Viburnum. CAPRIFOLIACEiE. 11 



* * Leaves pinnately and conspicuously veiny with straight veins (impressed-plicate above, promi- 

 nent beneath and the lowest pair basal), thinnish, coarsely dentate: stipules subulate-setaceous: 

 cymes pedunculate, about 7-rayed: stone of the drupe more or less sukate. Akrow-wood. 



-1— Stone and seed flat, slightly plano-convex: leaves all short-petioled or subsessile. 

 V. pubescens, Pursh. Slender, 2 to 5 feet high : leaves obloug- or more broadly ovate, 

 acute or acuminate, acutely dentate-serrate (Ig- to 3 inches long, ou petioles 2 to 4 lines long, 

 or up]jer hardly any), soft-tomentulose with simple downy hairs beneath, but varying to 

 slightly pubescent (and in one form almost glabrous with upper face lucidulous) : peduncle 

 generally shorter tlian the cyme : drupe oval, 4 lines long, blackish-purple, flattened when 

 youug ; stone lightly 2-suk'ate on the faces, margins narrowly incurved, no intrusion on 

 ventral face.— Fl. i. 202 (excl. habitat, and syn. Michx.) ; Torr. Fl. i. 320; DC. Prodr.

•i— -K- Stone deeply sulcate-intrudod ventrally : transverse section of seed about three-fourths 

 annular, with flattish back: leaves rather slender-petioled. 



v. dentatum, L. Shrub 5 to 15 feet high, with ascending branches, glabrous or nearly 

 so, no stellular pubescence : leaves from orbicular- to oblong-ovate, with rounded or sub- 

 cordate base, acutely many-dentate (2 or 3 iuches long) ; primary veins 8 to 10 pairs (some 

 of them once or twice forked ) , often a tuft of hairs in their axil : peduncle generally longer 

 than the cyme : drupe ovoid, three lines long, terete, bright blue, darker at maturity. —

 Seems to pass into following, but the extremes widely different. 



V. molle, Michx. Young shoots, petioles, cymes, &c. beset with stellular pubescence : 

 leaves orbicular or broadly oval to ovate, more crenately dentate, soft-pubescent at least 

 beneath (larger 4 inches long); veins of the preceding or fewer: petioles shorter: drupe 

 4 lines long, more pointed by the style: calyx- teeth more conspicuous. — Fl. i. 180, but 

 foliage only seen; Gray, Man. ed. 3 & ed. 5, 206. V. dentatum, var. semitomentosum, Michx.

 V. scabreUum, Chapm. Fl. i. 72. — Coast of New England (Martha's Vineyard, Bessey) to 

 Texas : flowers at the north in summer, later than V. dentatum. 



* * * Leaves lightly or loosely pinnately veined, of firmer or somewhat coriaceous texture, 

 petioled, mostly glabrous: stipules or stipule-like appendages none: mature drupes black or 

 with a blue bloom, mealy and saccharine; the stone and seed flat or lenticular, plane: winter- 

 buds of few and firm scales: petioles and rays of the cyme mostly lepidote with some minute 

 rust}' scales or scurf. 



■i— Cymes peduncled, about 5-rayod: drupes globose-ovoid, 3 lines long: stone orbicular, flattened- 

 lenticular: shrubs 5 to 8 or 12 feet high, in swamps. 



V. Cassinoides, L. (Withe-rod.) Shoots scurfy-punctate: leaves thickish and opaque 

 or dull, ovate to oblong, mostly with obtuse acumination, obscurely veiny (1 to 3 inches 

 long), with margins irregularl}^ crenulate-denticulate or sometimes entire: peduncle shorter 

 than the cyme. — Spec. ed. 2, ii. 384 (pi. Kalm), excl. syn., at least of Mill. & Pluk. ; Torr.
