secured before, must be a very rare and local shrub. Certainly the 
exact limits of its distribution will be a matter for interesting investiga- 
tion. The species, so far as now known from fruiting specimens, may 
be characterized as follows: 
Viburnum Demetrionis, n. sp.—A bushy shrub, about 12 feet high: 
stems 5 fo 20, erect, terete, glabrous, becoming % to 1% inches in 
diameter, at first bright green, soon ashy gray, and at length brownish or 
grayish black, and in age much roughened with lenticels ; bark, on stems 
two years old, exfoliating in brownish sheets: bud-scales ovate, acutish, 
ciliolate, sub-carinate : leaves suborbicular, or broadly ovate, cordate with 
narrow sinus and broad rounded basal lobes, short acuminate, radially and 
sub-acutely dentate, bright green quite glabrous and sulcate-nerved 
above, somewhat paler green and soft-pubescent beneath; the larger 
ones 3% to 5% inches long, 3 to 334 inches broad: petioles furrowed 
above, glabrate, 34 to 114 inches long: stipules filiform, 2 to 3 lines 
in length: umbelliform corymbs terminal on the branches, peduncu- 
late, 2 to 3% inches in diameter, glandular-puberulent ; the primary 
Fays mostly about 7, rarely as few as 4: calyx (persisting on young 
fruit) with 5 lance-oblong obtusish hispid-ciliate teeth: fruit not very 
fleshy, oblong in outline, rounded at both ends, 5 lines long, half as. 
broad, much compressed, and in dried state concavo-convex, the convex 
surface having deep intramarginal grooves: putamen of essentially the” 
same shape.—Collected July, 1894, and May 29, 1896, by C. H. Deme- 
trio, near “Big Cave,” bluffs of Cole Camp creek, Benton county, Mo. 
Mr. Demetrio reports that on his second visit to the above locality 
he found no less than 20 shrubs of this species growing within a radius 
. @ quarter of amile. He also found, a little to the north of the “ Big 
Cave,” a second species of Viburnum, which was growing so near the 
edge of the creek that some of the branches were immersed. This. 
Species proved to be V. pubescens Pursh in all essential regards, but it 
differs from any specimens, accessible to the writers, in having petioles 
4 to6 or in some cases even ro lines long, approaching in this respect 
V. Demetrionis. Xt is, however, very different from that species in the 
ae, contour, and dentation of the leaves, and its unusually long 
Petioles may well have been due to its exceptional habitat. 
Types of V. Demetrionis will be deposited in the Gray Herbarium, 
or of the Kew Gardens, Arnold Arboretum and asi 
bu. arden, as well as the private collection of Mr. Deane.—W.-
