Botany 



102. Crypiogamic Botany. — This course is designed to familiar- 

 ize the student with the salient morphological characteristics of the 

 green algae, bryophytes, and pteridophytes, and with their taxo- 

 onomic and economic relations as exemplified by the region in the 

 vicinity of Douglas Lake. Special attention will be given to the dis- 

 tributional peculiarities of various forms and to the method of iden- 

 tifying these, both in the laboratory and in the field. 



Saturday. Two hours credit. Assistant Professor Nichols. 



Prerequisite : A course in elementary collegiate botany. 



This course gives one hour of credit to graduate students. Stu- 

 dents wishing two hours graduate credit must perform additional 

 work and will register for Course 102a. 



102b, Taxonomy of the Bryophytes. — A course primarily sup- 

 plemental to the course on the green cryptograms and concerned 

 largely with the systematic study of the mosses and the liverworts. 

 So far as the time permits, the species growing within reach of the 

 camp will be collected and identified. 



Tuesday. Two hours credit. Assistant Professor Nichols. 



Prerequisites : Open to those who are taking course 102, or 

 who have had work on the bryophytes equivalent to that given in 

 that course. 



This course gives one hour of credit to graduate students. Stu- 

 dents wishing two hours of credit must perform additional work and 

 will register for course I02<:. 



104. Systematic Botany. — The chief aim of this course is to 

 acquaint the student with the flora about the Station and to give 

 him facility in the identification of plants by the Manual. About 

 one hundred species of plants are identified in the field, the char- 

 acteristics of the more important families of flowering plants are 

 learned, and the general principles of the classification of plants are 

 presented. There is excellent opportunity for the collection and prep- 

 aration of material for an herbarium. Students who complete this 

 course successfully should be able to identify readily the native flora 

 in any section of the country.
