APPENDIX II 153 



IV. Elms, Basswoods or Lindens, Indian Corn, and various 

 Grasses are good. But Iris, Hemerocallis (Day Lily), etc., 

 while showing the two ranks excellently, do not allow the 

 insertion of the leaves to be determined with sufficient 

 readiness. 



VII. Three-ranked arrangements are by no means com- 

 mon. Those who live in the eastern portions of the United 

 States may obtain the Veratrum in the spring, and no more 

 excellent object can be found. The upright shoots of Alders, 

 Hazels, and Beeches sometimes show it very distinctly, and 

 teachers who have not access to Veratnim should seek 

 suitable materials from these plants. 



VIII. The upright wand-like shoots, lighted equally or 

 nearly so from all sides, of young plants or of branches 

 from the roots or bases of the plants mentioned should be 

 used. Sumachs, Willows, and Oaks are excellent. Where 

 Willows have been pollarded, the adventitious vertical 

 branches which spring out make excellent objects, especially 

 in the case of the broader leaved S. discolor, S. cordata, 

 and S. lucida. 



IX. Read Kerner and Oliver, Volume I, Part i, p. 400, 

 for further cases. 



XI. Cones of Larch, Sequoia gigantea, Sugar Pine, etc., 

 are excellent. Read carefully the references to this subject 

 in Kerner and Oliver and in Gray, recommended above. 

 The numbering of the scales of cones is an excellent task for 

 students to perform outside of the laboratory. 



XIII, XIV. Read Kerner and Oliver, Volume I, Part 2, 

 pp. 414-417 and 419, 420, especially compare Figs. 106 

 and 109 ; Lubbock, Flowers, Fruits, and Leaves, pp. 

 108-111.
