 System. XI, p. 102. Eupogonium capillare Kuetz. Sp. p. 799. — 

 Fronde teretiuscula, perflaccida, vage pinnatiui ramosa, fere tota 

 articulata, caule ramisque inferne denudatis glaberrimis tenue cor- 

 ticatis, apice mollissime penicillatis, penicillorum filis quoquover- 

 sum exeuntibus a basi monsiphoniis tenerrimis acute dichotomis, 

 demum stichidiiferis ; stichidiis lancoideis, longe acuminatis; cysto- 

 carpiis in medio ramo oblique sessilibus, ovato-urceolatis ; articulis 

 ramorum polysiphoniis diametro 4-plo longioribus. 



Hab. in oceano Australi ad oras Tasmaniae, prima vice ad «Geor- 

 getown » lecta (Harvey). — Caespes diffusus, 15-20 cm. longus, 

 fronde inferne crassitiem sequans pennse passerinoe, sursum sensim 

 in crassitiem capillarem attenuata, pinnatim decomposito-ramosa, 

 caule ramisque majorihus obsoletius articulatis, minoribus mox 

 articulatis licet tenue corticatis, superioribus omnibus subnudis 

 distincte articulatis, articulis diametro circiter quadruplo longio- 

 ribus. Rami inferne ramulis denudati aut sparsissime ramulo pa- 

 tenti obsiti, superne ramique ultimi ordinis aut subpamultimi apice 

 mollissime ramuloso-penicillati. Ramuli penicillorum byssoidei, ad 

 geniculum quodque quoquoversum exeuntes, nunc distantiores, a 

 basi monosiphonii et tenerrimi, levissimo aqua?. motu fiuctuantes, 

 densissime dichotomi axillis acutis, sensim attenuati, obtusiusculi, 

 articulis 4-plo et ultra diametro longioribus. Stichidia in ramulis 

 nata, pedicello articulato suffulta, lancoidea longeque acuminata, 

 juniora diametro 5-6-plo longiora, effceta adhuc magis elongata, 

 (e facie) subtriplicem seriem tetrasporangiorum monstrantia; sunt 

 revera Dasyce, ut docet icon Harveyana. Cystocarpia in ramo minuto 

 ad mediam fere partem oblique sessilia, apice rami supra cystocar- 

 pium continuatum ramoso et penicillato, ovata basi non truncata sed 

 paulisper inferne attenuata, carpostomio producto urceolata, peri- 

 carpio longitudinaliter celluloso striato, nucleo hemisphserico ele- 

 vato. Sectione rami conspiciuntur siphones pericentrales 5, totidem 

 alternantibus corticalibus cincti. Color coccineus. Specimina exsic- 

 catione chartae arctissime adhaerent.
