Mac Is Back!

Day 258: Mac is back! Last year, my "pet" Corallorhiza maculata was nipped off by something (deer, slug, squirrel...I don't know who the culprit was) when it was only about six inches tall. This year, she's making up for lost time by putting up two stalks which, as you can see here, are just beginning to flower. I've done my best to protect the plant by installing an 18" high chicken-wire fence around it, staked to the ground with short lengths of bamboo garden wand. That said, the Corallorhizas are amazingly resilient. Many can remain in a dormant state for years without ever breaking ground. The key lies in the plants' companion fungi. Each species of Coralroot has one or more specific "companion" fungi on which they depend. The fungi break down nutrients in the soil which can then be taken up by the plant. Currently, there is debate among botanists as to whether this is parasitism (in which case the fungus derives no benefit from the plant) or true mycoheterotrophy (a cooperative arrangement in which plant and fungus provide some requirement). I hold with the latter view on the hypothesis that if a long-term partnership has evolved, then it must in some way be advantageous to both parties. Despite the fact that we haven't identified what that exchange might be, absence of evidence does not negate the possiblility of it existing in some way we cannot detect. Good science is inquiry, not denial.
