remain for a time. It is then termed persistent. The: 

 gum-trees in general have a persistent calyx (flower-cup). 



Compare the various parts of the native Fuchsia or Correa 

 with those of the true Fuchsia : — 



NATIVE FUCHSIA 

 (CORREA). 



(Plate IV. p. 36.) 



Calyx (ca). — Cup-shaped, entire, 



monosepalous, green. 

 Corolla {co). — Four short petals, 



united into a tube for nearly all 



its length. 

 Stamens (S). — Eight, free at the 



bottom of the corolla. 

 Pistil [P). — Stigma very finely 



pointed, scarcely perceptible. 

 Disk (d). — Below the ovary. 

 Ovary (0). — Superior (above). 

 Leaf. — Cordate, margin entire. 

 Stem. — Rough. 



TRUE FUCHSIA. 

 (Plate V. p. 37.) 



Calyx (ca). — Cleft, polysepalous 



{many sepals), coloured. 

 Corolla (co). — Four long petals, 



distinctly divided. 

 Stamens (S). — Eight, inserted in 



the neck of the calyx (fiower- 



cup). 

 Pistil (P). — Stigma broad-shaped, 



very perceptible. 

 Disk (d). — Above the ovary. 

 Ovary (0). — Inferior (below). 

 Leaf. — Dentate, margin slightly 



toothed. 

 Stem. — Smooth. 



These botanical comparisons will serve to show the 

 inaccuracy with which common names are sometimes given 

 to plants. 



Further examples of superior and inferior flowers and 

 fruits will be found on contrasting the order Amaryllideae — 

 jonquil, snowflake, daffodil, etc. — with the order Liliaceae, 

 such as fringe-lily, tulip, true lilies (L^lium). The former 

 have an inferior calyx, the latter the reverse. 



LESSON VII. 



FRUITS. 



A fruit, botanically speaking, generally consists of two 

 parts, the pericarp or seed-vessel (covering of the fruit) , and
