Bayberry

It twisted and turned, and, the first thing I knew, made a sudden bend around a bunch of bayberry scrub and opened out into a big clear space like a lawn.

The two North American genera are Myrica (bayberry) and Comptonia (sweet-fern).

[T]heir shape was much like a Figg, but very much smaller, some being about the bigness of a Bay-berry, others, and the biggest, of a Hazel-Nut.
