You know, most people spend a three-day holiday weekend lazing about, or puttering, or maybe getting a few things done that the normal schedule doesn’t allow. Oh, we did quite a bit of that. Date night on Saturday night was a matinee showing of John Carter, so the Czarina finally got the chance to see what was the big deal about Edgar Rice Burroughs’s secondmost famous creation. (Because she still has pattern nightmares over seeing David Cronenberg’s adaptation of Naked Lunch twenty years ago, I didn’t bring up the singular horror of continuing the conceit from Philip Jose Farmer’s short story “Jungle Rot Kid on the Nod” and suggest the idea of A Princess Of Mars as written by William S. Burroughs instead of Edgar Rice. Mugwumps instead of Tharks, for instance. One of these days, though, I will, when she last expects it, and her scimitar elbows will wail in the night.)

Instead, time was spent with The Plants. Plural. A new shipment of Nepenthes came in, so I can compare the suitability of several new species and hybrids for Texas life, which meant Saturday morning was spent frantically repotting them in fresh sphagnum moss. Friday was spent cleaning up the last of the mess from Tuesday’s tornado April Madness, which included clipping dead Sarracenia leaves, repotting bladderworts and triggerplants, and checking on hot pepper seedlings. On the last, thanks to the kind folks at the Chile Pepper Institute and Dilly’s Chilis, this summer should yield quite a crop of both Bhut Jolokia and Trinidad Scorpion “Butch T” peppers for those with that sort of inclination. At least, that’s the hope, and if hope was all I needed, half of Texas would have been covered with Roridula gorgonias plants last September. And so it goes.

Anyway, pulling weeds and picking whitefly makes you ask all sorts of interesting questions, and now half of my best questions are ones that require my going back to school to get answers. Some are the sort that require so much expertise that I’d probably have a couple of Ph.D theses by the time I had them answered to my satisfaction. Now, I could be greedy and hang onto these, or pass them on to folks who can do something with them. Even if the only response is a quick smack to the back of my head, at least I’ll know that someone else considered them.

The first one was relatively easy. Deadheading the current crop of Stylidium debile made me wonder if any suitably dedicated botany grad student has continued sequencing triggerplant genomes to view interrelationships between the species and with other plants. Some work is available, but dating from back in the Twentieth Century, and this only nailed down close relations to the Stylidacea. I’m considering some molecular palaeontology, by comparing the various species within Stylidium of Australian origin with those in Japan and South America. I have absolutely no proof right now, especially no fossil proof, but I have a sneaking suspicion that Stylidium or its forebears had as much variety and range in Antarctica before it froze in the Pliocene as the genus has in Australia today. Comparing genes of Australian species to those in Tierra del Fuego won’t prove that the genus used Antarctica as a bridge for a time, but it may give some additional lanes of study for understanding how the flora of Gondwana evolved as the supercontinent broke apart.

And the other? Again, this requires expertise and resources that I certainly won’t be getting any time soon. Last spring, I had a bit of an accident with several propagation flats full of Sarracenia pitcher plants. In an effort to get a more dependable source for drainage material than standard horticultural perlite, I decided to experiment with Growstone, an artificial pumice made from recycled glass. Naturally, after the plants were set and starting to emerge from winter dormancy, I get a call from the retailer, letting me know that the batch I’d purchased had a problem keeping a neutral pH. In other words, it was just a little too alkaline for most hydroponic options, and was definitely too alkaline for most carnivorous plants. Of course, I learned this right about the time the drought and heat of 2011 really kicked in, so I wasn’t sure if the plants were dying because of high pH or because they hadn’t evolved to grow and reproduce in a lead smelter.

Well, cleaning up some of last year’s batch, something interesting came up with the plants planted with Growstone as a drainage medium. Namely, most of the Sarracenia that survived were stunted and twisted, and others grew incredibly slowly. Purple pitchers, Sarracenia purpurea, though, grew much faster than expected. At that point, I remembered previous reading on how S. purpurea spread all through the eastern seaboard of North America, and then took a hard left and spread into Michigan, Ontario, and Alberta. Of particular note was that they seemed to do rather well in marl bogs in northern Michigan, and marl is extremely alkaline.

And there started the queries. S. purpurea obviously had a higher tolerance to alkaline conditions than its cousins, but how much of a higher tolerance? Did plants in the Michigan marl bogs grow more slowly than ones in more acidic soils, and was the alkalinity the only factor affecting slow growth? Best of all, what gene did S. purpurea have that its cousins lacked, what did that gene do besides control alkalinity tolerance, and could that gene be transferred to other Sarracenia? Was this something that could be introduced via standard crossbreeding techniques, or is the pH tolerance gene sufficiently recessive that it isn’t expressed in other species?

Now you understand why I still buy the occasional lottery ticket. Most people would use a gigantic windfall to quit their jobs or go on perpetual vacation. Me, I’d enroll in a school with an exemplary natural history and botany program, and I wouldn’t leave until I had my answers or a professorship, whichever came first. In the meantime, I do what I can, and pass on some of these questions to friends that can do something with them. I just tell those friends “Now, remember, after you get back with your Nobel Prize money, you owe me dinner, okay?”
