POI.YPODIUM, '5' GONIOniLEBIUM. 29 



pt/cnosoriim of gardens! I have alluded to its relationship with P. menisciifo- 

 lium, but 1 believe tbey are truly distinct. 



274. P. (Gonioplilel)ium) GuatemaJense, Hook. ; caudex ?, 

 stipes a span to a foot long stramineous as well as the rachis, 

 fronds 2-3 feet long a foot or more broad firm-membrana- 

 ceous glabrous pinnated, pinnre rather distant 6-8 inches 

 long 1-1 :r wide sessile alternate elliptico-oblong more or less 

 acuminated entire or very ol)scurely serrated oljtusely rotun- 

 dato-cuneate at the base, uppermost ones more or less adnata 

 and even decurrent, ultimate jjinna petiolate or sometimes 

 coadunate at the l)ase with the one next below it, veins form- 

 ing a single fertile series of large costal areoles in which the 

 free soriferous veinlct arises from the point of junction of 

 the primary vein and the costa, more rarely an elongated 

 sterile arcole is formed between the fertile one and the costa 

 and parallel with it (as shown in the figure of Mr. Moore, 

 Ind. Fil. t. 58. f. 4), there are besides copious small areoles 

 without order between the soriferous ones and the margin 

 with or without an included free veinlet, but all sterile, sori 

 consequently in one series a little distance from the rachis. — 

 Phlebodium insequale, Moore, hid. Fil. I. c. Polyp. ina3quale, 

 Lowe, Brit, and Exot. Ferns, ii. /. 28 {not of Link). Gonio- 

 phlebium, J. Sni. 



llah. Guatemala, Skiiuier. — I am not aware that any description of this fine 

 and very distinct Fern exists. It ajjpoars to be scarcely known except in gardens. 

 I am so fortunate as to possess a native specimen from Guatemala, to which Mr. 

 Moore has attached his name of Phlebodium incpqnale, and of which his figure 

 (1. c.) of a fragment represents one form of the venation. 



2/5. P. (Goniophlebium) Chacapoyense, Hook.; caudex 

 creeping paleaceous with brown ovato-lanceoiate very glossy 

 scales, stipites approximate 4-7-8 inches long reddish-stra- 

 mineous glossy, fronds 6-10 inches long H-2 inches wide 

 firm subcoriaceo-mend^ranaceous (young fronds jnibescently 

 tomentose) dark-green above pale beneath oblong acumi- 

 nate pinnate, piniue numerous sessile erecto-patent 1 1-2^ 

 inches long \ of an inch wide (terminal one 3 inches long) 

 linear-oblong very obtuse entire, veins very conspicuous on 

 the pale under side very pellucid forming a single costal 

 series of soriferous areoles, the rest of the veinlets are mar- 

 ginal and free, sori (young) orbicular intermediate between 

 the costa and the margin. (Tab. CCLXXXl.) 



Ilal). Sesuja, Chacapoyas, Pern, Mathews, n. 3278. — This, as may be seen by 

 our fignrc, is very unlike any Fern with which we arc acquainted, especially any 

 Polypodium of the Goniophlebium section.
