304 CAPRIFOLIACE.E. Viburnum. 



^ 1. Lentago, DC. Flowers all similar and fertile : corolla rotate. 

 * Leaves undivided. 



1. Viburnum nudum, Linn. Sivamp Viburnum. 



Leaves somewhat coriaceous, oval or oblong, obtuse, dotted underneath with brownish 

 scales (particularly on the veins), smooth above, the margin crenulate or entire : petiole 

 somewhat margined ; cymes pedunculate ; fruit ovoid. — Torr. t^ Gr. fl. N. Am. 2. p. 14. 



var. 1. Claytoni : leaves broadly oval, oblong-obovate or oblong, somewhat shining above, 

 obtuse or slightly acuminate, entire or obscurely crenulate, slightly revolute on the margin, 

 the veins rather prominent underneath ; cyme on a long peduncle. Torr. (J- Gr. I. c. V.

 Darlingt. fl. Cest. p. 203. 



var. 2. cassinoides : leaves ovate, slightly obovate or oblong, dull above, often abruptly 

 acuminate , the margins crenate-serrate or undulate , the veins not prominent underneath ; 

 cyme on a short peduncle. Torr. <^ Gr. I. c. V. cassinoides, Linn. sp. ed. 2. p. 384; Fursh, 

 fl. l.p. 202 ; DC. prodr. 4. p. 326, not of Miclix. V. nudum, Hook.fl. Bor.-Am. 1. p. 279. 

 V. pyrifolium, Pursh, I. c. ; Torr. fl. 1. p. 318 ; Bigel. I. c. ; Beck, bot. p. 156, not of DC. 

 ^•c. V. squamatum, Willd. enum. 1. p. 327. 



Stem 6-12 feet high, slender, branching. Leaves 2-4 inches long, thickly sprinkled 

 with minute bran-like scales underneath, sparingly dotted above ; mostly entire on the margin, 

 attenuate at the base, and rather obtuse, in the first variety ; more or less crenate-serrate 

 (sometimes rather acutely), acute but not attenuate at the base, and rather conspicuously 

 acuminate, in the second. Cyme 2 - 2J inches in diameter ; the peduncle often two inches 

 long in the former var., less than an inch and often nearly sessile in the latter. Fruit about 

 one-third of an inch long, ovoid, abruptly pointed, slightly compressed, dark blue, -with a 

 glaucous bloom. Nucleus or stone much compressed, slightly convex on one side and a 

 shallow groove on the other. 



Swamps : the first variety common in the northern and western parts of the State, but not 

 found south of Hudson ; the other in the neighborhood of New- York, and I think also in the 

 cedar swamps of Long Island. Fl. May - June. Fr. September. 



Many botanists consider the V. cassinoides, Linn, (pyrifolium, Fursh, <J-r.), a distinct 

 species from V. nudum, but there are intermediate forms that seem to connect them.

 slight abrupt point, finely serrate with appressed or uncinate teeth, smooth ; petiole with a 

 very narrow and even margin ; cymes sessile or nearly so ; fruit oblong-ovoid. — Lin7i. sp. 1.
