Set from American
By J. Lunell
Rhus Hapemanii Lunell.
A shrub, with stout, striafe, brown, shining, lenticillate branches, foliage
large and ample, petiole and rachis together 3 dm. long: leaflets 11-17 about
1 inch apart, strongly petiolulate, acuminata 9-11 cm. long, 3-3.5 cm. wide,
oblong-lanceolate, strongly serrate, with about 15 somewhat uneven ser-
ratures on each margin, subcoriaceus, subfalcate, upper face a rich deep
green, lower scarcely glaucescent at all, especially on fruiting specimens;
panicle in flower broadly pyramidal, 2 dm. high, widest at base, in fruit of
the same height, but not exactly as wide; panicle branches tomentulose-
pubescent; druplets many, 3 mm. in diameter, subglobose with an inclination
to ovate.
Its ally, Rhus cismontana Greene, known from western Nebraska and
Kansas, is much smaller in all parts, has 11-13 leaflets, which are 4-6 cm.
long, subsessile and glaucescent beneath, and its fruiting panicle is about
9 cm. high.
The plant just described seems to be a native of southeastern Nebraska,
as it was collected near Minden, a locality situated somewhat east of the
central perpendicular line in the southern part of that state. As types have
been vised specimens collected in flower on July 8, 1912, and in fruit on
September 12, 1921, by Dr. H. Hapeman, and this species name has been
conceived with a view of doing honor to him as the discoverer of this re-
markable large and magnificent sumac.
The task of differentiating this species from its allies has been facilitated
in great part through the valued helpfulness of Dr. Edward L. Greene, who
accentuated the essential points in the determination and added to my grati-
tude by kindly sending the leaflets of Rhus cismontana both from Kansas
and Nebraska.
