 Rh as in Paris quadrifolia, t. 7, Polemonium cæruleum, t. 14, &c.

Ramea, branch-leaves, sometimes differ from those of the main stem, and then require to be distinguished from them, as Melampyrum arvense, t. 53.

Alterna, alternate leaves, stand solitarily on the stem or branches, spreading in different directions, as those of Borage, t. 36, and innumerable other plants.

Sparsa, scattered irregularly, as in Genista tinctoria, t. 44, Lilium cholcedonicum, ''Curt. Mag. t. 30, and bulbiferum, t.'' 36.

Opposita, opposite to each other, as Saxifraga oppositifolia, ''Engl. Bot. t. 9, Ballota nigra, t.'' 46, &c.

Conferta, clustered, or crowded together, as those of Trientalis europæa, t. 15.

Bina, only two upon a plant or stem, as in the Snowdrop, Galanthus nivalis, t. 19, Scilla bifolia, t. 24, and Convallaria majalis, t. 1035.

Terna, three together, as Verbena triphylla, ''Curt. Mag. t.'' 367. The plants of Chili and Peru seem particularly disposed to this arrangement of their leaves.
