Geophilous Plants of Ohio, II. 
*33 
Gentiana andrewsii Griseb. An oblique rhizome, about 2 in. 
long, with numerous fleshy roots showing root contraction. 
Corallorhiza odontorhiza (Willd.) Nutt. A small bulb, sending 
out the coralloid roots from the base. 
Lespedeza frutescens ( L. ) Britton. A long woody tap root, 
surmounted by a close crown. 
Lespedeza procumbens Michx. A close crownformer. 
Lespedeza violacea (L.) Pars. A long tap-root and close 
crown, sending up from 10 to 20 annual shoots. 
Lespedeza hirta (L ) Ell. A crownformer. 
Meibomia pauciflora (Nutt.) Kuutze. A rhizomatous crown 
former. The rhizomes are slender, a foot or more in length, and 
branching. At the point of emergence there is usually a cluster 
of annual stems. 
Thalictrum purpurascens L. A crownformer. 
Coreopsis tripteria L. Rhizome composed of annual segments 
which are about 1 inch in length. 
Epigaea repens L- Rhizomes long and slender, close to the 
surface of the ground. 
Cypripedium acaule Ait. Rhizome 2 or 3 in. long, sending 
out numerous strong roots. The annual growth in length is 
very small. In one specimen examined the growth of four years 
amounted to only 6 lines. 
Waldsteinia fragarioides (Michx.) Tratt. Rhizome 4 to 12 
in. long, slender. Lateral branches numerous. 
Plantago cordata Lam. An oblique rhizome of unique habit. 
The rhizomes of large plants are yh to Jq in. thick, and are solid 
for 2 or 3 in., but back of this the center rots away, leaving a 
shell which splits up to the base. In small plants it splits but 
once, forming a flat or slightly incurved ribbon. This becomes 
rounded, and seems to perform the function of a root. It, 
however, dies off gradually at the posterior parts. In fig. 1 the 
split portion is still united near the middle of one of the specimens, 
and a portion of the posterior end is dead. The root-like portion 
of the rhizome is much longer than the true rhizome. 
Plantago rugellii Dec. A short, upright rhizome. 
Plantago major L. A short, upright rhizome. 
Lobelia syphilitica L. A close crownformer. 
Geum canadense Jacq. A short, horizontal rhizome. 
A specimen of the large Noctuid moth, Erebus odora Linn., 
was taken by members of the class in geology who were out for 
a field excursion on October 5th. So far as I am aware this is 
the first record for the capture of this species in Central Ohio. 
The specimen was said to be in excellent condition when taken, 
but was slightly rubbed and torn in bringing it in.
