No other crop approaches grass in importance, and yet in many parts of the country no other crop is so little studied. A good deal of attention has been devoted in the following pages to the means of recognising the various grasses, as it is considered that the ability to recognise the different varieties is the surest way to induce a study of their habits and capabilities. On this study depends the solution of the most important of all problems facing the New Zealand farmer, namely: ‘‘ What is the best grass mixture to sow on my land?” F.W.H. LIncoLy, 1918. CHapP.

The majority of the pastures in New Zealand will be found clothed with only some four or five grasses, but in exceptional circumstances some dozen additional species may be found. It is the design of this chapter to describe these grasses so that they may be recognised and named, to discuss their value as fodder, and their suitability to different classes of soils. In the description of a grass, the leafage is of most im- portance because that is to be found all the year round, while the flowers can be found for only a short period. The following terms are used in describing the leafy portion of a grass :—The sheath is the part in which all the leaves are folded together to make a kind of a stem from which the blades of the leaf spring. The ligule is a transparent mem- branous flap standing up at the junction of the sheath and the blade. Its presence or absence and its shape when present are very important points in identifying grasses. It can be very plainly seen in Cocksfoot and Prairie Grass for example. The ears are a pair of hooked Fig. 1.—A: Base of blade. B: Ligule.

They are very well developed in barley. A rhizome is an underground creeping stem, giving off roots downwards and frequently leaves upwards at 6 PASTURE PLANTS AND PASTURES OF N.Z. each knot. All grasses with rhizomes are called ‘‘ Twitches.’’ A stolon is an overground creeping stem rooting where the knots touch the ground. A common example is found in the Strawberry, and among grasses, stolons are often found in Creeping Bent.
