Sometimes reddish stems. The leaves have minute backwardly directed short marginal prickles. (evident on left leaf).


Easily confused with : Slender Bedstraw (Galium pumilum)[another limestone-loving bedstraw which occupies southerly limestone areas of the UK, rather than the more northerly areas of Limestone Bedstraw].

Some similarities to : Heath Bedstraw, but Heath Bedstraw loves heaths and other acidic soils rather than the alkaline of Limestone Bedstraw. Heath Bedstraw has whiter flowers.
