302 | FLORA OF TASMANIA. [Alge, by W. H. Harvey. 
Has. Georgetown, plentiful, Gunn. 
DisrRrs. West and south coasts of Australia; common in Port Phillip. 
2. Dasya Lawrenciana (Harv. Ner. Austr. p. 60. t. 18.)—Pol, Lawrenciana, Harv. Lond. Journ. 
iii. p. 438. 
Has. Georgetown, rare. 
I have doubts whether this be more than an opaque variety of D. Gunniana. 
3. Dasya capillaris (Hook. fil. et Harv.; Harv. Ner. Austr. t. 19). 
Haz. Georgetown, on the wooden piles of the pier, etc., and on Alge. 
4. Dasya naccarioides (Harv. in Hook. Lond. Journ. iii. p. 432 ; Harv. Ner. Austr. p. 63. t. 22). 
Has. Abundantly at Georgetown. 
DisrRrB. South coast of Australia. 
5. Dasya Tasmanica (Sond.); “caule crasso elongato cartilagineo nudo alterne ramoso, ramis 
subelongatis iterum ramosis inarticulatis, ramulis divaricatis densissime ramellis roseis monosiphoniis 
vestitis, ramellis patentibus dichotomis, articulis diametro duplo triplove longioribus, terminali obtusissimo, 
ceramidiis ovato-subglobosis brevissime pedicellatis.”—Sond. in Linn. xxv. p. 702. 
Has. Tasmania, Stuart. On the Flats, Georgetown, R. Gunn. 
Frond 6-12 inches long, robust, decompound. Branches lateral, elongate, patent, set with one or two series of 
shorter branchlets and ramuli. The main stem and branches are denuded; the shorter branchlets and ramuli 
densely covered with dichotomo-multifid ramuli. The habit is very similar to that of D. elongata, but the ramelli 
are obtuse, not acutely pointed as in that species. —Our specimens are dull reddish-brown, and closely adhere to 
paper. We have not seen an authentic specimen of Sonder's plant. 
6. Dasya hapalathrix (Harv.); caule longissimo (4-6-pedali) glabro repetite decomposite ramoso, 
ramis pluri-pedalibus cartilagineis virgatis crassis sursum attenuatis lateraliter ramosis, ramis minoribus 
bis terve compositis, ramulis ultimis setaceis ramelliferis, ramellis roseo-puniceis monosiphoniis mollissimis 
tenuissimis dichotomis attenuatis axillis acutis divisuris ultimis longissime filiformibus, articulis ramellorum 
diametro 3-6-plo longioribus, ceramidiis subsessilibus v. breve pedicellatis urceolatis ore prominulo, 
stichidiis minutis fusiformibus acutis.—Harv. Alg. Exsie. Austr. n. 201; Phyc, Austr. t. 88. 
Has. In the Tamar, at Point Rapid, W. H. H. 
Disrris. Port Phillip Heads. : 
Frond sometimes 6 feet long, the branches 3 or 4 feet. Stem 1-2 lines in diameter at base, cartilaginous, 
attenuated upwards. Branches lateral, spirally inserted, many times compounded alternately, all the divisions 
virgate, tapering to the apex. The general circumscription of the larger branches is lanceolate, of the smaller, ovate- 
acuminate. The ultimate ramuli are setaceous, about 4 inch long, and are alone clothed with ramelli, which are 
of a bright, purplish, rose-red colour, well preserved in drying. The plant may be immersed in fresh-water without 
injury for a considerable time, a character by which it is readily known from those varieties of D. villosa which 
resemble it in habit. The ramelli, though exceedingly soft and flaccid, may be readily removed from paper, and 
open again in water with facility. 
7. Dasya villosa (Harv. in Lond. Journ. iii. p. 483; Harv. Ner. Austr. p. 61. t. 20). 
Has. Georgetown, etc., common. 
DisrRiB. West and south coasts of Australia, especially in Port Phillip. 
An extremely variable plant in size and ramification, as well as in colour, being sometimes dark purplish-red, 
sometimes bright rosy-purple. It is the softest and most gelatinous of the Australian species, almost instantly de- 
caying in fresh-water, and in this and other respects nearly resembles the northern D. elegans.
