their own terminal cells. From axils of laciniae, the apices of 

 young ramu】i， either sterile or fertile, make their appearence. - 



Cystocarps and tetrasporic receptacles are axillary and pedi- 

 cellate. Their total lengths (includinp* pedicels) are usually same 

 as those of lacinise. Receptacles of tetrasporangia are oval, 

 containing numerous cavities excavated under the surface-coatinp-. 

 The wall of this cavity is composed of loose, nioniliform nlaments, 

 among which elongated, clavate or oDionp- tetrasporangia, divided 

 in zonate iranner, are situated. 



Procarps are unknown to me. Cystocarps are formed 

 solitary or often two together, inserted obliquely beneath the 

 apices of fertile ramuli, and are sometimes accompanied by abor- 

 tive lacinise. The form of cystocarps is irregularly roundish and 

 more or less reniform being slightly appressed in the same plane 

 with the surface of frond. Each is furnished with a more or less 

 gaping slit-like opening- which runs on the summit in the direction 

 of the longer axis. Placenta Is laterally appressed on the plane 

 parallel to the flattish side of cyslocarp and neucleus is laterally 

 flattened by the closely lymo- flaps of thick pericarp. Placenta is 

 composed of numerous and several times forked spore-filaments 

 〜\hich are densely packed together. 丄 he terminal cells of these 

 tufted spore-filaments which form the \ aulled surface of placenta are 

 transformed into globular or elongated spores. Neucleus is mostly 

 single, but another smaller isolated one is formed in the same 

 cystocarp. In some specimens, fertile ramuli become abortive and 

 develope into irregularly branched ramuli. They are mostly 

 destitute of laciruae, but sometimes a few of them are formed on 

 those ranuili and even cystocarps are thus developed. 



Colour, when alive, is deep red, changing, after long* immer- 

 sion in water or exposure to air, to beautiful red and then orange. 

 Substance is thin and membranaceous except thickened midrib
