970 Diolazium crenulatum Bale,, var, -rllS— '* 
Re, re in naayp, shady glens above Onaca, 3500-4000 ftj 1 have found it^WVya 
only on roc-lee near cascades. This may be a variety of No. 938, due to 
situation; but it is much broader in form, the lower segments little de- 
cirtscen’t, , segments larger end rachis end veins less hairy. Compere No,,

971 Rare on banks in forest or sha.dyyfplac es , below 1500 ft. Specimens wx- 
were collected near Masinga, 500 ft, l?ov», 50 specimens,. 
971 Specimen collected 4 miles east of Bonda, 400 ft. Nov, 12, This spe- 
cies is local end rare, generally below 2000 ft,; I have found it on a 
hill overlooking the sea end not more than 150 ft, above sea-level. 
Commonly it is associated with 2558, or 969, or both; but it is al- 
ways easily distinguishable,. 
972 Aspienium pumilum Swse,. 
Local on sheltered banks in the dry forest region, ranging from ,2500 ft,, 
nearly to sea-level; it appears only during the rainy season. Specimens 
were collected near Onaca, 1800 ft, Dec, 50 specimens,. 
9?3 Asplcnium deuterium Swz, var,. 
Common in damp forest, 1200-3000' ft. Specimens are from Mamacasacj^ 2000 
ft. May. Commonly two lower segments ere somewhat shorter and below 
these there may be one or more pairs of very short or abortive segments, 
but the. latter are often wanting, and in some causes the lower segments 
are the longest, 24 specimens , 2 or 3 roots poor. Foots for N»Y. & Car_ 
negie. 
974 ( var. of 973 ?) 
Mountain forest, 4000-6500 ft, principally in damp ravines, on rocks. Num- 
erous specimens from different localities differ constantly from No. ,975 £ 
i> in having the secondary segments deeply parted or divided, giving the t 
leaf a more finely cut appearance. The lower segments are always much 
decrescent with a number of very short segments ; the latter are commoner 
wanting in No,. 973, as I have found no intermediate forms, it would 
appear that the ferns are separable, at least as varieties. 
No 974 occurs in very damp situations; 973 in comparatively dry one§ 
on mountain -sides. Specimens are from Las Nubes, 4500 ft. Feb, 
23 specimens mostly with roots, 
9 75 Aspienium rhizophorum tri pinna turn Hook- 
Don Amo ^fountain forest, principally in ravines, 5500-6590 ft; common lo- 
cally. Specimen is from Las Nubes, 4500 ft, Feb, very variable, and the £ 
different forms are sometimes pretty constant; but the distinctions 
break down when large numbers of specimens are examined. I have given &m 
numbers to three of these varieties, but thyy can only be regarded as ex 
treme forms, the differences being , perhaps , due to situation. The species 
grows in the ground or on rocks. 31 specimens. 
975 Specimen from the Sierra- del Libano, 6000 ft, in a- damp ravine, March 
Passes into 11.27 
975 Specimen from Las P aril das , 5500 ft. March, This is a common form 
below; 5000 ft. and also occurs higher up. It passes into Nos. 976, & 973 
976 Aspienium rhizophorum bipinnatum 
Mountain forest, 3500-6000 ft.; Common principally in very damp situations 
near streams etc. grows ^on the ground, some times on rocks or trees. Speci- 
men is from the Sierra del Libano, 5590 ft. March. 13 specimens,.
