Three Keys to Plants in the Torrey Club range 1 



This booklet deserves a warm welcome by all those of our 

 region interested in wild flowers. Covering the area of the Tor- 

 rey Botanical Club, the keys make use of easily recognized 

 characters, such as color, shape and leaf arrangement. Groups 

 that have proved particularly difficult are taken. The first key, 

 to submerged and floating aquatic plants includes water lilies, 

 duck weed, Potamogetons, Utricularias and others. The second 

 key includes the fall flowering monocotyledons, exclusive of 

 grasses and sedges. The third includes all the flowering compos- 

 ites. This last has 12 sub-keys, under such heads as — compos- 

 ites with spiny or prickly leaves; unarmed composites with disk 

 flowers and white rays; white asters; blue purple and pink as- 

 ters; unarmed composites with disk flowers and yellow orange or 

 brown rays; bidens; goldenrods; eupatoriums; unarmed com- 

 posited with drooping heads of ray flowers. 



With the key it is a simple matter to determine any of the 

 composites, goldenrods, asters or others that have been difficult 

 with the manuals, because of the much greater number of spe- 

 cies found in the wide range covered. Of asters, 30 species are 

 given and about as many goldenrods, which include all those re- 

 ported from our region. The pamphlet can easily be placed in a 

 pocket or handbag and determinations quickly made in the 

 field. A complete glossary and an index which gives the common 

 as well as the scientific names of all the plants complete the 

 book. 



In preparing the keys Miss Barrett made use of the local 

 herbarium at the Bronx Botanical Garden, of Norman Taylor's 

 "Flora of the Vicinity of New York" and of the regular manuals.
