In the herbarium of tlie Missouri Botanical Oardt^n there is a slieet (proj.- 

 orJy labeled A. infcgcrnmum) without data, other than tliat it is of llie Reru- 

 liardi herbarium. 



The perfectly entire margins will distinguish this species at o\wi^ from all 

 exceptiu^i^ A, ncoffrunataise, to which it must be nearly allied. See under ,1.

Asplenium rectangulare Maxon, sp. nov.

 but the uppermost jK^tiolate (3 to 4 mm.) ; lower and middle pinna^ of nearly 

 equal size and form, 14 cm. long by 3 cm. broad, falcate, oblong-lanceolate, 

 broadest near the base but of nearly equal width in the basal third, then ta])er- 

 ing very gradually to a narrow acuminate ui>curved apex, at the base decidedly 

 unequal, the upper side exactly rectangular and rounded (not auriculate), the 

 lower cut away in a straight line to an angle of 35° from the midvein; margins 

 of the upper base crenate, of the middle and outer portions of the pimiiT^ irregu- 

 larly and inconspicuously shallow crenate-serrate; sori 10 or IT pairs to the 

 pinna, 16 to 20 mm. long, narrow, nearer tlie midrib than the margin, borne

«In this as in following papers the herbaria from which specimens are cited 

 will be indicated by letters; E, I). {\ Eaton Herbarium at Yale University; 

 G, Gray Herbarium; M, herbarium of the Missouri Botanical Gaixlen; X, her- 

 barium of the U. S. National Museum (U. S. National Herbarium) ; S, her- 



uarium or Capt. John Donnell Smith; Y, combined herbaria at the 



Botanical Garden. 



*In the Gray Herbarium there are two sheets of no 841, both being A, in- 

 iegerrlmum; and no. S41 in the Sauvalle llei'barium at Havana, Cuba, is the 

 same. The material which should be under this number at the D. C. Eaton 

 Herbarium is not to be found, nor is this number hi the herbarium of the New 

 York Botanical Garden. Christ (Engler's Bot. Jahrb. 24:105.1897) has listed 



a specimen of no. 841 as A. vomcriforme Hook, (Sp. Fil. 3: 109. pL 162, 1800). 



The plant thus referred may be either A. saUcifoliinfi or .1. rrcfnngularr. 



A. vomeriformc is apparently coufined to Peru and seems quite distinct from 

 either.
