English: Plate 3.
Figs. 1-8. Sphacelaria mexicana. Figs. 1-3, propagulae on their supporting branches, showing the two short arms and the stalk articulation. Fig. 4, a propagulum on a branch viewed from the lower margin. Figs. 5, 6, two detached propagulae showing progressive elongation of the arms in germination. Fig. 7, a detached propagulum viewed obliquely from below. Fig. 8, a portion of a filament apparently showing two empty sporangia, x 155. Is. Reviiia Gigedo. [= syn. of Sphacelaria tribuloides Meneghini, AlgaeBase]
Figs. 9-16. Carpomitra luxurians. Figs. 9, 10, branched paraphyses with expanded end cells. Figs. 11-16, paraphyses with sporangia in various stages of development, and empty sporangial sacs, x 330. I. Santa Maria. [=syn. of Carpomitra costata (Stackhouse) Batters, AlgaeBase]
Figs. 17-21. Spermothamnion phycophilum. Fig. 17, a small portion of a basal filament with haptera and three erect filaments. Fig. 18, upper part of a tetrasporangial filament to show unilateral seriate sporangia, and the progressive development of branched sporangial clusters. Figs. 19, 20, portions of older filaments to show well-developed sporangial clusters. Fig. 21, tip of a male filament to show unilateral seriate spermatangial clusters; the forked character is unusual, and the series are usually longer, on a simple filament, x 70. I. Santa Maria. (=syn. of Tiffaniella phycophila (W.R.Taylor) E.M.Gordon, AlgaeBase]
