208 ACROSTICHUM, § EL APIIOG LOSS UM. 



.1-1^ wide below the middle coriaceo-membranaceous from a 

 truncated or very obtuse base ovato-oblong gradually and 

 sharply acuminated scarcely thickened at the margin, costa 

 slender, veins very slightly prominent beneath; fertile honds 

 much smaller scarcely 1 ^ inch long oblongo-acuminate with 

 under side wholly soriferous. — Hook. Ic. PL t. 856. 



Hab. Ecuador, sides of ravines, Tambillo. near Quito, Jameson. — Somewhat 

 allied to Desvaux's A. petiolosmn, but very distinct. 



29. A. (Elaphoglossum) minutum, Pohl ; " small, fronds 

 entire decurrent; sterile ones lanceolate helveolous acute at 

 both ends membranaceous, stipes and costa scaly ; fertile 

 ones half-shorter rather obtuse at the apex, caudex repent 

 clothed with ovate acute fulvous scales." Fee. — Pohl, in Fee, 

 Acrost.p. 39. /. 10./. 3. 



Hab. " Brazil, Pohl." — Fee has seen only one specimen of this little plant, 

 ■which well represents an Acrostichwn I have from Venezuela, n. 9G8 of Fendler ; 

 but it does not accord with Fee's characters of the colour of the frond or its 

 membranaceous texture. This latter plant is referred by Moore to A. affine {A. 

 unitum, Fee). 



30. A. (Elaphoglossum) acr'ocarpon, Mart. ; caudex 1-2 

 feet long thick as a swan's quill recumbent terete, at the 

 apex only ascending clothed with subulato-setaceous dark- 

 brown spreading scales, stipites alternate upon the caudex 

 numerous terete subulato-setaceo-squamose 2-3 inches long 

 of the sterile frond ; sterile fronds firm-coriaceous 3-4 inches 

 long 4-5 lines wide linear-oblong obtuse dark-green slightly 

 attenuated below, the margin recurved, above dotted with 

 minute whitish fringed ovate scales beneath naked except 

 the prominent costa which has hair-like scales ; fertile fronds 

 on very long stipites and rising much above the sterile ones 

 with which they accord in shape and size but they are plane 

 not recurved at the margin and beneath wdioUy soriferous, 

 veins evident on the under side patent. — Mart. Crypt. Bras, 

 p. 85. t. 23. Fee, Acrost.p. 39. Olfersia, Pr. Elaphoglos- 

 sum, Moore. 



Hab. Brazil, Minas Geraes, Martins. New Granada, Purdie. Ecuador, on 

 Mount Mulmul, alt. 8000-9000 feet. Spruce, n. 5229.— It is a pleasure to come 

 to such a fine and distinctly marked species as the present, after wading through 

 such a host of dubious ones. 



31. A. (Elaphoglossum) diinorphum, Hook, and Grev. ; 

 caudex horizontal or subascending creeping scaly at the apex
