The specimens from Panama collected by Maxon nr. 5274 (W) are very 
similar to var. bogolensis C. Chr. Revision 306, which differs from typical D. pachy- 
rachis by its pubescent rachis and upperside. Similar more hairy forms occur in 
Ecuador and I think I was right in referring Nephrodium crassipes Sod. and N. 
stramineum Sod. to D. pachyrachis. A third variety is no doubt 
Nephrodium Sprucei Bak. Syn. Fil. 269. 1867. 
Dryopteris Sprucei O. Ktze. Rev. 2: 813. 1891; C. Chr. Index 294. 
Ecuador, Mt. Tunguragua, Spruce nr. 5299, Llalla, Spruce nr. 5299 A, Mon- 
tana de Canelos, Spruce nr. 5301 (all Kew !). 
BakER founded his new species on these three specimens, which were all 
referred to N. resinoso-foetidum by Hooker; they are, however, not quite identical. 
Best agreeing with BakEn's description are nr. 5299 A and 5301. Nr. 5301 is as to 
all characters the eglandulose underside excepted typical D. pachyrachis; nr. 5299 A 
is nearly the same, but the upperside is rather pubescent, the underside and 
indusium sparsely glandular with the characteristic large, red glands, and. the 
coste beneath bear some few thin, brown scales. Nr. 5299 looks very different, 
but it is certainly a large-growing, thin-leaved form of D. pachyrachis. Its pinnz 
are 20 cm long, 3'/2 cm broad, rather densely hairy above, glabrous and slightly 
glandular beneath, the costz rather scaly, and the irregular (sometimes subathy- 
rioid) very large indusia slightly ciliate and glandular by large, red glands. Seg- 
ments 5 mm broad with about 10 veins to a side. 
The var. Jenmani (Bak.) C. Chr. may be specifically different (see Smiths. 
Misc. Coll. 52: 382—383); still it differs scarcely more from the type than do some 
of the Andine forms. The most different form is the large, very thin-leaved and 
densely glandulose variety that I erroneously in “Revision” referred to D. German- 
iana as var. glandulosa. It was also collected by W. Hannis nr. 7485 (B), Jamaica, 
Blue Mountain Peak.
