prsesertim G. leptophyllse analoga, diversa frondibus fer- 

 tilibus distinctis et prsesentia involucri dorsum totum 

 pinnulge tegentis : His notis autem Cryptogramma convenit 

 cum Pteridi thalictroidi Swartz (a nobis tredecem- adhinc 

 annis in Prodr. Fl. Nov. Holl. i. p. 154, uti genus dis- 

 tinctissimum indicata). lii hoc genere, (Teleozoma nob) 

 Capsulse sessiles, annulo corapleto latissimo, distinctse in 

 serie simplici insident venis costse parallelis, utrinque vel 

 solitariis marginalibus, vel binis altera superficiaria. Teleo- 

 zoma insuper insigne est sporis in ordine naturali forsan, 

 in tribu quantum scio maximis obtuse trigonis pulchre 

 striatis, puncto unico opaciore. 



CRYPTOGRAMMA ACROSTICHOIDES. 



Cryptogramma, frondibus bipinnatifidis, sterilium pin- 

 nulis ovalibus crenatis ; fertilium demum explanatis, soris 

 linearibus discum totum occupantibus. 



Hab. In shady rocky woods, between lat. 56° and 60° 

 north. (First found by Mr. Menzies at Nootka Sound.) 



Desc. Filioo 4-8-uncialis, glabra, Isete virens, frondibus 

 csespitosis, stipitatis, crasso-membranaceis opacis venis vix 

 ad versus lucem conspicuis. 



Frondes exteriores csespitis steriles, circumscriptione 

 lanceolatse bipinnatifid^ apice pinnatse pinnis distinctis 

 alternis, brevissime petiolatis ; pinnulis confluentibus, ovali- 

 bus obtusis, crenatis, inferioribus passim dentatis, omnium 

 venis e costa vix prominula acutangulis distinctis simpli- 

 cibus bifidisve intra marginem crenaturse desinentibus. 

 Stipites pallidi, subtus semiteretes antice bisulci, infra 

 medium conspersi squamulis lineari-lanceolatis acumi- 

 natis disco fusco-atro limbo pallido, supra glabri. Bachis 

 epaleata, angusta, compressa, colore et fere substantia 

 frondis, Frondes centrales fertiles stipite sterilium longiore 

 alioqui simili insidentes bipinnatse : pinnae petiolatae ; pin- 

 nulae omnes fructiferse distinctse inferiores brevissime 

 petiolatae ; ante explicationem involucri lineares, limbo
