Note 5 — Suggestions on the Use of Colors in Mats.

Pandans or “screw-pines,” as they are sometimes called, are readily recognized by their characteristic appearance.5 The common forms occasionally planted in pots as house plants and in gardens, or more often found growing wild, have long and rather narrow leaves always supplied with more or less sharp spines which run along both their margins to the very tip. Another row of spines is present on the under surface along the midrib. Bearing in mind this middle row of spines it is impossible to mistake the leaf of the pandan for that of the pineapple or maguey, which it resembles more or less in form and shape. Another very prominent feature of pandans is the presence of air or prop roots which grow from the stem above the ground and are helpful to the plant in various ways. The veins of the leaves always run parallel and in a longitudinal direction. The leaves are never borne on a petiole, but are attached directly, in winding corkscrew fashion, in ranks of three, to the stem.
