Description	[Early Thorn on hill]

Remarks

Early Thorn on hill ["June 1 P.M. - To Hill. . . The second thorn on Hill will evidently open tomorrow. It is altogether smooth while the first has downy peduncles, and its sepals are about entire while those of the first are cut-fringed. That largest and earliest thorn is now in full bloom, and I notice that its bloom is much whiter at a little distance than that of an apple tree. . . This thorn has pink anthers, seen close at hand. The leaves are very evenly distributed amid the bloom." Journal 9: 396-397. 1857]
