Lycophyte and monilophyte hike

This term I began again with an eastern start to the hike, if anything increasing the time spent on the east end of campus. One tree in particular forms the starting point - a Premna obtusifolia that has sporophytic moss, Lemmaphyllum accedens, Phymatosorus scolopendria, Davillia pectinata, and Davallia solida.


A heavy overcast threatened rain throughout the period, and rain was falling south of campus, but the hike remained rain free.

Last spring I took a northerly route to see the Lycopodiella cernua in the soccer field. This term a pre-walk revealed a whole new area of Lycopodiella cernua up in the area of the future student union.

Dicranopteris linearis

I started with the Dicranopteris linearis and my story of scrambling around a hill in Weno amid D. linearis looking for Lycopodiella cernua. The two maintenance crew members were puzzled by my searching the ground in an unlikely spot for anything interesting. I surprised myself when I actually did find "unen katu" amid the "anecha."

The class had actually passed through a ground stand of L. cernua, including this one with strobili. The I took the class down to the sidewalk by the dining hall and showed them the Nostoc. I dallied long enough to note the resilience of this three billion year survivor. From there I pushed west opting to move directly to the fern forest. I was briefly baffled by the loss of the trail entrance, but once I gained the trail entrance behind the hydroponic unit I found that someone had weed whacked the trail to five feet wide.

Haplopteris elongata

At the usual hilltop spot I covered the usual suspects. Not mentioned below is Cyathea nigricans, which is also present in this area.
