NOTE

The student should have some idea of the terms genus, species and variety, although they are not capable of exact definition.

A species, or kind, is in botany the unit of classification. It embraces all such individuals as may have originated in a common stock. Such individuals bear an essential resemblance to each other, as well as to their common parent in all their parts. E.g., the Cinnamon fern is a kind or species of fern with the fronds evidently of one kind, and of a common origin, and all producing individuals of their own kind by their spores or rootstocks. When such individuals differ perceptibly from the type in the shape of the pinnæ, or the cutting of the fronds, we have varieties as frondòsum, incìsum, etc. Or if the difference is less striking the word form is used instead of variety, but in any given case opinions may differ in respect to the more fitting term.

A genus is an assemblage of species closely related to each other, and having more points of resemblance than of difference; e.g., the royal fern, the cinnamon fern, and the interrupted fern are alike in having similar spore cases borne in a somewhat similar manner on the fronds, and forming the genus Osmunda. In like manner certain members of the clover group--red, white, yellow, etc., make up the genus Trifolium.

Thus individuals are grouped into species and species are associated into genera, and the two groups are united to give each fern or plant its true name, the generic name being qualified by that of the species; as in the cinnamon fern Osmúnda (genus), cinnamòmea (species).

THE PETRIFIED FERN

  In a valley, centuries ago,
  Grew a little fern-leaf green and slender,
  Veining delicate and fibers tender,
  Waving when the wind crept down so low;
  Rushes tall and moss and grass grew round it,
  Playful sunbeams darted in and found it,
  Drops of dew stole down by night and crowned it.
  But no foot of man e'er came that way--
  Earth was young and keeping holiday.

  Monster fishes swam the silent main,
  Stately forests waved their giant branches,
  Mountains hurled their snowy avalanches,
  Mammoth creatures stalked across the plain,
  Nature reveled in grand mysteries;
  But the little fern was not of these,
  Did not slumber with the hills and trees,
  Only grew and waved its wild, sweet way;
  No one came to note it day by day.

  Earth, one time, put on a frolic mood,
  Heaved the rocks and changed the mighty motion
  Of the deep, strong currents of the ocean;
  Moved the plain and shook the haughty wood,
  Crushed the little fern in soft, moist clay,
  Covered it and hid it safe away.
  Oh, the long, long centuries since that day!
  Oh, the changes! Oh, life's bitter cost!
  Since the useless little fern was lost.

  Useless? Lost? There came a thoughtful man
  Searching Nature's secrets far and deep;
  From a fissure in a rocky steep
  He withdrew a stone o'er which there ran
  Fairy pencilings, a quaint design,
  Leafage, veining, fibers clear and fine,
  And the fern's life lay in every line!
  So, I think, God hides some souls away,
  Sweetly to surprise us the last day!--M.B. BRANCH.
