So far as I am aware, but two Ashes of the section Trax'inader have
hitherto been recorded from Eastern China :
—
'E. CJunensls, Eoxl)., only
known to me from Roxburgh's character, and from the figure given by
Mr. Hauburv in his ' Notes on Chinese Materia Medica,' and F. Mand-
sliurica, Rupr. The former differs by its lanceolate merely acute leaf-
lets, of which the terminal one is described as much larger than the
others, and borne on a long petiolnle, its small drooping panicles,
and polygamous flowers : of
the latter, which Regel (Tent. Fl. Ussnr.
lot) is disposed to tliiiik may be a mere variety of F. excelsior, I have
an authentic fruiting specimen, gathered by Maximowicz at Possiet
Bay ; it differs widely by its much larger oblong gradually acuminate
leaflets, finely reticulate and slightly downy beneath along the whole
midrib, cuneate and sessile, and hairy at their insertion ; the flowers
also are destitute of calyx. Like its Manchurian congener, M. David's
plant, by its dioecious flowers, shows an aflinity with the American
species. The primary costiform veins are flattened, as if subjected to
pressure, and differ from the slender elevated veins of other species.
The leaflets are more conspicuously and abruptly acuminate than in
F. (Ornns) retiisa, Champ., or F. longicmpis, S. and Z., of which latter
species Mr. Sampson has found a single tree near Canton, whether
wild or not I cannot say, though I have visited the locality.
