Inventory

factory door/' as it is written in the Annals of Horti- 

 culture for 1891; wherefore we may compile an inventory 

 at the outset of vegetable-garden plants. The list is not 

 nearly complete for the countries of the world, but it con- 

 tains sufficient species for purposes of illustration, and it 

 includes all those grown to any extent in the United States 

 and Canada. The first obligation of the horticulturist is 

 .to know his plants and be able to grow them. 



If the reader is curious to compare this inventory with 

 a catalogue of species of fruits (as in Principles of Fruit- 

 Growing, 20th and subsequent editions) he will note the 

 marked dissimilarities in the representations of the fam- 

 lies of plants. The great Eose famil}^, so abundant in 

 pomological material, is practically unrepresented, whereas 

 the Pea family, barely represented in the fruits, is fertile 

 in important species. The Eue family (Eutaceas, yielding 

 the citrus fruits) is unrepresented, as also Myrtaceae, Vita- 

 ceae, Palmace^e, and the nut-yielding families as Juglan- 

 daceae and Fagaceae. On the other hand, certain families 

 come prolninently into this list that are absent from the 

 other, as Crucifer^, Chenopodiaceae, Umbelliferae, Labiatae, 

 Composite. The fruits and the vegetables represent unlike 

 parts of the plant kingdom, showing that there is a real 

 divergence between pomiculture and olericulture.
