"Plate 86 Figure 3"

"Leaf oval-elliptical, wedge-shaped at base and summit, 7.2 centimeters in length by 3.8 centimeters in width across the middle; margin entire; apex apiculate; nervation simply pinnate, campto-acrodrome; midrib thin above, thick below; secondary nerves opposite or subopposite, five on each side, leaving the midrib at angles of about 40°, curving upward, thinning out and merging into one another near the margin; tertiary nervation rather widely spaced, flexed or almost straight, at right angles to the midrib and secondaries throughout."



From Hollick (1930) (p. 112)

"It is difficult to decide whether this leaf should be regarded as belonging to the Cornaceae or to the Rhamnaceae. It appears to be slightly inequilateral - a character which is common to certain species in both Cornus and Rhamnus and therefore is of no distinctive diagnostic value in deciding between them; but the subopposite character of the secondary nervation and the relatively wide spacing of the tertiary nerves would appear to indicate generic relationship with Cornus rather than with Rhamnus."
