Zusammenfassung

The morphology, anatomy and vasculature of Pinus leaves was studied. The results indicate that the Pinus leaf is always supplied with only one single vascular bundle, which is surrounded by a prominent bundle sheath. In several taxa, especially of subgenus Pinus, the vascular bundle may however be subdivided by longitudinal parenchymatic bands in the middle part of the leaf. As a result, the single bundle gets the appearance of two individual bundles, which are surrounded by a common bundle sheath. The general rule that a bundle sheath does sheath only one single bundle, as in other gymno- and angiospermous seed plants, applies therefore also for Pinus. The morphological and anatomical similarities between cladodes of Sciadopitys (Sciadopityaceae) and Pinus leaves are based on a completely different bauplan. The idea of “hidden cladodes” in some Pinaceae is therefore obsolete.
