While we're on the topic of Pipevine real fast, I've stumbled upon something of a mystery. On another blog we have a photo of ants covering the elaiosome covered seeds to Aristolochia serpentaria, Virginia Snakeroot. Supposedly though ant dispersal of seeds in this plant is inconsistent. Apparently the elaiosome often dries up, (or perhaps ants of an inappropriate size are making off with the stuff without the seeds) and the true disperser of the seed is unclear. I may have to add this cousin of the Pipevine to my garden and see what the case may be. In the mean time I'll keep an eye on all of my plants should they decide to flower this year.
Next up we have the Trilliums, which are probably the best example of myrmecochory. I did a video on it last year and will probably do another later this year. I have so many Trillium flowers I can't wait to see how many pods I'll get to mess around with.
