Sinus (at least what I understand it to be, other than the parts of your head that plants help cause hayfever to!) is the portion of the leaf where the petiole joins it. at times you'll see it 'twirl', a good example is b. 'Escargot'

Lots of other rex and rhizo's do this. I have the b. erythrophylla that 'twirls' (see attached). You'll see that it is similar to yours but is beginning to twirl and ruffle at the sinus. ( i searched the DG Garden Terms and couldnt find it, but I'll consult my garden books when I get home to make sure it is 'really' called a sinus)

You are so lucky to live in the same state as Baker's, do you ever get a chance to go there?
