December 2013 – Guess This Plant
This is the FNJP’s 35th edition Guess that Plant
The December Guess that Plant will be played differently. As the saying goes “we don’t see the forest for the trees“, so this month we decided we will get real close; so close all you can see is the bark.
Above are two photos of New Jersey’s most common yellow pine species: Pitch Pine (Pinus rigida) and Short Leaf Pine (Pinus echinata). The task this month is to attach the correct name to the correct photo. Any ideas who is who? Let us know if you figured out this month’s featured “Guess that Plant”.

Last Month’s Plant:
November’s Guess that Plant
Cyperus strigosus L.
Straw Colored Umbrella Sedge
The November Guess That Plant is a native, wetland sedge common to open wet farm fields, marshes and road side ditches. The straw colored umbrella sedge is found in all counties but less so in the center Pine Barrens where Hough (1983) describes it as intrusive.
This umbrella sedge is one of our largest and most prevalent within the genus Cyperus. Its straw colored spikelets clustered on long peduncles are one of the first clues to its identity. The individual spikelets have long, golden, acute scales with a green mid rib (Fernald, 1950). Second, it is a perennial from a single corm-like base. Unlike Yellow Nut Grass (C. esculentus) this species does not produce rhizomes. Similar perennial species are Cyperus lacastriensis (S1) and C. retrofratus (s1), both of which are very rare species in uplands or found higher along local wetland gradients than our species of the month.
