 The following specimens are in the r. s. National Herbarium:

 The type <d* Diplazium franconis is from Oaxaca, Mexico. As Illustrative 

 may he cited the following Guatemalan specimens in the National Herbarium: 

 John Donnell smith's ii... 636, collected at San Pedro CarchA, Depart Alta 

 Verapaz, altitude l. ir.<» meters, by von Tiirckheim, June. issr, : and Maxon & 

 Hay no. :;:;l! j. collected in Alta Verapaz, along the trail between Senahti ami 

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

 Liehmann as re]. resented hy a fragment in the herharium of the New York 

 Botanical < Jarden. 



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

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

 pinna? ordinarily 20 to 25 em. long h and l<» to 13 .in. broad, the pinnules <"> to 7 

 cm. long, lanceolate, stipitate (0.5 em. in the largest), acuminate. The larger 

 pinnules comprise aboul s pairs of oblong or ovate-oblong obtuse segments, of 

 which the lowermost are free, deeply lobed and almost comparable to the pin- 

 nules of the much simpler h. franconis. The contrast with h. franconis in 

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

 comparison. 



/>. oreophilum is not Infrequenl in humid depressions nearly up to 900 meters 



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



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



there is to be noted a marked dimorphic tendency, the s..ri (if p resent at 



all) being home very closely and iii great profusion, with a corresponding 



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