Subfamily Tylocarpeae Kutzing. 
The genus Stenogramme Harvey is the only Australian genus. 
STENOGRAMME Harvey. 
Frond rose-red, flat, membranous, nerveless, flabellately laciniate, com- 
posed of two strata of cells, the medullary of roundish-angular cells in 
several layers, the cortical of minute coloured cellules. The cystocarps are 
linear, midrib-like, and .contain within a thick pericarp confluent masses 
of minute spores. The sori of tetrasporangia scattered in blotches over both 
surfaces of the frond, and ultimately changed into strings of cruciate 
tetrasporangia in linear series. Both forms of reproduction are unique. 
Stenogramme interrupt*! (C. Agardh) Montague. 
Frond flabelliform. Height 15 cm. to 30 cm. The lines of cystocarps 
interrupted in each lobe of the frond, sometimes 5 cm. long. 
The Atlantic and Pacific, New Zealand, Tasmania, and Australia (St. 
Vincent Gulf).
