broader than long, and subhorizontal ; on the ascending ones the j are more 

 or less attenuated and 1 — 2 costate at the base, and erect or nearly so. In 

 length the style is IJ times, and the elaters 3 — 5 times, the diameter of aspoie. 

 Spores with more numerous and larger muriculje than in Fossombronia pusilla. 

 Separated from Fossombronia chiefly by its dioicious inflorescence, and by the 

 perianth being (apparently at least) an expansion of the apex of the stem. 



Plagiochasma ertthrosperma, Sulliv. in Herb. 



P. fronde expanso-obovata (3 — 5 lin. lat.) pallido-viridi rugulosa late 

 fuscescente marginata, subtus dense radiculosa squamosaque ; squamis albidis 

 setaceo-incisis versus apicem ultra marginem exstantibus ; pedunculo 5 — 8 

 lineas alto basi nudo apice paleaceo ; sporis aurantiaceo-rubris tuberculatis ; 

 elateribus 4-spiris. 



Rocky Mountains, E. Hall. 



Remarkable for the red spores, and for the white, fringe-like scales extending 

 beyond the margin of the frond towards the apex. 



Sauteria limbata. 

 ? Grimaldia limbata, Austin, MSS., 1865. 



S. fronde obovato-oblonga subdichotoma concava reticulato-papulosa laete 

 viridi latissime marginata, subtus nigro-purpurea valde incrassata, margine 

 nigro-purpurea membranacea subplicata undulato-crenata involuto-incurva • 

 squamis arete imbricatis sanguineo-purpureis, inferioribus amplis obliquis 

 bicornibus nodoso-dentatis juxta marginem positis, superioribus majoribus 

 lanceolatis attenuatis frondis marginem superantibus incurvis; pedunculo 

 subunciali pallido nudo ; receptaculo femineo 1 — 3-carpo, subtus multum sed 

 breviter paleaceo. 



Under wet rocks. California, Bolander. (No. 4619.) 



Remarkable for the broad, wavy, dark purple, membranaceous margin of 

 the frond. The scales towards the apex of the frond increase in size and be- 

 come abruptly two-horned ; these horns (laciuite) are very long and narrow 

 and extend beyond the margin of the frond as a strongly inflexed fringe ; the 

 very apical ones are triangular-subulate or setaceous, bifid or entire, and 

 extend still farther beyond the margin of the frond, and in the fertile plant 

 they become (by age) whitish. Pedicel sulcate, naked at the base. Receptacle 

 very obtuse (l-iruited in our meagre specimen). 



? Sauteria crassipes, Aust. 



? S. fronde obcordata subcuneatave bifida fuscescente-purpurea vel viridi 

 supra subpapuloso-reticulata minutissime porosa, squamis ventralibus purpu- 

 reis apicem superantibus ; pedunculo breviusculo (6 — 8 lin. alto) parcissime 

 paleaceo, circa basin nudo vel parce barbato-involucrato, versus apicem in- 

 crassato ; receptaculo femineo 4 — 7 inciso-lobato, subtusque eodem numero 

 carpo brevissime submultumque paleaceo ; capsula firmiuscula distincte pedi- 

 cellata ; elateribus tri( — quadri?) spiris ; magis inimatura. 



Japan, on hillsides. Com. Rodgers, N. Pac. Expl. Exped. 



I have doubtfully referred this species to Sauteria. It resembles Preissia 

 y^Tj much, — also, in some respects, Duvalia. It is remarkable for the pedicel 

 being much thickened towards the apex. There are occasionally a i'^vf scale- 

 like palea on the peduncle, and a few filamentose scales or hairs on the frond 

 about its base. Involucre rather large, somewhat flattish, fuscous-green tinned 

 with purple, and it bears as many capsules, underneath around the margin, as 

 there are lobes. On account of the immature state of the specimens, it is not 

 possible to tell in what manner the capsule ruptures.
