under that name another sp.* quite unlike it or 
my Acr. maritimum ! — 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, NESQRIS 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. Qlsynium ; read Sisyrinchium throughout, 
misprinted Siryrinchium in the synonyms. 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
