270 ALGH ANTARCTICA. 
alternis subulatis furcatis vel alterne multifidis, axillis 
acutis, stictis 3-4-vel pluriseriatis. 
Has. Cape Horn. 
Fronds + an inch high, fastigiate, divided from the base 
into many main branches, red-purple. Stem scarcely any; 
branches long, curved, set with simple or multifid ramuli, 
much incurved at the tips. Perhaps’ this is only a variety of 
the last mentioned species, differing chiefly in having an 
abbreviated stem, with longer and consequently more divided 
branches, and a duller colour. 
50. Bostrichia vaga, nobis; caulibus flexuosis vage subdicho- 
tomo-ramosis, ramis paucis simplicibus arcuatis longissi- 
mis nudis, apicibus incurvis, ramulis nullis, axillis po- 
tentibüs, stictis minutis multi-seriatis, stichidiis longis- 
sime pedunculatis lanceolatis acutis. 
Has. Kerguelen's Land. 
Fronds + an inch to an inch in height, densely tufted, very 
flexuose, irregularly branched. Colour blackish-purple. 
Sticte small, disposed in several, 6-8, rows. Very distinct 
in its ramifications. 
51. Bostrychia mizta;* nobis ; caulibus pinnatis, pinnis paten- 
tibus simplicibus vel furcatis, vel alterne ramosis, ramulis 
subulatis patente divaricatis," apicibus strictis vel vix invo- 
lutis, axillis latis. 
Has. New Zealand, on rocks near High-water mark; mixed 
with Gelidium corneum, var. crinale, Caloglossa Hookert, 
and Polysiphonia confinis (n. sp. ined.). 
Tufts widely spreading, intricate. Fronds 3 inch high, 
simple, pinnate; °the pinne’ spreading, simple, or more or 
less branched, sometimes*bipinnate, distant, alternate, acute 5 
the apices straight or the young ones involute. Colour 
blackish-purple. Substance rigid. Sticte in three rows. 
* We introduce this species here, though geographically out of places 
for the sake of contrasting its’ characters with the allied species. Spect- 
mens found at the Cape of Good Hope by myself, and distributed under 
the MS. name of Stictosiphonia Capensis, very nearly accord with the New 
Zealand plant.—J. D. H. ;
