Rosette (botany) Rosette (botany) In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions),
Władysław Szafer Institute of Botany Władysław Szafer Institute of Botany The Władysław Szafer Institute of Botany (Instytut Botaniki im. Władysława Szafera, Polish) in Kraków, Poland is a major European herbarium containing a collection of over 650,000 vascular plants, bryophytes, algae, fungi, lichens, and various plant fossils. The vascular plant specimens are primarily from Central Europe with a specialization in alpine plants. The bryophytes are Polish, Antarctic and subAntarctic, and East African. The fossil plants are largely Central European. Main publications include "Acta Palaeobotanica", and the "Polish Botanical Journal". The herbarium was established in the 1950s by professor of botany and paleobotany, Władysław Szafer, at the
