var. densata = Pinus x
densata (P. tabulaeformis x P. yunnanensis) - recent DNA studies
confirm the hybrid parentage here.
var. henryi - cones more
distinctly ovoid-globose, 2.5-5.0cm long (easily 4.0-9.0 in
typical var.), first year stems more glaucous or pruinose,
needles 7-12cm x 1mm (6-15cxm x 1.2-1.5mm in typical var.)
var. mukdensis - bark
more fissured, colored gray (more reddish-brown to greyish-brown
in typical var.)
'Rowe' - a listed name
with Stanley and Sons Nursery (online catalog 2003). Probably
from the famed Arboretum of this name - one that has yielded
many fine, worthy clones in several coniferous genera.
var. umbraculifera -
habit more umbrella-shaped. It has been thought it was confused
with P. densiflora f. umbraculifera but others insist one
variant belongs to this species. It a probably just a wider
selection of any already tabletop-like species.Very old trees in
Chinese gardens certainly fit this general description. If a
distinct clone or two immerges they would deserve a cultivar
name.
