A few plants liave anomaloUS leaves. Those of the Onion are fillforin. The Pitcher-Plant of our northern swamps has very curious leaves (Fig. 1G9), apparently formed by the turning in and cohesion of the outer edges of an ordinary leaf so as to form a tube, closed except at the top, and armed on the inner surface with bristles pointing towards the base of the leaf. 184. Finally, as leaves present an almost infinite variety in their forms, it will often be necessary in describing them to combine the terms explained above For instance, a leaf may not be exactly linear, nor exactly lance-shaped, but may approximate to both forms. In such a case the leaf is described as lance-linear, and so with other forms. The following form of schedule may be used with advantage in writing out descriptions of leaves. Two leaves — one of Maple and one of Sweet Brier — are described by way of illustration. If a leaf is compound, the particulars as to outline, margin, apex, base, and surface will have reference to the leaflets. The exercise-book prepared to accompany this work contains a supply of blank schedules for leaf-description, with space for drawings. I 1 .j , a;i i) ! ]r, '/ll i; i.\ •ft. III I f V 1.
