Cuban Plants on the Move, Mycrocycus 1000 years old?

From Botanical Gazette, August, 1907

Under the great dome the visitor finds a tropical garden the exhibit of Cuba. Growing herein is an elaborate and representative collection of trees and other plant forms which made fourteen carloads when brought from tropical Cuba. There is mycrocycus 1000 years old, royal palms, giant tree ferns, tropical lilies, bamboo, palms, bread fruit, banana trees, mangoes, guanabano, cocoanut trees, and date palms in actual bearing and the finest specimens of crotons ever shown in this country.

What is a Mycrocycus?








Wikipedia says that "Microcycas is a genus of cycads in the family Zamiaceae containing only one species, Microcycas calocoma, endemic to a small area in western Cuba in Pinar del Río Province".
This article in The Cycad Newsletter talks about their status in 2007.

Ben Macomber said in 1915

"Ancient among trees are the two specimens of microcycas from the swamps of Cuba. These Methuselahs of the forest are at least 1,000 years old, according to the botanists. They are among the slowest growing of living things, and neither of them is much taller than a man. They were seedlings when Alfred the Great ruled England, and perhaps four feet high when Columbus first broke through the western seas. In the four centuries of Cuban history they have not grown so much again. These venerable trees belong to the bluest-blooded aristocracy of the vegetable world. Ages ago they inhabited our northern states. Their family has come down practically unchanged from the steaming days of the Carboniferous period, when ferns grew growths in matted masses to form the coal measures. The fossil remains of cycads in the rocks of that period prove that they once flourished in the tropic swamps where now are the hills of Wyoming and Dakota."

Are these the Mycrocycus? I don't think so. There were only two.
Tree ferns?
