Viburnum. CAPKIFOLIACEJE. 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-raycd: stone of the drupe more or less sulcate. ARROW-WOOD. 



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

 "V. pubescens, PURSH. Slender, 2 to 5 feet high : leaves oblong- or more broadly ovate, 

 acute or acuminate, acutely dentate-serrate (1^ to 3 inches long, on petioles 2 to 4 lines long, 

 or upper hardly any), soft-tomeutulose with simple downy hairs beneath, but varying to 

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

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

 young ; stone lightly 2-sulcate on the faces, margins narrowly incurved, no intrusion on 

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

-i -i Stone deeply sulcate-intruded ventrally : transverse section of seed about three-fourths 

 annular, with flatfish 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 inches 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 crenatelv 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. T*. clcntutum, var. semitomcntosinn, Michx.

 V. scalrcllum, Chapm. Fl. i. 72. Coast of New England (Martha's Vineyard, Besscy) 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, mealv 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 

 rusty scales or scurf. 



J Cymes peduncled, about 5-rayed: 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 acumiuation, obscurely veiny (1 to 3 inches 

 long), with margins irregularly crenulate-clenticulate or sometimes entire: peduncle shorter 

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

 flowers earlier than the next. 



V. nudum, L. Obscurely scurfy-punctate : leaves more veiny, oblong or oval, sometimes 

 narrower, entire or obsoletely denticulate, lucid above (commonly 2 to 4 inches long) :
