/Iq/a. o^Aamn /¿> n eo/f/'/isi/ Jpo/f/e, ^.Ihnb'o*. Annotated by Nilda E. Aponte 698. Callithamnion Halliae Collins ms. Washed ashore, Key West, Florida. MRS. G. A. HALL. Frond up to 5 cm. high, usually with a percurrent axis, straight below, becoming flexuous near the top, up to .2 mm in diameter at the base, not corticated, with similar alternate branches; these sometimes bear- ing a second series; the next series of branches dividing dichotomously, at first at wide angles; the subsequent forkings less and less patent, ultimate divisions of one to several cells, from .01 to .02 mm. diam., not much tapering, end * slightly rounded, without terminal hair. Cells throughout the frond usually about 4 times as long as broad, but where the forkings are very dense, 1 to 2 times as long. Cystocarps depressed spherical, not distinctly lobed, single or several together, situated in the forking of a lateral branch, or on the side of a main filament. Antheridia forming tufts on the upper side of the ultimate ramuli, occurring on the same individual as the cystocarps. Tetraspores tripartite, occasionally cruciate, pyriform, sessile on the upper side of the ultimate ramuli, often one on each joint. Color a pale to a deep rose. This species presents quite a difference in habit, according as the alternate or the dichotomous system of branching is most developed, and as the latter is more or less dense. The two extreme forms resemble respectively C. Baileyi and C: corymbosum; its nearest affinity would seem to be with C. corymbosum. It adheres well to paper. 02348527
