THE AMERICAN BOTANIST. 
Tipularia being veined, with rich purple coloring beneath, 
while the Aplectrum^ s is simply green on both sides. 
The Corallorhiza odontorhiza was another species 
which appeared in every dry woods towards autumn. Its 
near relative, the Hexalectris, was only found twice but it 
seemed to us the most beautiful of all of our orchids, while 
the circumstances of our first finding it will always be re- 
called with the astonished shouts of joy by which it was 
greeted. 
The Spirantbes cernua and S. gracilis were both found. 
It was in November that we came across a meadow quite 
white with the blossoms of the ladies' tresses" and a 
large handful was soon gathered. They possessed a deli- 
cate fragrance and everyone who saw them exclaimed at 
their beauty massed together, many taking them for lilies 
of the valley. The Goodyera pubescens was to be found 
in every woods, but the Calapogon and the delicate 
Pogonia ophioglossoides were onl^^ found in one locality 
although they grew plentilully in that one place. The 
Pogonia verticillata grew quite by itself and was only 
found on this one wooded bank. The modest Orchis 
spectabilis grew by a favorite stream, although one plant 
surprised us by making its appearance half wa3^ up an 
intensely steep hill. The Cypripedium acaule had not 
been found here for years but we discovered just one soli- 
tary specimen in a pine woods far from any habitation 
and the Cypripedium pubescens were found still later, 
farther yet from the haunts of men. The one twayblade 
was found so long after flowering that only another sea- 
son can determine its name. 
Then the H aben arias ; the H. tridentata was found 
growing beside every branch where it was protected from 
high water. H. virescens was only occasional, but H. 
clavellata was more common and H. lacera was some- 
times found. A most glorious sight was the little sphag- 
num bog covered with yellow fringed orchises which we 
found in July. H. ciliaris and H. cristata were growing 
side by side and the distinction between the two was plain
