catalogs, is in fact white spruce or a white x red hybrid. (Black spruce, that is even closer related to red, can join in too, but is too small a tree by.
