196 CRYPTOGAMIA ANTARCTICA. | Puegia, the 
59. ANABAINA, Bory. 
1. ANABAINA tenaz, Hook. fil. et Harv.; strato globuloso definito lobato gelatinoso fluctuante serugi- 
noso, filis densissime intertextis flexuosis moniliformibus ina:qualibus hic illic interruptis, articulis plerumque 
globosis angulatisve nunc transverse elongatis, majoribus ellipticis oblongis limbo hyalino cinctis solitariis 
plurimisve. Spheerozyga tenax, nobis in Lond. Journ. Bot. vol. iv. p. 298. (Tas. 020111, Fig. IIT.) 
Has. Falkland Islands ; in small pools of water on the hills. 
Stratum 1-3 unc. latum, e massis 1-2 uncialibus conglobatis efformatum, gelatinosum, hyalinum, pulchre 
eruginosum, natans. Substantia gelatinosa, sub lente oculum fugiens. Fila perplurima, dense aggregata, diametro 
varia. Articuli sub lente glauco-virescentes, opacee, majores translucidee. 
A very distinct and beautiful species, evidently congenerie with the Spherozyga Jacobi, of which the Rev. M. J. 
Berkeley has published an excellent figure in the Supplement to English Botany, (t. 2826. fig. 2.) but which we do 
not consider generically distinct from Anabaina. The granular substance of the larger articuli is of a different 
nature from that filling the smaller one, being more transparent, and confined in a proper cyst, between which and 
the border of the articulation there is a transparent space. The stratum is as firm as that of Nostoc ceruleum, and 
the specimens preserved resemble a dried mass of Oscillatoria, 
Specifically this differs from 4. Jacobi in the form of the stratum, and from 4. flos-aque in the straightness of 
the larger articulations.

60. CHROOLEPUS, 4g. 
1. CHROOLEPUS aureus, Harv. in Hook. Brit. Flor. vol. ii. p. 980.  Conferva aurea, Dillwyn, Hist. 
Conf. t. 35. 
Haz. Hermite Island, Cape Horn; Kerguelen’s Land, and the Falkland Islands; very abundant on 
the under surfaces of rocks near the sea, &c. 
One of the commonest vegetable productions in the Antarctic Islands, growing under circumstances where 
no Lichen, or other cryptogamic plant, flourishes. It was always found near the Lecanora miniata, and is very 
abundant in situations sheltered from the direct rays of the sun. When fresh, or rather during drying, it emits 
a very evident smell of violets. 
2. CHROOLEPUS ebeneus, Ag. Syst. Alg. p. 36. Conferva ebenea, Dillwyn, t. 101. Byssus niger, 
Engl. Bot. t. 702. 
Has. Hermite Island, Cape Horn ; in clefts of rocks in the woods. 
Like the former, this species, invariably shuns the light in the south. It was found in damper places than 
C. aureus. Both are, very probably, abnormal states of some Lichen,
