 liarly dark-green colour, paler heneath. 



79. N. (Lastrea) resinoso-fa'tiduiu, Hook. ; caudex ?, stipes 

 1^-2 feet loiii>- very stout angled when dry, glabrous (as is 

 the rachis) slightly scaly near the base, frond 3-4 feet long 

 coriaceous broad-oblong acuminate attenuated below in con- 

 sequence of the dwarfing of several of the distant inferior 

 pinna pinnate, pinnae numerous G-12 inches long 1 inch 

 wide from a broad sessile base which has a brown fleshy gland 

 l)eneath elongato-oblong or sublanceolate acuminated three- 

 quarters of tiie way down to the rachis pinnatifid, segments 

 linear-ol)long but gradually acuminate from the base, the 

 margins entire at length reflexed, veinlcts all simple slender 

 dark-coloured (hence conspicuous), sori copious submarginal, 

 involucres ivhen yoimgXziVs,^ membranaceous cordato-suborbi- 

 cular persistent, the disk dark-coloured vvhere the attachment 

 to the receptacle takes place. 



Ilab. Foot of Chimborazo, alt. 3000-4000 feet, n. 5300, in moist woods. Spruce, 

 n. 529'J, 5300, 5301, 5302 (" Filix odore resiiioso-fojtido ").— The presence of a 

 very conspicuous gland at the inner base of the pinuffi, and the narrow segments 

 of the latter, with some minor characters, such as the contraction of the lower 

 pinnae, are all I have to offer as the specific distinctions of this fine Fern. Mr. 

 Spruce observes, when recent, that it had a peculiarly " foetid resinous smell." 



80. N. (Lastrea) piloso-hispiduin, Hook.; caudex?, stipes?, 

 frond 4' feet long ovate-ol^long firm but not very thick coria- 

 ceous subvernicose hispid with short white spreading hairs 

 on both sides longer and more copious on the rachis costae 

 veins and veinlets, pinnate, pinnae very numerous crowded 

 less so towards the base from G inches to 1 foot long and 1-1^ 

 inch wide having a black transverse gland at the base be- 

 neath, from a truncate or rounded base (the two lowest pairs 

 of segments being often a little shorter than the rest) broad- 

 oblong acuminated deeply to within a short distance from 

 the costa jnnnatifid, segments approximate oblong or linear- 

 oblong straight scarcely subfalcate the margins entire and in 

 age slightly reflexed, veinlets numerous simple bearing the 

 small sori towards the apex consequently forming a marginal 

 series upon the segments, capsules few lax, involucres mi- 

 nute hispid very deciduous. 



Hal). Foot of Chimborazo, alt. 3000 feet, Spruce {u-ithuntmnnher). — Tropical 

 Western America seems to abound in very large frouded forms, witli broad jiinnae, 

 of a group which may be said to belong to the /^a/e«.v-section of our Nephrodhim ; 

 but of which, however different from A'', patens, it is very difficult to dctine thoir
