Chart 269.—Distribution of algse on Spindle Rocks, May 22, 1905. The rocks at this date presented a characteristic algal flora of the spring at its full development. There was not much change in the species since April 22 (chart 268), but a large increase in the quantity of vegetation. Cladophora lanosa var. uncialis (11) was still the dominant green alga, but Enteromorpha iniestinalis (7) had begun to appear; these two species extended the green zone much higher up on the rocks than where it was a month previous (chart 268). The brown zone at low-water mark (the dotted line) and just below, composed chiefly of Ectocarpus penicillatus (18), Phyllitis fascia (24), Scytosiphon lomenlarius (26), and Chordaria flagelliformis (28), was also broader and more evident. Polysiphonia urceolata (47) formed a conspicuous red zone below the brown, with extensive growths of Chondrus crispus (49) extending into deeper water. List of species: Enteromorpha intestinalis, 7, young plants; Cladophora lanosa var. uncialis, n, abundant; Ectocarpusfasciculatus, 15, abundant on larger algae; Ectocarpus penicillatus, 18, abundanton larger alga; Sorocarpus uvceformis, 21, few on mussel shells; Desmotrichum balticum, 22, few mixed with Scytosiphon; Desmotrichum undulalum, 23, few mixed with Scytosiphon; Phyllitis fascia, 24, very abun- dant; Punctaria planiaginea, 25, few; Scytosiphon lomentarius, 26, abundant; Desmarestia viridis, 27, very abundant; Chordaria flagelliformis, 28, much; Chorda lomeniosa, 32, abundant; Laminaria Agardhii, 33; Ceramium rubrum, 43, abundant; Polysiphonia urceolata, 47, abundant; Polysiphonia violacea, 48, few; Chondrus crispus, 49, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may
