Remarks[“Aug. 9. . . P. M. Up Assabet. . . Again I am surprised to see the Apocynum cannabinum close to the rock at the Island, several plants, apparently not more than ten days out: say July 25th, including the ones I saw before. The flowers of this are white, with divisions of the corolla erect or nearly so, corolla not one eighth of an inch wide, calyx-segments lanceolate, pointed, as long as the tube of the corolla. I now notice that all the branches are about equally upright, and hence the upper ones are much more upright than the upper ones of the A. androsaemifolium. The plant is inclined to be taller and narrower than that, perhaps because it grows by water. The leaves are more oblong or lanceolate and pointed, the downiness and petioles about the sam with that of the common; in this case, non heart-shaped. . . this, a white one with still longer calyx-segments and no heart-shaped leaves. This is rather smooth.” Journal 8: 457-458. 1856]

LocalityStone bridge
Remarks[“Aug. 5. . . At the Assabet stone bridge [Elm Street/Route 2 bridge], apparently freshly in flower, - though it may have been out nearly as long as the androsaemifolium, - apparently the Apocynum cannabinum var. hypericifolium (?). The tallist is four feet high. The flowers very small (hardly more than an eighth of an inch in diameter), the segments of the corolla not revolute but nearly erect. There are twenty to thirty flowers at the end of a branch. The divisions of the calyx are longer than in the common, long ovate. Yet it differs from Gray’s hypericifolium in having the cymes not shorter than the leaves, and the tube of the corolla rather longer than the divisions of the calyx. The leaves are hardly more downy or heart-shaped below than the common. Hypericifolium is a separate species in Pursh and some others. And the branches are less ascending than the common, making an angle of about 62° with the stem (the four lower), while three of the lower of a common one make an angle of 44°” Journal 8: 445, 447-448. 1856]
