Nereiain nustrak'iii xx'Vi'i-a vidi \\vo a'IatL' aut evoluLionis stadio sub formis 

 adnioduni divcrsis obvcniix'. Planlani, (|uain niagis juveiiilem l'acilius agnoscerein, 

 tilis suis cont'ervoidi'is, ranios iatiiul()S(]ue superiores. conia laxa et niollissiina in- 

 vestientibiis, Desniarestiani aeuleatani potissiinuni referre, jani supra monui. Sul) 

 stadio, (pioil |iotius senile judicareni, otî'ert plantain coma demidatam, apicil)us 1ère 

 in acunieii i)ruductis. At inter utruni(|ue stadîuni quasi interniedias plantas vidi 

 fructiferas, suo ukkIo typuin Sporochnoidearuni, me judicc. sat conspicue indicantes. 

 Sub hoc sladio plantam in T'Y. Tasmai/lca depictain ïuisse lul)enter dixissem. 



8iib stadio, (|uo(l maxime juvénile vi<li. planta Jilis suis eont'ervoideis obsita. 

 ut jam dixi magis Desniarestiani aeuleatam, (piain aliam quandani niihi cognitam 

 ret'ert. Ipsi raini ratnuli(jue in cus[)idem molliorem sunt excurrentes; inl'ra hune, 

 apicem lilorum quasi peiiicilli longius deorsuin pluma mollissima obtegunt; ipso 

 api(;e acuminato et iiicrescente tenninato (|uasi penieillo paulo densiore. Hune vero 

 penieillum terminalem (l'orsan magis deeiduum) nunc delicere vidi. Inl'ni hune api- 

 cem rami vidi i-aeliides, alterne quasi contractas et expansas, quasi nodosas; ipsis 

 nodis loca l'erlilia indicantibus ; penicillis nimirum lilormn ex nodo egredientibus, 

 soro supra su[)erliciem i])sius racliidis elevato conslitutis. Organa sori pyril'ormia 

 vidi, invicem distincta. ai ad[)roximala, adixa pedic'cUo teiiuiore ; (piasi articulos 

 3- 4 super[)ositos, polysiplioneo modo in [)artes })aucas (hvisas monstraiitia. in bis 

 corpusculis pyriformibus s|)0tangia plurilocularia Generis agnoscenda putarem. 



Specimina alia vidi coma uberiore et densiore sfepe iiistructa, alio modo t'rucli- 

 fera; soros nimirum in liis supi'a ramos (•onspicue aduUiores pi-ovtaiientes puto, 

 verrucas latérales constituentes, cystocari)ia Gracilaria; cujusdam aîinulantes. Hpec 

 sunt organa, quse in icône Harveyana depicta videas; glol)oso-co!nca iljidem depin- 

 guntur; qualia depicta, eadem diceres sistere t'ructus notissimos Sporoehiii. at sul) 

 forma diversa et Genus forsan pro])rium intlicantia Ilos l'ructus in |>luribus spe- 

 ciminibus adultioribus ol)servavi, at coma stepe destitutos et magis irregulariter 

 hemisphtericos, potius verrucas aîmulantes. Ilis dissectis vidi eadem constare tum 

 paranematibus pauci-articvdatis, articulo terniinali obovato instruclis. tum organis 

 paulo mai(»rilnis intermixtis, (pue sporangia unilocularia obovata sistere putarem. 

 Fnuftus lios, cystocarpia a'nuilantes, nullo pericarpio ciiiclos esse, dixissc placet. 



Denirpie aildere ]>lacet me (picxpie s[)ecimina vidisse, (pia' dcimdata ejusdem 

 planta' lubeiiter dicerem; adparatus penicillorum in bis aut omuino ddici'ix'. aut 

 nubecula vix «•onspicua. adest lamulos suf)remos cingens. in bis rami ra,muli(|ue
