GELIDIUM GLANDUL.EFOLIUM, 



Hook. fil. et Harv. 



Gen. Char. Frond firmly cartilaginous, linear, compressed, decompound- 

 pinnate, composed of three strata ; the medullar 1/ stratum of densely 

 packed, interwoven, longitudinal filaments ; the intermediate of poly- 

 gonal cells ; the cortical of minute, coloured cellules arranged in hori- 

 zontal, moniliform series. Fruct. : 1, bilocular conceptacles immersed 

 in the ramuli, containing, within a thick pericarp, pedicellate, pear- 

 shaped spores, dispersed over both surfaces of a medial dissepiment, 

 which is united to the pericarp by slender filaments; 2, cruciate 

 tetraspores, forming sori in dilated ramuli. — Gelidium [Lam.), from 

 gelu, frost, whence also gelatine; but none of the species are ge- 

 latinous. 



Frons comeo-cartilaginea, linearis, anceps, pinnathn decomposita, tribus stratis 

 cellularum contexta ; medullari ex filis tenuibus intertextis longitudinalibus, 

 intermedio ex cellulis polygonis, corticali ex cellidis minutis coloratis in Jila 

 horizontalia brevissima seriatis composito. Fruct. : 1, cgstocarpia bilocidaria 

 in ramulis innnersa, ad dissepimentum longitudinale fills tenuibus cum peri- 

 carpio crasso junctum, sporas subpyriformes sparsas pedicellatas foventia. 



Gelidium glandulcefolium ; root branching ; frond very narrow, two-edged, 

 tall, distantly bi-tripinnate ; pinnae few, opposite, naked at base, op- 

 positely or fasciculately pinnulate above; pinnules very long, filiform, 

 simple or forked ; fructiferous ramuli minute, setiform or glandular, 

 in some specimens containing conceptacles, in others tetraspores. 



G. glandulsefolium ; radice ramosa ; fronde angustissima ancipili elata plus 

 minus bi-tripinnata ; pinnis paucis oppositis basi longe nudis supra opposite 

 v.fascicidatim pinnulatis ; pinnulis longissimis filiformibus simplicibus furca- 

 tisve ; ramulis fertilibus minutis setiformibus, nunc cgstocarpia, nunc telra- 

 sporasfoventiis.
