KALLYMENIA CRIBROSA, Haw. 



Gen. Char. Frond carnoso-membranaceous, flat, oi" irregular shape, com- 

 posed of three strata ; the medullary stratum of interwoven and ana- 

 stomosing filaments ; the intermediate of large, roundish cells ; the 

 cortical of minute, vertically seriated cellules. Fructification: 1, 

 cystocarps sunk in the frond, but prominent to one or both surfaces, 

 containing a compound nucleus, formed of several nucleoli or masses 

 of spores ; 2, cruciate tetraspores, scattered among the cortical cel- 

 lules. — Kallymenia (/. Ag.), from KaWfi, heautiful, and viir]v, a 

 membrane. 



Frons carnoso-memhranacea, plana, amorpJia, stratis tribus cordexta. Stratum 

 meduUare ex fills ■hdertextis anaslomomntihus ; intermedium ex cellidis magnis 

 rotundato-angutatis ; corticate cellnlis minimis coloratis verticaliter seriaiis. 

 Friict. : 1, cystocarpia fro7idi immersa, nucleolis pluribus composita ; 2, ielri- 

 spora cruciatim divisa, sparse^.. 



Kallymenia crihrosa ; stipes short, expanding into a very broad, simple 

 or bipartite, roundish reniform frond, cordate at base, and regularly 

 pierced with closely set circular holes, which are small toward the 

 margin, and larger towards the centre of the frond ; cystocarps 

 scattered over the surface.

dato-reniformem basi-cordataviforaminibus circularihiis crebris versus marfflnem

Descr. Root a flat disc, quarter inch in diameter. Stipes \-\ inch long, piano- 

 compressed, suddenly expanding into a lamina from a foot to two feet in 

 length and breadth, or twice as broad as its length, cordate at base, with a 

 roundish reniform outline, but scarcely two specimens of the same shape, 

 either quite entire or deeply cloven in the middle, or divided nearly to the 

 base into two roundish lobes ; the margin quite entire, but wavy, and more 

 or less plaited. Sometimes, from casual laceration and proliferous after- 

 growth, the outhne becomes more lobed. At all ages \\\e frond is pierced 

 with holes ; but they vary in dimensions according to the age, either of the 

 specimens, or portion of specimen. In the very young frond, and in the
