Taxonomic Diagnosis from Leisman 1986, p. 232:
“Growth rings present. Vessels single or in radial multiples of up to four; vessel diameter 60-250 µm (most in 100-200 range); vessel members 80-550 µm in vertical length with simple perforation plates. Vessel walls adjoining parenchyma or fibre cells have simple, elongate, usually scalariform pits up to 36 µm in length; those adjoining other vessels have circular bordered pits 10-13 µm in diameter. Tyloses common.
Wood fibers elongate and with pointed ends, up to 1.5 mm long and 20-45 µm in diameter. Fibre wall about 5 µm in thickness; large lumen. Pits simple, slit-like.
Oil cells vertically elongate, cylindrical with rounded ends; usually single, occasionally in pairs or groups of three; usually adjacent to wood rays; 80-100 µm in diameter and 550-600 µm in vertical length. Oil droplets common in cells.
Xylem parenchyma sparse, in tangential bands up to 15 cells wide, probably paratracheal, rectangular in section view, 10-15 by 20-30 µm.
Wood rays usually multiseriate, up to 5 cells wide at middle tapering to pointed ends at top and bottom, composed exclusively of horizontally elongate parenchyma cells 30-40 µ m in diameter by 50-90 µ m long.”

Specimens
Specimens that Leisman identified, implied were or said contained Cryptocaryoxylon gippslandicum Leisman 1986 that we are aware of are:
We are currently unaware of any specimens in the L. R. Wilson Paleobotany and Micropaleontology Collection, Sam Noble Museum of Natural History, Norman, Oklahoma, United States (OMNH). However, some are in other repositories/collections.
We use the following abbreviations in describing the repository (usually either a museum or university collection) that the specimens/material are owned and stored:
NMV-P = Palaeobotany Collection, Museum Victoria, Melbourne, Victoria, Australia
Note: Abbreviations are the same as those listed in The Global Registry of Biodiversity Repositories (GRBio) unless no registered abbreviation or collection code was listed which are noted.
Before any sorting, we list the specimens numerically by Leisman number. The columns are sortable by clicking on the heading. The first click to a heading sorts them alphabetically (A to Z)/numerically (1-25). The second click to heading sorts them reverse alphabetically (Z to A)/numerically (25-1). The third click to heading brings back to original sort order.
We are aware that Leisman and his collaborators identified Cryptocaryoxylon gippslandicum Leisman 1986 in the specimens/materials listed in the table.
