and the “compactness” of the stem (i.e., many vascular bundles in the stem and a very distinct boundary between stem and branch) is higher in Freycinetiainsignis, a plant with a branching morphology very similar to D. surculosa, than the stress at rupture and the “compactness” in D. reflexa. This
might be mirrored in an axial Young’s modulus significantly higher in D. surculosa (similar to Freycinetiainsignis) than in D. reflexa. It can also be hypothesized that the lack of such a “compactness” in the stem of D. marginata (see Figure 1A) and in D. fragrans [11][12] can be correlated to a lower

in arborescent monocotyledons. For a better and quantitative understanding of the functional morphology of branch–stem-junctions in arborescent monocotyledons, we investigated the two species Dracaena reflexa and Freycinetiainsignis. While D. reflexa is able to develop large arborescent forms with
using solutions inspired by plant ramifications, e.g., in automotive and aerospace engineering, architecture, sports equipment and prosthetic manufacturing.

One of the most conspicuous features of
morphology and mechanics of branch–stem-junctions have yet not been analysed quantitatively. For our studies we chose two branched arborescent monocotyledons, Dracaena reflexa and Freycinetiainsignis, in order to answer the following questions:
How are the fibrous bundles in the main stem connected to those
