Abstract Dioscorea cayenensis, one of the cultivated tropical species of Dioscorea, is an important staple in Africa, with 2500 cultivars developed. It is a vine mostly known from cultivation, but also reported as escaped in the Panama Canal Zone. In Cuba, it is listed as a transformer species with a high possibility of becoming invasive, although there are no further details. The infrequently reported sexual reproduction, the digging of the tubers and its strict environmental requirements limit the spread of this species.

Seventy-three years ago the U.S. connived in the secession of the Republic of Panama from Colombia in return for the privilege of building a canal across the Panamanian Isthmus "on a strip of land leased in perpetuity." Within this 533-square-mile zone the U.S. was to exercise, forever, all those rights that it "would possess and exercise if it were the sovereign of the territory..." Today the significance of that "if" is much debated.Although Ronald Reagan's campaign position—that the Panama Canal Zone is as much a part of the U.S. as is Alaska—has been deplored by the Ford Administration, it maintains strong support in the Senate.
