to be the Malayan Asplenium longissimum Bl.; from this 
species our plant differs, however, in almost all characters 
with the single exception of the long proliferous tail. Nei- 
ther JoHow nor SkoTTSBERG have seen fertile fronds, still 
it is without question that the species belongs to the genus 
Blechnum § Lomaria. It is evidently a very near ally of B. 
Sprucei C. Chr. (Lomaria caudata Bak.) from the Andes of 
Ecuador, but as to several points the descriptions of BAKER 
(Syn. Fil. 179) and Soprro (Cr. vase. quit. 119) do not agree 
with our species, which is much larger (pinne in B. Spucez 
only 5—7 em. long) and with acuminate pinne auricled on 
both sides of the base. — The proliferous leaf examined mea- 
sures from base to apex 2 m., the tail from the lowermost 
bud 1 m., the lamina of tbe non-proliferous leaf 50 cm. 
Dr. SKOTTSBERG has collected some seedlings of three 
species of Blechnum § Lomaria, which differ so much from 
each other that I shall describe them shortly. Seedlings 
of ferns are seldom mentioned in the literature, but it seems 
that a study of them can give us some contributions to the 
right understanding of the natural relation between the spe- 
cies of a genus. The three species are: 
1. B. magellanicum (Desv.) Mett. var. setigerum (Gaud.) 
— Fig. 1 a, b. Rhizome horizontal or oblique, clothed with 
thin, yellowish, ovate scales. Leaves entire, ovate-lanceolate, 
acute, on long stalks, which are glandulose by stalked, capi- 
tate glands. Margins crenate or undulate, texture very thin, 
transparent; veins very distinct, forked, terminating in a ca- 
pitate apex within the margin. The leaf resembles very much 
a barren frond of a species of Hlaphoglossum. 
Found in a dark crevice on Westpoint Island, West 
Falkland. 
2. B. chilense (Klf.) Mett. Fig. 1 c. Rhizome erect, cloth- 
ed at the top with numerous brownish scales. Leaves in 
rosette on short stalks, which are glandulose as in the for- 
mer species, the youngest almost orbicular, the elder ones 
ovate, acute, fully entire, thick, coriaceous; veins obscure, 
forked, not reaching the margin. — Chiloé. 
3. B. penna marina (Poir) Kuhn. Fig. 1 d. Rhizome
