TANGIBLE MEMORIES: Californians and their Gardens, 1800-1950, by Judith M. Taylor and Harry Morton Butterfield

STRANGE PLANTS of THE SEAS: Illustrationes algarum in itinere, by Aleksandr Postels and Franz Ruprecht

"Leaving out of consideration the more exact methods of classification employed by algologists, algae may be divided into their four great botanical sub-classes on the basis of color, although this method of identification is not always correct. The blue-green or purple sea-weeds are all small — mostly microscopic — with two genera consisting of fine, hair-like, filamentous plants. The grass-green algae are among the most widely diffused of plant forms, being found everywhere between tide marks, floating on the surface of the deep sea, covering damp earth, walls, palings and tree trunks, sticking to the surface of leaves in damp forests and existing in every brook, river, ditch, pond or casual pool of rain water. Many are microscopic in size, but others are quite large, resembling grass, leaves, mushrooms and a multitude of other common land plants."

By conservative estimate the tree was at least sixty feet high, its general shape and proportion extremely graceful. Four feet above the ground the trunk measured twenty feet in circumference, and at a height of fifteen or twenty feet, it divided into several large branches which spread over an area some 200 feet in diameter."
