present knowledge we are unwilling to attempt to classify, as those 
wherein the roots form a capillary mass from the base of the bulb, asin 
varieties of celeriac and rutabagas ; or those roots which are fascicled, » 
as in the sweet potato and skirret. 
If we apply to these divisions the methods of botany, we can group 
together the various results of similar selections in a form which admits 
of provisional classification as below: 7 
Cass, having reference to the portion used, or upon which selection 
has been exercised, as roots, bulbs, tubers, stems, leaves, foliage, 
fruits, ete. 
STAGES, corresponding in position to orders in botany, and includ- 
ing groups of selections within classes. 
SUB-STAGE, a division of stages. 
Forms, which correspond in position to botanical genera, and include 
groups within a stage of plants of similar outline of parts used. 
VARIETY, which corresponds to botanical species, and form the unit 
of the system proposed. 
We will illustrate by an example taken from roots. We will com- 
mence with an assumed order, as : — 
Crass 1. The roots the portion valued. 
Stace 1. The taper root, the bulbous or fleshy portion tapering 
to the fine root at the extremity. 
° 
Sus-staGe 1. The root elongated, very much longer than broad. 
Form 1. Slender, cylindrical or nearly so, often branching, 
the collar portion not distinct from the root. 
VARIETIES — to be described — gobo, horseradish, salsify, 
scolymus, scorzonera, etc. 
Form 2. Shaped like a cone, but distinctly rounded at top. 
—+ Growing nearly or quite wnder ground. 
VARIETINS to be described. — Crapaudine beet, White Sile-. 
sian beet, etc.; Madgeburg chicory ; Freneuse 
turnip, Morigny turnip, etc., Common Long 
parsnip; Tuberous rooted parsley; Long Scarlet 
radish; Wood’s Harly Frame radish, etc.; ram- 
pion. 
= Growing wholly or in part above ground. 
VARIETY to be described. — Long Yellow carrot. 
Form 8. Cone formed, flat or but slightly rounded, or hol- 
lowed at top, etc. 
Form 4. Terete: cylindrical and but slightly tapering, ete. 
Form 5. Cylindrical, but both ends ellipsoidal, etc. 
SUB-STAGE 2. The root bulbous, the vertical axis much longer 
° than the transverse. 
Form 1. Spindle shaped, etc. 
The other stages in class one might be stage two, the caudate or 
tailed ; the root proper starting abruptly from the flattish surface of
