Near N. floccigera but in aspect very distinct from it; longest fertile 

 pinnae often sterile at the finely acuminate, serrate-crenate apex.

From the presumable synonyms of this species (mentioned by me in Sup- 

 plem. I, Corn, 48) may be concluded that I thought it possible that N. 

 pilosula may be identical with N. rufescens Pr. (N. hirsutula Pr., C. Chr., 

 Ind. Fil., p. p.) and N. pilosa Pr. 



H.I.H. Prince Roland Bonaparte was so kind to forward to me a copy 

 of the diagnosis and of the plate of N. rufecens given by Wawra in Bot. 

 Ergebn. etc., 200, tab. CI. 



If the diagnosis and plate quoted are quite correct N. pilosula is cer- 

 tainly not indentical with N. rufescens and the latter not with N. hirsutula, 

 though the 3 species are most closely allied. N. rufescens is drawn with 

 the spores quite smooth while those of N. pilosula are rough with crowded, 

 slightly elevated, verruciform projections. 



It is possible that N. pilosula is indentical with N. pilosa. This may 

 be settled by a botanist who has at his disposal a correct description of 

 the species. 



Ophioglossutn Raciborskii, v. A. V.R.; O. pedunculosum, Desv., var. 

 lanceolatum, v.A.v.R., Mai. Ferns, 775 — 776; 0. moluccanum, Sehl., forma 

 lanceolata, Rae, in Nat. Tijdschr. N. I., LIX, 237, tab. II, fig. 4. 



Rhizome short, + erect, cylindrical. Whole plant 10—18 cm. high. 

 Barren segment placed at, above or below the middle, lanceolate or 

 oblanceolate, + 3 —472 cm. long, + 1 — l'/2 cm. broad, blunt or acute, 

 whether or not minutely mucronulate-apiculate, the base narrowed into a 

 shortly linear-cuneate haft; marginal cells longitudinally linear, with the 

 outer wall straight. Texture thin when dry; costa fine, somewhat stouter 

 towards the base. Fertile spike on a peduncle 3—9 cm. long. — The 

 description is taken from C. A. Backer's No. 23403, from Klappa Noenggal, 

 near Biiitenzorg, which differs from Raciborski's drawing only in having 

 the areolae near the margin longitudinally elongated, not roundish. — 

 0. pedunculosum Desv. differs in having the marginal cells short and 

 broad, with the outer wall convex.
