Sample text

Cultivation of rainforest cacti often requires mist systems to keep the humidity high, which is not something you would expect a cactus to need. each packed tightly against neighboring branches. The cushions usually are less than 1 foot (30 cm) tall, even in very old plants, and are solid enough that you could walk on them without causing damage. This compact shape helps the plants retain what little heat and moisture they have, and it also keeps the wind at bay on its surface rather than permitting it to swirl around the trunk.

Perhaps—but bark is rarely dry in rainforests, and the cactus shoots have almost no water-storage succulent tissue, so they do not appear concerned with drought. And many plants growing alongside the rainforest cacti are not drought adapted: mosses, ferns, gesneriads (the African violet family), and miniature peperomias. A simpler theory might be that cacti have moved into this habitat just as they have moved into so many others. Rather than their desert adaptations being beneficial here, they are a liability and are being lost.

Because the suitable zone is so narrow, we can jump across it to get on or off the rock without ever putting any fraileas in danger. Because the adult plants are so small, seedlings are almost microscopic, often hidden under fragments of fallen leaves. The soil is still moist from the last rain, but we are at the end of the rainy season for this year and wonder how long the dry season will last. How many of these plants will survive until next year? Although abundant here, we had checked almost every laja we encountered, and none but this one had fraileas.
