304 FLORA OF TASMANIA. [4lge, by W. H. Harvey. 
inflato-ovatis, ore prominulo, stichidiis minutis oblongis acutis.—Harv. Phyc. Austr. t. 31. D. plumigera, 
Harv. in Trans. R. I. Acad. xxii. p. 548; Harv. Alg. Exsie. Auct. n. 208. 
Has. Georgetown. 
Disrris. West and south coasts of Australia. 
11. Dasya Archeri (Harv.); caule pusillo a basi in ramos numerosos diviso, ramis setaceis elon- 
gatis simplicibus pellucide articulatis polysiphoniis crebre pinnatis circumscriptione ovato-lanceolatis, pinnis 
distichis alternis ramello pectiniformi reflexo-squarroso suffultis simplicibus ramelliferis, ramellis sepius 
alterne geminis divaricato-patentibus pectinato-multifidis (a latere interiore ramosis) mucronatis, articulis 
ramellorum diametro sesquilongioribus. 
Has. Georgetown, rare, Archer, R. Gunn. 
Three to four inches high, divided from the base into numerous branches. Branches as thick as hog’s-bristle, 
pellucidly articulate, often naked near the base, closely pinnated and feather-like beyond the middle. Some of the 
larger branches divide, and each division is then pinnate. Pinne 3-2 inch long, distichous, patent, about a line 
apart, each subtended by a ramellus, which is pectinate on its inner face. Ramelli mostly in pairs alternately, 
robust, patent or strongly reflexed, pectinate, the teeth of the comb horizontal, little tapering, but suddenly mucro- 
nate at the apex. Colour rosy-red.—This looks almost like a small specimen of D. Muelleri, but differs in the 
nature of the ramelli, the greater transparency of the branches, the subtending ramellus to the pinns, etc. We 
have only seen three specimens. 
12. Dasya verticillata (Harv. in Lond. Journ. Bot. iii. p. 434; Harv. Ner. Austr. p. 64. t. 24). 
Has. Georgetown, rare, Gunn, W. H. H. 
13. Dasya bolbochete (Harv. in Lond. Journ. Bot. iii. p. 434; Harv. Ner. Austr. p. 65. t. 25). 
Has. In the Tamar, above Georgetown, common. 
DisrarB. Found at Western Port, Victoria. 
One of the strongest-growing and most bushy of the genus. The figure in Ner. Austr. only represents part of 
a small branch. 
14. Dasya hormoclados (J. Ag. in Linnea; Harv. Ner. Austr. p. 65. t. 26).—Dasya ceramio - 
ides, Harv. Ner. Austr. p. 66. t. 26. 
Haz. Abundant in the Tamar, above and below Georgetown. Southport, C. Stuart. 
DistrIB. South coast of Australia. 
After an examination of a very extensive suite of specimens, I am unable to fix a clear limit between D. cera- 
mioides and D. hormoclados, here united together. 
15. Dasya pellucida (Harv. Ner. Austr. p. 67. t. 27). 
Has. A single specimen at Georgetown, R. Gunn. 
Disrris. Cape of Good Hope, Port Phillip. 
The specimen agrees with those from Port Phillip, but is of a larger size than those from the Cape of Good 
Hope, on which the species was founded. 
16. Dasya crouanioides (Sond.); “fronde continua tenuissima monosiphonia, ramis alternis pa- 
tentibus, ramulis sensim minoribus, omnibus cum fronde primaria fasciculis ramellorum brevissimorum 
verticillatim sejunctorum vestitis, verticillis superioribus confluentibus, ramellis articulatis callithamnioideis 
divaricato-ramosissimis, articulis diametro subduplo longioribus.” —Sond. in Linn. xxv. p. 108. 
Has. Tasmania, Stuart, -
