I can't access the larger images (time out error), but you may be seeing the stipules there on either side of the petiole (leafy stem / leafstalk). Stipules can look like pistils sometimes to newer growers. They are just small, slender growths on either side of a node (usually one pair on each side, stem between them). If they are more green than white, probably stipules. If they are very very slender and white (almost fragile looking) they could be preflowers...
