Dr. Christ in some notes (L cO on this species (up to that time unpub- 

 lished) listed recently four of the writer's numbers from Jamaica and Guate- 

 mala, The lirst of these, from Jamaica^ Maxon 1558, represented iu the U. S* 

 National Herbarium 1)3' sheet no. 427820, may be rej2;arded as the type. 



The species was fully characterized by Jenman " under the name A><pJcn\um 

 ruiaccum Jlett. In his later studies Jenmau recognized the plant as distinct 

 from niiaccum but unfortunately assigned to it in the herbarium a specific 

 name already preoccupied hi this genus. Dr. Christ has indicated the main 

 distinctive characters. 



The following specimens are in the U. S. National Herbarium: 



Jamaica : Moist woods near tlie Mabess River, altitude 000 meters, Mn.rou 

 155S (tyt)e) ; rocky baidv in humid forest, vicinity of Morces Gap, alti- 

 tude 1,500 meters, lilaxon 2701; between Morces Gap and Vinegar Hill, 

 Undencood 1377* 



Guatemala: Tree trunivs in humid forest, on the trail between Sepa<'uite 

 and Secanquim, Alta Verai)az, altitude 1,000 meters, Mawon d Bay 

 3257; on a stump iu humid forest, on the trail from Senahu to Actala, 

 Alta ^^rapaz, Maxon tG Ilaij 3310.

The type of Dliaazhtm franconii^ is from Oaxaca, Mexico. As illustrative 

 may be cited the following (Jnatemalan specimens in the National Herbarium: 

 John Donnell Smifh\^ no. (i3(!, collected at San Pedro Carcha, Depart. Alta 

 Veraimz, altitude 1,150 met(H-s, by vou Tiircl<heim, June, 1SS5; and Maxon d 

 Hay no. 3324, collected in Alta Yerapaz, along the trail l>etween Senahu and 

 Actala, January 17, 1005. These agree closely with the original collection of 

 Liebmann as represented by a fragment iu the herbarium of the New York 

 Botanical Garden. 



Compared with these the Jamaican plant is readily seen to be distinct. The 

 fronds are broadly triangular ovate, tripinnate or even qnadripinuatilid, the 

 pinnie ordinarily 2U to 25 cm. long ^ and 10 to 13 cm. broad, the pinnules to 7 

 cm. long, lanceolate, stipitatc (0.5 cm. m the largest), acuminate. The larger 

 pinnules comprise about S pairs of oblong or ovate-oblong obtuse segments, of 

 which the lowermost are free, deei>ly lobed and almost comparable to the pin- 

 nules of the much simpler D. franconis. The contrast with D, franconi.'^ in 

 size, form, and degree of subdivision is too pronounced to require more detailed 

 comparison. 



D. oreophUtnn is not infrequent in humid depressions nearly up to 000 meters 

 in the Blue mountains of Jamaica and is oftenest met with in a sterile condition. 

 Ordinarily it is found fertile only in the vicinity of forest openings, and in such 

 cases there is to be noted a marked dimor])hic tendency, the sori (if present at 

 all) being borne very closely and in great profusion, with a corresponding 

 reduction of leaf tissue. It is apparently confined to Jamaica. Jenman's speci- 

 mens (the types) are at the New York Botanical Garden. The following are 

 in the National Herbarium: Maxon 1178, 2483, 237G; Clnte 270; Moore; and 

 one from the Botaincal Department of Jamaica.
