A TINCTURE OF THE FRESH ROOT OF APOCYNUM CANNABINUM, LINN. 
Description.—This species attains a height of from 2 to 4 feet. Stem erect, 
glabrous, or downy pubescent; éranches upright or ascending, leafy to the top. 
Leaves varying from nearly oval to oblong and sometimes even lanceolate ; dase 
rounded, obscurely cordate, or acute; petioles usually present, short, but some- 
times wanting. /nflorescence terminal, erect, many and densely flowered, cymes, 
shorter than the leaves; flowers smaller than those of the preceding species. 
Calyx: lobes lanceolate. Corolla greenish-white ; ‘ve not longer than the calyx 
lobes ; Zobes nearly erect, not reflexed. Follicles from 3 to § inches long. 
In this description only the more distinctive and differential points are given ; 
the generic description is embodied in that of the preceding species. As these 
two plants are so often classed as one by collectors in general, and as their action 
is quite different, | append a differentiation : 
A. androsemifolium. 
1, Stem divergently branching or bifurcating. 
2. Root: bark dark brown; wood white, tenacious, 
fibrous; pith of about the diameter of the thickness of 
the bark, sometimes greater.? 
3. Leaves ovate, distinctly petioled; those at the bases 
of the branches like those upon them—. ¢., an opposite, 
petioled pair.]} (Plate 132, Fig. 1.) 
Inflorescence \oose, spreading cymes; flowers greenish- 
white, with rose-colored maculations or striz, or full pale 
rose-color;§f corol/a: tube longer than the calyx lobes; _ 
fobes reflexed or spreading. 
A. cannabinum. 
1. Stem assurgently branching, not bifurcating. 
2, Root: bark grayish-brown; wood yellowish, soft, 
porous; fz¢h minute or not evident.% 
3. Leaves ranging from ovate to nearly lanceolate, 
sometimes sessile or nearly so; those at the bases of the 
branches single, sessile, and larger.|| (Plate 133, Fig. 2:) 
Inflorescence close, erect cymes; flowers greenish- 
white, smaller; coro/la: tube not longer than the calyx 
lobes; /odes erect. 
* This plant is often termed Indian hemp, a name only applicable to Cannadis Indica, as it designates that plant 
alone. American Indian hemp might possibly apply, if we consider the first two words a compound word, and write it 
American-Indian hemp. 
¢ Dog’s-bane as properly belongs to 4. androsemifolium, as Canadian hemp does to this species. ie 
¢ American hemp and American Indian hemp (so written) refer to Cannabis Indica as cultivated in America. —
