Alex, thanks for the picture of your sanguinea's spur. Since this is the only plant I have labeled sanguinea it is good to have something to compare to. The text does say that sanguinea's spur can be branched "when short".
Here is a closeup of the spur on the larger pitcher
And here is a closeup of the spur on the next developing pitcher
For comparison, here is a spur form A plant that believe is actually ramispina though the plant is still quite immature (pitchers about 3 cm)
