E t y m o l o g y. Ono + strobus (= cone), is proposed to reflect the collecting locality of the holotype specimen .
G e n e r i c d i a g n o s i s. Pinaceous conifers with cylindrical seed cones having small parenchymatous bracts and larger ovuliferous scales that remain attached to cone axis at seed dispersal. Ovuliferous scale and bract separating from each other near cone axis, beginning at margins. Bract and ovuliferous scale vasculature originating from axis stele separately, ovuliferous scale trace diverging as three bundles forming an inverted U-shaped configuration. Two inverted winged seeds adaxially attached near base of ovuliferous scale; interseminal ridge absent. Wing attached toward base of seed body and laterally.
