Equisetum giganteum
near Boquete, Panama (June, 2001). This population was
growing on an open marshy expanse in the valley of the Río Caldera.
A layer of water several centimeters deep covered the soil and
the dominant vegetation was tall grasses and shrubs. The
E. giganteum stems were about 2-2.5 m high and the largest diameter
observed was ~1.7 cm. Photos by Chad Husby.
The following photos represent the actual color of the plants
fairly accurately.
The following photos have a bluish "washed-out" cast to them
and do not accurately convey the colors of the plants. Most
of the photos I took in Panama had this "washed-out" look, possibly
due to the effects of high humidity on the film I used.
