bearing 8-13 pairs of obscure simple oblique veins which approach 

 the margin ; sori 6-12 pairs to the pinna, borne at half the dis- 

 tance to the margin. 



Type in the herbarium of the New York Botanical Garden ; col- 

 lected on Blue Mountain Peak, Jamaica, at an altitude of 1950-2225 

 meters by L. M. Underwood, no. 1449, February 11-12, 1903. 

 There is a fragment of the type specimen in the U.S. National 

 Herbarium, no. 428420. Other specimens to be referred to this 

 species are : Underwood no. 1469 and Underwood no. 249O, both 

 from the summit of Blue Mountain Peak, and Maxon no. 1346a from 

 the highest slopes of John Crow Peak, altitude 1650-1800 meters. 

 There is additionally a single sheet in the Jenman herbarium. 



Jamaican specimens of this species were referred by Jenman* to 

 Polypodiiimfi) mum Klotzsch,"'' founded upon material from Chile and 

 Guiana. They accord only indifferently with Klotzsch's descrip- 

 tion ; and in any event the earlier Polypodiiim firmum of Kaulfuss,+ 

 applied to a very different plant from Australia, precludes use of 

 the name. 



There is a specimen in the U. S. National Herbarium no 200650, 

 collected at Songo, Bolivia, November, 1 890, by Miguel Bang no. 

 901 (distributed as P. pliimida) which is identical with the Jamaican 

 plants here described as P. aromaticum ; and it has, moreover, after 

 a lapse of more than ten years the peculiar aromatic odour noted 

 in these. It may indicate a general distribution of P. aromatieum 

 in South America ; but whether or not it represents the P. firmimi 

 of Klotzsch is difficult to say. The name Polypodiiim aromatieum is 

 founded upon Jamaican specimens and is not intended as a sub- 

 stitute for P. firmum Klotzsch. If the plants described by Klotzsch 

 under the latter name shall prove distinct from P. aromaticum, they 

 must necessarily receive a new name. 



Polypodiiim aromatieum may be distinguished easily from P. tigens 

 by its broader lamina, by its fewer pinn^ (these linear and acute- 

 pointed), by the absence of bristly hairs among the sporangia, and 

 in recent specimens at least by the remarkable spicy odour of the 

 fronds. The type specimen bears about 20 fronds. According 

 to Jenman the species is " infrequent on the branches of trees 

 above reach from the ground at 6,000-7,000 feet altitude in 

 forests."
