 p. 45, Callithamnion inordinatum Zanard. Callith. p. 12, J. Ag. 

 Sp. II, p. 20, Epicr. p. 11. — Filis capillo tenuioribus intricatis 

 hic illic arcuato-recurvatis irregulariter ramosis, ramis ramulis- 

 que patentissimis; articulis longitudine varia s;epe diametro 4-8- 

 plo longioribus; tetrasporangiis singulis breviter pedunculatis ra- 

 mulis plerumque oppositis. 



Hab. in mari Adriatico ad oras Dalmatke (Sandri) — Caespes 

 vix 2-3 cm. altus. Fila tenuissima, decumbentia et robustiora usque 

 ad 30 ij.. crassa, erecta 12-24 \i. crassa, dense intricata, rigidiu- 

 scula, varie flexa et arcuato-recurvata irregulariter ramosa. Rami 

 ramulique nunc alterni, stepissime secundi, quandoque oppositi, 

 crebri vel iongo intervallo distantes, plerumque angulo recto egre- 

 dientes, longiores brevioribus intermixti. Articuli longitudine in 

 ipsis ramulis insigniter varia brevissimi longioribus intercalati. 

 Sec. Hauck vix hyec species differt a Spermothamnio roseolo (Ag.) 

 Pringsh.; propter cystocarpia ignota de genuina affinitate vix ju- 

 dicare licet.

 filis primariis repentibus radicantibus, secundariis erectis secunda- 

 tim decompositis, pinnulis elongatis, erecto-patentibus, simplicibus 

 vel pectinatis, fastigiato-flabellatis ; articulis cylindraceis, diametro 

 3-6-plo longioribus ad genicula haud contractis; tetrasporangiis 

 ad basin pinnularum solitariis pedicellatis vel in ramulis propriis 

 seriatim aggregatimve dispositis sessilibus. 



Hab. ad frondes Codii tomentosi in mari Ligustico ad

 longi, filis rhizomatoideis 50-60 [j.. crassis, radicibus apice discoi- 

 deo-expansis matrici affixis, filis erectis pluribus pinnatis, pinnis 

 pinnulisque plerumque unilateralibus ita ut ambitus pinme obverse 

 triangularis evadat. Color plantulae recentis amcene ruber, siccse in 

 brunneum tendens. Substantia membranacea. Caute dignoscatur a 

 Spermothamnio stricto (J. Ag.) Ardiss., quocum conjunxit Hauck.
