    The simplest cyanobacteria grow as single cells, which may be enclosed by a sheath or gelatinous envelope or may be clustered into colonies. Cell sizes range from 50 μm in length (e.g., Cyanothece, specialized cells in a cluster).Cells vary in form: spheres, rods, oval, fusiform, and irregular. The largest of our mosses are contained in the next genus, viz. Polyt´richum, some of them having the stems from 2 to 4 inches, or even more, in height; they are common on heaths and in woods. Polyt´richum pilif´erum (Pl. III. fig. 22) is very common on open dry heaths. This moss has simple stems, with the leaves crowded on the lower part of.

    VEGETABLE KINGDOM. 2 There is one peculiar factor which enters into the problem of the classification of plants and materially adds to its is the polymorphism of the individual: that is, the life-history is usually complex, the individual assuming different forms in various stages of its life-history. In a similar manner the spirally-marked tubes that are mingled with the seeds of the Hepatic Mosses are converted into elastic spiral threads (Fig. 85). So, also, the delicate cells or hairs that invest the coat of some seeds, which contain a spirally-coiled thread, give way when moistened, or are torn asunder by the force with Which the thread.

    An investigation of selected taxa of Staurastrum and Staurodesmus (Desmidiaceae, Desmidiales, Chlorophyta) was undertaken to help clarify their taxonomy. The study was conducted on samples collected in the lower Fraser Valley (British Columbia). Sampling was done over a 2 1/2 year period in four main lakes (Jacobs, Munday, Lost and Como Lakes) with physico-chemical analyses (pH, .   Stems and leaves of mosses were wonderfully distinct in structure, so much so that I could draw every cell. I even readily detected confervoid filaments, with cells arranged in linear series, resembling species now found in our waters. Numerous black bodies, probably spores of the mosses, were found in abundance.

This text presents the subject using a systems approach and is therefore a departure from the more commonly employed phyletic approach.

Topics covered include classification, cellular and sub-cellular organization, morphology and growth, reproduction and life cycles, evolution, phylogeny, physiology, ecology and the relationship between algae and man. Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America.

Cooke says of this genus that it is scarcely so well characterized as many with which it is associated, and that some of the species are evidently so closely allied to some of the species of the genus Geoglossum that it is difficult to draw the line of demarcation between them, particularly so with the species Mitrula pistillaris B.

Current classification of freshwater members of the Phaeophyceae is therefore still largely based on morphological and reproductive structures: growth habit, branching pattern, plastid shape and number, and type of sporangia (Wehr,Eloranta et al., ).However, efforts have been made to reconcile morphological and cytological data with molecular information (McCauley and Wehr, ).

Taxonomic classification: Algae belong to at least 10 different taxonomic divisions (a division in plant taxonomy is equivalent to a phylum in zoological classification).Classification is based on four major considerations: (1) pigmentation (kinds and quantities; see Chapter 12), (2) internal storage products (chemistry and structure), (3) cell wall (chemistry and structure), and (4.The chlorophyte Cladophora (Chlorophyta, Ulvophyceae; more than species) is widely regarded as the most important harmful filamentous alga of inland waters, and the most abundant alga in alkaline streams throughout the world (Table 2, Figure 9).It also thrives in many freshwater and brackish lakes, and among the most famous of its habitats are the Laurentian Great Lakes.
