 J. Smith and Presl refer to their Lastrea propinqua, nos. 255, 252, 151, and 80; 

 I confine my references to the two latter. No. 252 is a Microlepia, and n. 255 is 

 undoubtedly N. membranfolia, Presl, who himself remarks, " affinis quodammodo 

 L. membrancEfolia," which can only be said of 255. The specimen of Aspid. in- 

 termedium, Blume, in my herbarium, Mr. Moore ascertained to be identical with 

 this, and Blume observes, " F.-mas, Sw., diversum laciniis serrulatis pinnisque 

 inferioribiis baud bipinnatifidis." Our specimens from Bonin are much larger 

 and more compound, and Mr. C. Wright's {Lastrea propinqua, J. Sm.), as well 

 as our n. 151 of Mr. Cuming, have the base of the long stout stipes clothed with very 

 long erect setaceous bristles, f of an inch long. It is clearly a variable Fern, 

 which requires a good suite of specimens in order to define the species accurately. 

 Great injury is done to this department of botany, above all others, by hastily de- 

 scribing from imperfect individuals. 



127. N. (Lastrea) recedens, Hook.; caudex (of a very 

 young specimen) a short thick ascending rhizome paleaceous 

 with subulate ferruginous scales, stipites tufted a span to a 

 foot long rather slender very scaly at the base the rest and the 

 rachises rather densely fusco-pubescent, fronds a foot long 

 and equally broad at the base firm-membranaceous deltoid 

 more or less pubescent on both sides subglandulose beneath, 

 bi- below tripinnate, primary pinnee broad-oblong acuminate 

 petiolate patent (but not horizontal) from 3-6-8 inches long 

 the basal ones much the largest 2i inches broad, secondary 

 ones oblong sessile and decurrent at the base so as to form a
