Here's what the USDA has to say about Cheese Pine Pineapple
A specimen known as Cheese Pine—collected in Guatemala in 1935—may be sweeter and richer in vitamin C than any other pineapple in the collection. And Pseudananas sagenarius, brought from the Rio Negro region of Argentina in 1938, always gets a second glance. Not a true pineapple, but a member of the same plant family nonetheless, P. sagenarius boasts a botanical quirk: The sharp, thornlike spines along its leaves arch away from the leaf tip instead of towards it. It’s an oddity that some experts are quick to notice.
