NOTES. 
Trichomanes Digitatum, Sw., enters into our list in place of Hym. Corticola, Hk., which Mr. 
Baker finds to be identical with it. The older name therefore prevails. 
Trichomanes Filicula, Bory.—Ceylon specimens of this species have nearly always copious 
spurious venules, stipes winged to the base, and the wing of the stipes ciliated, characters 
not in accordance with the description in the Synopsis. 
Trichomanes Pyxidiferum, L., is a very variable plant both in Ceylon and elsewhere, but 
particularly so in Ceylon. In the southern province specimens are found so small as to be 
mistaken for T. Parvulum. At the top of Telgamma Pass, above Hoolankanda, it has 
been found with fronds three to four inches long, and not more than half an inch broad. 
Between these extremes it is to he found in everv intermediate form. It is distinguished 
from T. Proliferum by the absence of the proliferous character, and by drying flat and 
smooth, instead of shrivelling as that species always does. 
Trichomanes Exiguum, Beddome, was discovered in the Telgamma forests by Mr. T. N. W. 
Beckett, and has since been found abundantly in the southern province and Saff'ragam. 
It is distinguished from very small forms of T. Muscoides, which it strongly resembles, by 
the large, wide-open mouth of the involucre, which is quite free from, and beyond the edge 
of, the frond, and also by long straggling deciduous hairs on the margin. 
Davallia (Humata) Pedata, J. Sm., and Vestita, Blume, seem to he one species, the extremer 
forms of which are so mingled and connected in different specimens that they cannot be 
distinguished by any constant characters. Specimens found a year ago at Ambawella by 
Mr. Wynn combine the characters of both species so completely that they may with equal 
propriety he assigned to either. In the extreme forms of these species, the most obvious 
difference is in the cutting, but in this respect the extremes are completely connected by 
every intermediate form possible. Both species are figured in Hooker’s Sp. Fil., plates 
41 and 45, and in these figures the distinguishing characters (apart from the cutting) appear 
to reside in the form of the involucre, and in the scaly character of the stipes. Beddome’s 
figures also make the species differ from each other in these two characters; hut they are 
inversely referred to the two species by these authorities. Beddome’s figure of Pedata has 
the involucre globose, and that of Vestita funicular. In Hooker’s figures these forms are 
reversed. The form of the involucre may probably depend on the development of the 
fruit within, and be more or less tumid accordingly. A careful examination of many 
specimens, and comparison with the suites of both species at Few, afford no means of 
distinguishing between the two forms by any constant character, or combination of 
characters. 
Davallia Pulchra, Don.—There seems to be some doubt as to this name. Our Ceylon fern is 
that figured in Hooker’s Sp. Fil., plate 51, under the name of D. Cheerophylla, Wallicli. 
Lindsaya Flabellulata, Dry., is not uncommon in the forest of the central and southern 
provinces, and exists in every form intermediate between that of typical Flabellulata and 
typical Tenera. Dr. Thwaites, in his ‘Enumeratio,’ suggests the probability of their being- 
varieties of one species ; and copious specimens collected in different parts of the country 
confirm that view. They are united in the Synopsis.
