Flores et fructus ignoti.'' This species, which was first found by Feddersen in the Helga in S. Iceland, grew very abundantly on stones in the Reykirdalsa in SW. Iceland. This river has copious influx from the hot springs, so that, in the first days of June, the temperature of the water was about 12°, which was essentially higher than in the majority of the other rivers where the temperature was, as a rule, only about 4°-6°.. Fig. 12. Fontinalis longifolia (Reykir: somewhat reduced). Fontinalis longi folia agrees most closely with F. hypnoides R. Hartm. The plant from the Reykirdalsa is rather robust, as much as 25 cm. long, very strongly and irregularly branched, with rhizoid-cushions around all the points whence the branches issue, and with plane or somewhat concave, longly tapering, very soft leaves, which only exceptionally are folded along the median line. The J plant is more slender than is the $ plant, with very numerous, narrowly ovate <^ flowers, which often occur in clusters of 2—4 on the main axis and branches and contain each 2—4 antheridia. The fruit, which in the beginning of June was developed to almost full size, but was as yet quite green, so that the peristome and spores could not be investigated, was found scantily on the lowermost part of the stem. As in F. hypnoides the capsule was half-exserted. 33*.
