OBSERVATIONS. 



The following key contains the species of algae which I have found 

 during the period of two years devoted to the collection of data for this 

 report. The list has been prepared in a key form so as to be an aid to 

 those who do not have access to the literature on algae. 



MYXOPHYCE^, sometimes called Cyanophycese, or Schizophyceie, 

 are commonly called the Blue-Green Algae because of their typically 

 blue-green color. Plants one or many celled, often associated together 

 into families in the form of filaments, spherical or regular gelatinous 

 masses. Some forms endowed with a peculiar motion. Plants found in 

 aerial situations, as endophytes, on rocks, trees, and tanks, especially in 

 fresh, brackish, or salt water, in hot springs and mineral springs. 



Key to the Orders of Myxophycese. 



\. Plants unicellular, single or associated in families or colonies, com- 

 monly surrounded by copious gelatinous integument, rarely forming 



filaments Coccogonese. 



II. Plants multicellular, filamentous, filaments simple or branched, gen- 

 erally consisting of one or more cells within a sheath, attached to a 

 substratum or free-floating Hormogonese. 



Order L COCCOGONE^. 



Key to the Families of Coccogonese. 



L Plants epiphytic, often differentiated into basal and apical regions; 



reproduction by means of nonmotile gonidia Chanisesiphonacese. 



W. Plants very rarely epiphytic, not differentiated into basal and apical 

 regions; reproduction by vegetative division of cells in 1, 2, or 3 

 directions Chroococcacese. 



Family L CHAMiESIPHONACE^E. 



None of the species belonging to this family have been found in the 

 citv water reservoirs.
