under that name another sp. quite unlike it or 

 my Acr. maritimum I I call it Acr. acumi- 

 natum Raf. pinnulis lanceolate acuminate base 

 rounded petiolate entire thin costate, smooth 

 above like stipes, beneath quite fructiferous all 

 over. In Venezuela, ten feet high I have 

 found in Collins Herb, a very curious fern of 

 Florida collected by Kin or Baldwin again as 

 a doubtful Acr. aureum ? which forms a most 

 beautiful and wonderful N. G. of dorsiferous 

 ferns without Sori, but with capsules uncon- 

 nected punctiform scattered like minute dots. 

 It shall be fully described and figured -in my 

 PTERiKON,a work now preparing. I announce it 

 meantime as a great discovery proving that the 

 capsules of Ferns may be solitary, and I call it. 



5, NESORIS BICOLOR Raf. smooth, bipin- 

 nate, yellow beneath, pinnules sessile oblong 

 crenate lobate, base acute, end obtuse, above 

 nervose flabelate, behind enerve golden fur- 

 furascent, capsules irregularly scattered. Pe- 

 dal, stipes brown shining convex behind, groov- 

 ed before, pinnules alternate, 25 to 33 on each 

 branch, gradualy smaller and nearly confluent. 

 In Florida I have several other N. G. of 

 Ferns, but none so beautiful and anomalous ; 

 probably type of a new family NESORIDES. 



6. OLSYNIUM ; read Sisyrinchium throughout, 

 misprinted Siryrinchium in the synonynii. See 

 878 flora tellur. where it is again described, 

 another sp. added, and the akin blended Genera 

 compared and settled. 



Monograph of KUHNIA. 



Although I thought this monograph nearly 



complete, I have found other new sp. in Collins 



Herb, and I am told that Decandole in his 5th 



volume just published has many sp. under 3
