Hello Everyone,
I am quite familiar with Lloyd's work (1942) regarding Byblis gigantea. However, I've never been too impressed with fig. 9 plate 9 which supposedly shows the sessile glands. Plus, there is no mention of pulvini appendages whatsoever. Therefore, to clear up any murkiness, please review the following photos. I've added some slight spectral enhancement, since they are smaller than a needlepoint!
And finally, one with a little alternate lighting;
Now, let's take a world-wide look at Byblis 'Goliath' and Byblis 'David' and their pulvinic appendages, from the mouths of other Byblis growers.
Greg Allen's posts from the UK, which is an entire ocean away from me. This first post documents pulvini in two proposed Byblis species, "B. guehoi" and "B. rorida".

His next post documents pulvini in the proposed species B. aquatica;

While we're on the subject of "B. aquatica", let's take a look at 'in situ' photos by Phil Mann, compliments of Bob Z's fantastic CP Photofinder. Pulvinus is clearly seen in the photo;

Moving right along...Cindy (from Singapore) which his half a world away from me, shows pulvinus in all of her photos of the proposed species "Byblis liniflora" also known as Byblis 'David';

Now, let's look at German Byblis grower Denis Barthel's proposed "Byblis liniflora" photo. Again, other side of the globe from me;

Proposed species "B. aquatica" photo from the same grower. Pulvini visible;

And proposed species "B. filifolia" once again from Denis with more pulvini;

And lastly, a fairly recent post from Katie. She describes how her Byblis 'Goliath' pedicels are moving via pulvini, along with other proposed Byblis species as well;

Whew! Now hopefully that should adequately clear up any doubts about pulvinic appendages in Byblis 'Goliath' and Byblis 'David'.
While on the subject of Byblis pulvinus, my latest results from my experiments are showing that pulvinus size could also be related to wet/dry extremes. My latest theory is that the pulvinus doesn't always just provide movement, but may also double as a water storage organ as well during dry periods. Although now I have proven that the existence of pulvini in Byblis is persistant in all proposed Byblis species (since I've always firmly believed B. gigantea and B. lamellata to be the same plant), my results are showing that the pulvini can vary in size as well, due to cultivational extremes. I firmly believe that this anomaly occurs 'in situ' as well. More results to follow soon!
