338 FLORA OF TASMANIA. [4lge, by W. H. Harvey. 
5. Caulerpa Harveyi (Muell.); surculo et parte inferiori caulis nudo nitente, caule vage ramoso, 
ramis paucis elongatis simplicibus densissime foliosis, ramentis (foliis) seepius quinquefariis raro quadrifariis 
longissimis filiformibus patentibus apice obtuse mucronulatis.—Harv. Phyc. Austr. t. 95. ` 
Var. B. erispata ; minor, ramentis crispatis sguarrosis v. inflexis. 
Has. Fragments sent by Mr. Gunn. 
DisrRrB. Native of the south coast of New Holland. 
Surculus branching, 1 or 2 lines in diameter, with a smooth and shining yellow epidermis. Stem 1-2 feet 
high, bare of leaves for some two to four inches above the base; from thence to the apex closely set with five or 
rarely four vertical or slightly'spiral ranks of patent, filiform leaves or ramenta. Sometimes the stem is quite sim- 
ple, but commonly it bears a few lateral, leafy branches, in all respects similar to the leafy portion of the stem. 
Branches long and virgate, patent, irregularly inserted. Leaves (or ramenta) nearly an inch long, as thick as hog's- 
bristle, subacute and somewhat mucronate, of a deep-green colour, becoming olivaceous when dry; the apices, where 
the younger leaves are densely crowded together, frequently orange.—Dried specimens give no clearidea of the living 
plant, as it is impossible to preserve in drying the regular ranks in which the leaves are set, and in which they stand 
parallel to each other. Our var. B is a dwarf form, growing in tide-pools. It is always of a pale-green colour, 
and its ramenta more or less curled, or rolled in upon the axis. 
6. Caulerpa sedoides (Ag. Sp. Alg. i. p. 438; Endl. 3rd Suppl. p. 16; Kütz. Sp. Alg. p. 498). 
—Caulerpa geminata, Harv. Fucus sedoides, Turn. Hist. t. 172. | 
Has. On crevices of tidal rocks: Five-mile Bluff, etc., Gunn. 
Disrrib. Native of tropical and subtropical seas. | 
Sometimes the ramenta are perfectly distichous, in which state I formerly mistook it for a new species, which I 
called C. geminata. I have since traced the two forms into one. Some others of the genus vary in a similar way, 
distichous and tetrastichous ramenta being sometimes found on the same root. 
7. Caulerpa simpliciuscula (Ag. Sp. Alg. i. p. 439; Kütz. Sp. Alg. p. 499).—Fucus simplicius- 
culus, Brown ; Turn. Hist. t. 115. 
Haz. Georgetown, etc., Gunn, W. H. H. 
Disrris. West and south coasts of New Holland. 
8. Caulerpa scalpelliformis (Ag. Sp. Alg. i. p- 437; Kütz. Sp. Alg. p. 496).—Fucus scalpelli- 
formis, R. Br. Turn. Hist. t. 174. 
Haz. Dredged in the Tamar, My. Charles Henty. 
Disrris. West and south-west coasts of New Holland. 
I saw specimens of this species, which is found all along the south coast of New Holland, with Mr. Henty, 
who had dredged them below Georgetown. It has not been sent by Mr. Gunn, and appears to be rare. 
9. Caulerpa cactoides (Ag. Sp. Alg. i. p. 439; Harv. Phyc. Austr. t. 26).—C. corynephora, 
Mont. Voy. Pêl. Sud, p. 18. t. 6. J^ 3; Sylloge Sp. Crypt. p. 452. n. 1600. Fucus cactoides, R. Br. in 
Turn. Hist. t. 171. 
Haz. Southport, C. Stuart. | 
Distrip. Western and southern coast of New Holland ; Isle of Toud. 
S Stuart's specimen is smaller than the usual Australian form, such as we are acquainted with, from Western 
Australia and from Victoria, but it is fully as large as the specimen figured by Montagne. Turner’s Fucus cactoides 
= peii for the larger variety of this species, but it incorrectly represents the club-shaped ramuli as being 
quadrifarious, They are always strietly distichous in our numerous specimens from several localities.
