 LESSON XII. THE FLOWER : ITS PARTS OR ORGANS p. 84. 



223. The Flower. 224. Its nature and use. 225. Its organs. 226. The 

 Floral Envelopes or leaves of the flower.. Calyx and Corolla, together called 

 (227) Perianth. 228. Petals, Sepals. 229. Neutral and "double" flowers, 

 those destitute of, 230. The Essential Organs : Stamens and Pistils. 231,232. 

 The parts of the flower in their sue cession. 233. The Stamen : its parts. 234. 

 The Pistil : its parts. 



LESSON XIII. THE PLAN or THE FLOWER p. 88. 



235. Flowers all constructed upon the same plan. 236. Plan in vegetation 

 referred to. 237 - 239. Typical or pattern flowers illustrated, those at once 

 perfect, complete, regular, and symmetrical. 241. Imperfect or separated flowers. 

 242. Incomplete flowers. 243. Symmetry and regularity. 244. Irregular flow- 

 ers. 245. Unsymmetrical flowers. 246. Numerical plan of the flower. 247. 

 Alternation of the successive parts. 248. Occasional obliteration of certain parts. 

 24f*- Abortive organs. 250. Multiplication of parts. 



LESSON XIV. MORPHOLOGY OF THE FLOWER p 96. 



251. Recapitulation of the varied forms under which stems and leaves appear. 

 252. These may be called metamorphoses. 253. Flowers are altered branches ; 

 how shown. 254. Their position the same as that occupied by buds. 255, 

 256. Leaves of the blossom are really leaves. 257. Stamens a different modifi- 

 cation of the same. 258. Pistils another modification ; the botanist's idea of 

 a pistil. 259. The arrangement of the parts of a flower answers to that of the 

 leaves on a branch. 



LESSON XV. MORPHOLOGY OF THE CALYX AND COROLLA. . . p. 99. 



260. The leaves of the blossom viewed as to the various shapes they assume ; 

 as, 261. by growing together. 262. Union or cohesion of parts of the same sort, 

 rendering the flower, 263. Monopetalous or monoscpalous ; various shapes de- 

 fined and named. 265 The tube, and the border or limb. 266. The claw 

 and the blade, or lamina of a separate petal, &c. 267. When the parts are 

 distinct, polyscpalous, and polypetalons. 268. Consolidation, or the growing 

 together of the parts of different sets. 269. Insertion, what it means, and what 

 is meant by the terms Free and Hypogynous. 270. Perigynous insertion. 271, 

 272. Coherent or adherent calyx, &c. 273. Epigynous. 274. Irregularity of 

 parts. 275. Papilionaceous flower, and its parts. 276. Labiate or bilabiate 

 flowers. 277, 278. Ligulate flowers : the so-called compound flowers.
