Subfamily Sarcomenieae Schmitz. 
CONSPECTUS OF THE GENERA. 
A. — Frond continuous, nowhere forming a network. 
a. Sori scattered over the main frond Caloglossa 
Harvey. 
b. Sori in simple foliolae, prolificating from the 
frond. 
1. Foliolae fronded in the margin Sarcomenia 
Sonder. 
2. Foliolae from the midrib as in Hypo- 
glossum . Sonderella 
Schmitz. 
B. — Frond forming a network. 
1. Feather-shaped, the meshes of the web of the 
plume rectangular . . Claudea 
Lamouroux. 
CALOGLOSSA Harvey. 
Frond small, flat, dichotomous, midribbed, with a transverse series of 
cells, and folioles springing from the midrib, as in Hypoglossum. Cysto- 
carps sessile on the midrib. Tetrasporangia in linear series from midrib to 
margin, triangularly divided. 
Caloglossa Leprieurii (Mont.) J. Agardh. 
Segments linear-lanceolate, constricted in joints. Frond to 5 cm. high, to 
2 mm. broad. Tetrasporangia in parallel transverse lines. Colour violet. 
Attached to rocks or piles by rootlets creeping beneath the dichotomies, 
often growing at or above high water mark. 
New South Wales, Tasmania, and Victoria in the estuaries. 
SARCOMENIA Sonder. 
Frond broad or narrow, branching by intra-marginal prolifications. The 
structure of the frond is peculiar, with four pericentral syphon tubes, 
bordered on each side by two marginal syphons of half the length of the 
others and set end to end. Cystocarps obovate-globose, pedicellate. 
Folioles (stichidia) bearing tetrasporangia, these arranged in opposite pairs 
in two parallel rows. Colour when living light-fawn, becoming bright rosy- 
red in fresh water. Substance rapidly decomposing in fresh water. 
A. — E corticate, the whole structure polysiphonious. 
1. Hemispherical masses, to 5 cm. across, formed 
of fine gelatinous threads, of a beautiful 
cinnabar red S. miniata (Ag.)
