Description. — The adult symmetrical stock consists of rose-like clusters of spirally coiled 

 leaves, each leaf forming part of a sharp cone and making an angle of about 45 degrees with 

 the horizon. The leaves are thin at the edge and frequently longitudinally wrinkled. No 

 epitheca is visible at this stage. 



The calicles average about • 75 mm. across, with six thin primaries well developed, 

 secondaries rudimentary. The apertures are sometimes conspicuous, sometimes obscured by the 

 tubercles. They are mostly protuberant, that is, surrounded by rings of tubercles within which 

 they rise, the septal spines projecting from the tubercles. On the under surface the calicles 

 are numerous and ii-regularly protuberant so that the surface looks rough. 



The coenenchyma consists of a dense laminate streaming layer which forms a thin but 

 dense, almost stony under surface to the leaves ; through this the calicles protrude. On the

 doubtless because of Pallas' commendation, from Turgot's Mem. Instr., pi. xxiii.
