ANALYSIS OF THE NATURAL ORDERS, 



FOUNDED UPON THE MOST OBVIOUS OR ARTIFICIAL CHARACTERS, DE- 

 SIGNED AS A KEY FOR THE READY DETERMINATION OF ANY PLANT, 

 NATIVE, NATURALIZED OR CULTIVATED, GROWING WITHIN 

 THE LIMITS OF THIS FLORA. 



PROVINCES, CLASSES AND COHORTS. 



SUB-KINGDOM I. Phaenogamia or Flowering Plants. (PROVINCE.) 

 PROVINCE 1. Bark, wood and pith distinct, the two former 

 as concentric layers around the latter. Leaces net-veined. 

 Fvower, at least, never completely Z-mcr&us, its parts mostly 



in 4s and 5s. DICOTYLEDONS or EXOGEXS. (CLASS.) 



CLASS 1. Flowers with Btifjtnas, and pistils enclosing the 

 ovules, becoming seed-vessels enclosing the seeds. AXGIOSPERMS. (COHORT.) 

 COHORT 1. Corolla with the petals distinct. POLYPETALOUS. (A) 



COHORT 2. Corolla with the petals united. GAMOPETALOUS. (B) 



COHORT 3. Corolla (and often the calyx, also,) wanting. APETALOUS. (C) 

 CLASS 2. Flowers with open scales instead of pistils (or no 

 pistils at all), the ovules naked. (Pine, Cedar, Fir, Yew, 



Cypress, etc.) GYMXOSPERMS. (COHORT.) 



COHORT 4. The cone-bearing plants (same as Class 2). COXQIDEJ5. (D) 



PROVINCE 2. Bark, wood and pith commingled. Lcs.parallel- 



veined (rarely netted). Fls. t-mcrouj. MONOCOTYLEDONS or ENDOGENS." 

 CLASS 3. Fls. with no glumes. PET ALIFER.E or AGLUMACEOUS. (COHORT.) 

 COHORT 5. Fls. on a spadix, apetalous or incomplete. SPADICIFLOR^E. (E) 

 COHOBT 6. Flowers complete, with a double perianth. FLORIDE^E. (F) 



CLASS 4. Flowers invested with green, alternate glumes 

 instead of the perianth which is wr.nting or minute. GLUMIFER^E. (ConouT .

 PROVINCE 1. With stem and leaves distinguishable, and 



containing woody tissue and vessels. ACROGEXS or AXGIOSPOR^E. (Hi
