Question
Hi, I am trying to investigate dimorphism in Pyrrosia Piloselloides for my school project but I'm not sure how. I know there are two types of fronds in this species- the fertile frond and sterile frond and I tried to study the fern cycle. How far do environmental conditions affect the dimorphism in Pyrrosia Piloselloides or is it age that affect the dimorphism? How do I quantify this data? This species can be found in North eastern India, Malaysia and almost every part of Singapore.
Answer
Dear Bambpp, I'm not sure I will be able to help you enough for your study. That written, many ferns demonstrate dimorphism between the sterile (i.e., vegetative) and fertile (i.e., reproductive) leaves. Those leaves that bear spores are sometimes very different from those leaves that do not bear spores. These differences are independent of age or habitat. You might investigate this route first. Good luck with your study.
