Geophilous Plants of Ohio, II. 133 



Gentiana andrewsii Griseb. An oblique rhizome, about 2 in. 

 long, with numerous fleshy roots showing root contraction. 



Corallorhizaodontorhiza (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. 



lycspedeza procumbens Michx. A close crownformer. 



lyCspedeza 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.) Kuntze. 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 i inch in length. 



Epigaea repens E- 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 3'ears 

 amounted to only 6 lines. 



Waldsteinia fragarioides (Michx.) Tratt. Rhizome 4 to 12 

 in. long, slender. Lateral branches numerous. 



Plantago cordata Eam. An oblique rhizome of unique habit. 

 The rhizomes of large plants are }4 to 34 iu. 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. i 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 E. A short, upright rhizome. 



Eobelia syphilitica E. A close crownformer. 



Geum canadense Jacq. A short, horizontal rhizome. 



A specimen of the large Noctuid moth, Erebus odora Einn., 

 was taken by members of the class in geolog}' 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.
