Inventory 3 



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 

 incliides 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 curio\is 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 family, 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 (Eutaceee, yielding 

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

 cese, Palmaceae, and the nut-yielding families as Juglan- 

 daceae and Fagacese. On the other hand, certain families 

 come prominently into this list that are absent from the 

 other, as Cruciferae, Chenopodiacese, UmbelliferaB, Labiatae, 

 Compositse. The fruits and the vegetables represent unlike 

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

 divergence between pomiculture and olericulture.
