Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1903 edition. Excerpt: ...in inner leaves. The inner perichaetial leaves are said to be shorter than the outer, and Sullivant says the leaves lack the plicae of P. fontana. BARTRAMIA Hedw. The Bartramias grow in moist niches in cliffs and on moist shady banks, looking much like tufts of green wool. Their capsules are globular and somewhat unsymmetric when moist, but dry with regular folds and alternate ridges. When very dry the body of the capsule becomes so shrunken as to be smaller than the mouth of the capsule itself. The leaves are long and slender and somewhat curled when dry, and strongly papillose. B. CEderi is somewhat of an exception as regards leaf characters, and by recent writers is put in the genus Plagiopus. Kcy 1. Leaves lanceolate, not papillose....................... CEderi. Leaves nearly linear, very long and narrow, papillose.............. 2. 2. Leaves from a sheathing scarious base.................... ithyphylla. Leaves without sheathing base....................... pomiformis. B. pomiformis (L.) Hedw. is often known as the Apple Moss. It is a common and beautiful plant, 2-7cm in height. The leaves are long linear lanceolate, 4.5mm long, somewhat crisped when dry, papillose and serrate, with margins recurved; costa excurrent; autoicous or synoicous; spores in April or early May. B. CEderi (Gunn.) Swtz. 1s a smaller, less common plant of cool, moist ravines. The leaves are much shorter, lanceolate, not crisped when dry, not papillose, margins sharply serrate and widely revolute most of the way; spores two or three weeks later than in B. pomiformis. The leaves of this species and also of B. pomiformis are serrate on the roll, or apparent edge, of Figure 104. a. Bartramia pomiformis x the revolute margin.
