Dry Limestone Prairies of Austin Texas
Added 2022-06-20 01:06:07 +0000 UTCIn this episode of Crime Pays, we visit a particularly cool habitat known as the dry limestone prairie, and are introduced to a white flowered member of the sunflower family that is especially adapted to growing on these harsh, nearly soil-less plains. Silphium albiflorum is a Texas Endemic, meaning it only grows within the geopolitical boundaries of the state of Texas. We also see a number of very cool milkweed species including Asclepias viridiflora and Asclepias asperula. And in the common native "weed" species Solanum rostratum, we observe two very cool floral traits - heteranthy and enantiostyly - and give an in-depth explanation of each. We also check out a phenomenon known as "extrafloral nectaries" on the common legume Chamaecrista fasciculata.
This 40 minute, profanity-laden bit will teach you more than any single college botany class ever could. I'm not sniffing my own farts, here...we cover a lot here. And we see some really f*cking cool plants.

Hey Joey. Got your book, love it! Are the leaves of the S. albiflorum oriented in a North/South direction, like the leaves S. laciniatum? I think I learned one new concept in my Fundies of Botany class, and it's the phylotactic spiral.

2022-07-07 14:19:39 +0000 UTCI grew up in San Antonio, and have traveled around Texas quite a lot. I love learning about the plants that I've been surrounded by my whole life. Thanks for the video! If you get a chance, go to the Enchanted Rock state natural area region. It's a granite dome sticking up out of the limestone hill country - surely a refugium for some groovy species not seen anywhere else in the Hill Country. Same for Lost Maples area. Love the new drone footage!
