Hab. Fiji Islands, Brackenridge, Milne. — "This differs from A. aimilnm in the 

 obtuse fronds and in the presence of numerous small peltate scales on both sur- 

 faces." Such lepidote fronds are not uncommon in A. conforme. I possess no 

 authentic specimen of this Acrostichum, but I think I have the true plant from 

 Milne; if so, its chief distinguishing feature from A. conforme is the narrowly 

 attenuated base of the frond ; but even this is variable.

Hab. Sandwich Islands, Kaulfuss, attaining an alt. of 8000 feet, Brackenridge, 

 Hillebrand, n. 55 mid 57 .' — Of this I possess no named specimen save from Dr. 

 Hillebrand. I can well conceive, however, that it is the true plant, and I fear can 

 hardly be distinguished from A. conforme. In my specimen (n. 55) the caudex 

 is short, thick, creeping, paleaceous with rather large scales ; sterile frond 5 inches 

 long, ^ an inch wide, linear-oblong, obtuse, attenuated at the base, coriaceous on 

 a stipes 2 inches long, black, and jointed near the base ; fertile fronds 3-5 inches 

 long, on longer stipites. Dr. Hillebrand's n. 57 has the fronds all uniform, more 

 attenuated, with stipites not an inch long, and one of the fronds partially 

 sterile, the extremity soriferous. 



11. A. (Elaphoglossum) scalpeU urn, Mzxt. ; "sterile fronds 

 coriaceous glaucous ovate narrowly decurrent at the base 

 edged by a thickened discoloured margin, stipes and costa 

 sparsely scaly, veins slender excurved ; fertile fronds linear 

 longer stipitate repand, caudex thick scaly, scales lanceolate- 

 linear long attenuated crisped at the apex." Fee. — A. scal-

Hab. Brazil: Rio Negro, 7l/«rfM« ; Go\s.z, Gardner, n.AO'il. — Very much like 

 A. ladfolium. Fee's figure is quite correct, and evidently taken from Gardner's 

 specimens ; indeed, Gardner's locality is the only one expressly recorded by him 

 and Moore. The thickened margin of the frond is dwelt upon by Fee, but on 

 which Martins himself says nothing. My specimens show this thickened mar- 

 gin more decidedly on some fronds than others. I fear it must be considered 

 a very dubious species, and the A. consobrinum, Kze., no less so.
