Sedge Buster Lesson 17 - Carex blanda

All righty then. Off to the east somewhere is a photo of Carex blanda. In these parts it habitates shady creek banks and terraces on deeper soils. If you click on the picture and then check out the distal ends of the peryginia, you will see that they are bent. Bent peryginia, smaller peryginia length, ca. 3.5mm and wider leaves separate C. blanda from its frequent associate Carex amphibola?

We were going to do these two together, because they are frequently encountered together in what passes for nature in these parts. But...........we are having big time problems with the new key characters that break old C. amphibola into two species in these general parts. Especially when we consider how C. amphibola is treated elsewhere. Yikes!

One of the problems we are having is finding any distichously arranged spikelets on any of our 13 specimens, even the Travis County specimens. That would mean that none of our specimens are C. bulbostylis which is geographically impossible. So what I am saying is that we are going to have to revise this here lesson following more perusal and we may have to discuss it with the WG as we repose upon her ample bosoms tonight.
