Unique Adaptation of Burdock (Genus Arctium)

The Burdock is characteristically known for its fruit covered in hooks. These become particularly useful when it comes to its seed distribution: when animals pass by ripe fruit, the fruit clings onto them and is transported by the animal to another location where it will be arbitrarily dropped off. The Burdock has adapted to the environment of the Mount Royal, as it grows close to the pathway where there is a lot of circulation and people passing, hence it has adapted to the busy pathway and is using it to its advantage for reproduction.

Common Adaptation Across All Observed Species

All observed species grow near the regularly used pathway, which leads to one of Montreal’s most popular sightseeing spots. My observations’ environment is therefore almost under constant disruption and change, therefore making the common adaptation that they are very tolerant to stress. Whether it is using the traffic surrounding them to their advantage (e.g. Burdock) or having roots able to support fluctuations in the soil nutrient levels and humidity (e.g. Red Osier Dogwood).

Phylogeny Placement for the Common Evening Primrose (Oenothera biennis)

Evening Primroses are part of the Onagraceae plant family which consists of roughly 925 species according to OneZoom. The flora in this family vary mostly in their pollinators but naturally also in their shape, colour and size.
