Puttyroot orchid, Aplectrum hyemale, is a winter perennial that is found throughout the eastern deciduous forest in mesic woods in much humus (Homoya 2012).
In contrast to many orchids, Aplectrum has relatively non-showy flowers that are somewhat camouflaged due to their dull coloration.
Aplectrum, which is found throughout Indiana especially in southern counties (Fig.
The objectives of this research are: 1) to establish baseline information on the population size and location of individual Aplectrum plants at Hougham Woods Biological Field Station (HWBFS) in Johnson County, Indiana; 2) to determine the stability of population size and reproductive effort of Aplectrum at HWBFS by comparing the 2012 and 2013 data; 3) to assess whether leaf size is predictive of flowering; and 4) to explore possible impacts of weather variation on Aplectrum reproduction.
Aplectrum plants in HWBFS were marked using GPS in February, 2012 and March, 2013.
Dominant late spring to early summer species are Aplectrum
hyemale, Arisaema triphyllum, Asarum canadense, Cryptotaenia canadensis, Elymus hystrix, Galium aparine, G.
