Anthodendron viscosum Reichenbach in Moessler, Handb. Gewdchsk. ed. 2, I. 

 309 (1827). 1 



Shrub to 3 or nearly 5 m. tall, sometimes low, rarely stoloniferous, with irregu- 

 larly whorled branches; young branchlets, particularly toward the apex, with 

 hirsute or strigose loosely appressed, rarely spreading hairs, otherwise glabrous, 

 yellowish, or grayish brown, rarely red-brown at the end of the first season, the older 

 branches light grayish brown; winter-buds glabrous sometimes pubescent, usually 

 brown, with 8 to 12 broadly ovate rounded at apex and usually mucronate or 

 sometimes without mucro, the basal scales sometimes long-pointed, ciliolate on the 

 margin. Leaves ovate or elliptic-obovate to oblong-oblanceolate, acute or rounded 

 and gland-tipped at apex, cuneate at base, 2 to 6 cm. long and 0.7 to 2 cm. broad, 

 ciliate, glabrous on both sides except the midrib slightly villose above and more 

 or less strigose beneath, sometimes strigillose above, particularly on leaves at the 

 end of the shoots, usually dark green above, lighter green or glaucescent beneath, 

 at maturity firm but rather thin; petioles 1 to 3 mm. long, strigillose. Flowers 

 appearing after the leaves in June or July or farther south in May, in clusters of 

 4 to 9; pedicels 0.5 to 1, rarely to 1.5 cm. long, pubescent and glandular-hirsute; 

 calyx-lobes semi-orbicular to ovate, about 1 mm. long, setosely glandular-ciliate; 

 corolla white or more or less suffused with pink, rarely deep pink, cylindric, the 

 tube somewhat dilated near apex, 1.5 to 2.5 cm. long, about one and one half times 

 as long as the lobes or sometimes little longer than lobes, rarely almost twice 

 as long, finely villose and glandular-hirsute outside, slightly pubescent inside above 

 the middle, the lobes ovate-oblong, acuminate, about 1.5 cm. long, glandular- 

 hirsute along the middle outside and finely villose; stamens exserted, somewhat 

 longer than the lobes; the filaments villose except the upper third; style 4 to 5 cm. 

 long, exceeding the stamens, finely pubescent below the middle or on the lower 

 third, pale or sometimes purplish toward the stigma; ovary glandular-setose or 

 sometimes setose and glandless. Capsule oblong-ovoid, 1.3 to 2 cm. long, glandu- 

 lar-setose and finely pubescent or sometimes glandless. 



The species is distributed from southwestern Maine through the coastal plain 

 to southeastern South Carolina, extending inland to central Massachusetts, north- 

 western Connecticut and up the valley of the Hudson River to the neighborhood 

 of Albany, 2 northern New Jersey, central and southwestern Pennsylvania, eastern

2 In the state of New York R. viscosum has been reported as far west as Oneida 

 County by Payne, Cat. PL Oneida Co. 50 (in Rep. Regents Univ. N. F.) (1865), 

 but I have seen so specimens from that locality and Professor K. M. Wiegand 

 writes me that he does not know it west of the Albany region and the Catskills.
