RHODOPHYLLIS BLEPHARICARPA, Zar. 
Gen. Cuan. Frond flat, membranous, dichotomously or pinnately decom- 
pound, mostly margined with leafy or slender processes, and com- 
posed of two strata of cells ; the medullary stratum formed of roundish- 
angular cells, the cortical of coloured cellules in one or few rows. 
Fructification: 1, marginal, external conceptacles, containing within 
a pericarp formed of radiating filaments, a compound nucleus, formed 
of bundles of spore-threads radiating from a basal (or central) pla- 
centa; 2, zonate ¢e¢raspores, immersed in the peripheric cells of the 
segments or marginal processes. —RHoDOPHYLLIs (Kiitz.), from podeos, 
red, and duAXor, a leaf. 
Frons plana, membranacea, dichotome v. pinnatim decomposita, segmentisque 
ciliisve marginalibus obsita, stratis duobus conteata ; strato medullari cellulis 
rotundato-angulatis, corticali cellulis coloratis uni- v. pauci-seriatis composito. 
Fruct.: 1, cystocarpia marginalia, externa, pericarpio jilis moniliformibus 
radiantibus conflato munita, nucleum compositum ex fasciculis filorum radian- 
tium formatum foventia ; filis demum in sporas solutis ; 2, tetraspore zonatim 
divise, fronde v. lacinulis marginalibus immerse. 
Ruopopxytuis Jepharicarpa ; frond membranaceous, subdichotomous or 
irregularly multifid ; lacinie linear, spreading, obtuse, fringed through- 
out with minute processes; cystocarps and tetraspores both formed in 
the marginal processes. 
R. blepharicarpa ; fronde membranacea subdichotoma v. vage multifida, laciniis 
lato-linearibus patentibus obtusis margine ciliato-fimbriatis, cystocarptis tetra- 
sporisque in cilis marginalibus evolutis.

Descr. Root discoid. Frond 4-5 inches long and as much in expansion, divided 
from the base into several segments, which are repeatedly subdivided in an 
irregularly dichotomous or alternate manner. Lacinie@ nearly linear, 3-5 
lines in breadth, nearly of uniform width in each specimen, obtuse, or the 
extremities bifid, in most cases fringed with short, filiform, or awl-shaped 
ciliary processes. Fructification of both kinds formed in the cilia. Concep-
