98 NEPHUODIUM, § LASTREA. 



may be the differences in words between the two plants, I cannot see the shadow 

 of a difference between this and N. macrourum. 



65. N. (Lastrea) Serra, Desv. ; caudex creeping and, in 

 one of my specimens from Mr. Spruce, branched and sub- 

 scandent thick as a man's finger very scaly, stipes 1^-2 feet 

 long very stout curved at the base very smooth, fronds 2-4 

 feet long ovate acuminate broad at the base pale green co- 

 riaceo-chartaceous glabrous or subpubescent on the costse 

 beneath pinnated, pinna3 numerous 6-12-14 inches long \ 

 an inch to nearly 1 inch wide subfalcate or flexuose from a 

 sessile subtruncated base linear-oblong elongate acuminate 

 pinnatifid about halfway down with -copious very approximate 

 narrow-ovate very acute falcate subserrated segments, vein- 

 lets simple lowest pair approximating below the sinus but 

 not uniting, sori copious near the margin and the costule 

 prominent, involucres orbicular reniform persistent subhir- 

 sute.— Aspid., Sw. Syn. FiL Schk. Fil. p. 35. t. 33 b ? Willd.

 New Granada, Holton, n. 75. Boqueta, Veraguas, Seemann, n. 15.52. Ecuador, 

 Bafios, Spruce, n. 5296 (caudex apparently soandent, very thick and scaly), and 

 Chiraborazo, elev. 4000 feet. Spruce, n. 5296. Cuba, Wright, n. 1003, 1004.— 

 This species is perhaps best recognized by its rigid texture and usually brighter 

 green colour, than by any technical characters, many of which are common to all 

 the /;rt!/e«s-group, and I am in some cases at a loss to decide whether some of my 

 specimens belong to this or to Kaulfussii or macrourum. One thing is quite cer- 

 tain, that none of the recognized samples at all accord with the ^gnve, ol Aspidlum 

 Serra in Schkuhr. 



6Q. N. (Lastrea) Raddianwn, Hook. ; stipes a span to a 

 foot long stout and as well as the stout straight j-achis 

 clothed with ferruginous lanceolate scales very woolly at their 

 base, fronds subcoriaceous 1-2 feet long blackish-green when 

 dry, ovato-oblong acuminate pinnatifid at the apex, pinnae 

 numerous sessile 3-4 inches long 1 inch wide oblong shortly 

 and bluntly acuminate deeply almost to the rachis pinnatifid, 

 the segments oblong-falcate very obtuse entire, lowest pairs 

 of pinnse deflexed, costa and costules clothed with lanceolate 

 paleaceous scales and buUate cellular ones, veinlets simple 

 each bearing a sorus so near the costule as to be partially 

 covered with the scales, involucre small reniform. (Tab.
