interesting islands; in many ways of more interest than larger 

 areas. Waterfowl no doubt spread these plants so that nothing 

 can be deduced perhaps from its presence as to the connection 

 of the plant origin with the lands to the south or north of the

A New Orchid from Louisiana 



A Specimen of Epidendrwn conopseiim Ait. was found 

 growing on the bark of a live oak tree, Quercus virginiana, 

 at Greenwood Plantation, West Feliciana Parish, Louisiana. 

 The orchid was noted for the first time during the summer 

 of 1927 by Mrs. Edward Butler. A specimen was collected in 

 August 1928 by Minna F. Koch, and deposited in the her- 

 barium of Cornell University. This is the first time that 

 Epidendriim conopseiim has been reported from Louisiana, 

 and it extends the range of this species westward.

 pared to present a "convenient means of identifying the plants 

 of Ohio .... from fresh material gathered in the field." 



All the species of Pteridophyta and Spermatophyta known 

 from Ohio are given. The keys are the important feature of 

 the book. They are quite detailed, so much so that the author 

 has felt it unnecessary to give any descriptions of the families 

 or species and only gives them for the genera as a check for 

 the user of the keys. For the Equisetums keys are given that 

 can be used with either fertile or sterile shoots. For one fairly 

 well aquainted with technical botanical terms the keys are 

 very clear and easily used, but for one not familiar with such 

 terms the book may well seem discouraging. Of course there
