Dr. W. H. Harvey’s Account of the Marine Botany of 
Order II— LAUEENCIACE^. 
120. Delisia Grey. Eottnest Island, rare (239). 
121. Aspaeagopsis Sanfordiana, n. sp.; surculo valido ramosissimo repente caules plures emit- 
tente ; caulibus erectis simplicibus e basi longe nudis supra ramellis thyrsoideo-penicillatis ; 
penicillis ramellorum quoquoversum egredientibus eximie obtusis; pinnellis oppositis fili- 
formibus crispato-inourvis ; ceramidiis globosis inferne in pedunculo clavato attenuatis. Gar- 
den Island and Eottnest. A very distinct and noble species, mucli larger and more robust 
than A. Delilei, with which, however, I cannot at present further compare it. The much- 
branched surculi are as thick as crowquills; the stems, equally thick, are 3-8 inches long, 
or more, ending in a very dense, deep purple coma. The fasciculi of ramelli are remark- 
ably obtuse in outline. I name it in honour of W. A. Sanford, Esq., Colonial Secretary of 
Western Australia, with whom I had some pleasant sea-side walks, and to whom, during 
my stay in the colony, I am indebted for much kind attention and assistance (124). 
1 22. Aspaeagopsis amata, n. sp. ; surculo ultra-setaceo parum ramoso repente caules plures emit- 
tente; caulibus erectis ramosis usque ad basin ramellis obsitis v. brevissime nudis; ramis 
secundariis consimilibus ad basin armatis ramulis subternis nudis retrorsum aculeatis ; 
penicillis ramellorum subdistichis ambitu ovatis acutis; pinnellis oppositis; ceramidiis glo- 
bosis; pedunculo cylindraceo. Garden Island and King George’s Sound (193). Also from 
Tasmania, B. Gunn^ Esq. Whether this be what I have figured for A. Delilei, in Ner. Austr., 
t. 35, I cannot at present say, not having the book at hand. If not, I at least confounded it 
with that species. It differs from the European plant in having branched stems, feathered 
w'ith ramelli nearly to the base; and in having two or three naked branchlets armed with 
refiexed prickles issuing from the lower side of every main branch, near the base. The frond 
is from 6-10 inches long, twice as thick as hog’s bristle, and of a pale red colour. 
123. Laueencia Forsteri, Grev. On Caulinia stems, &c., very common (103 and 126). No. 126 
is var. /3. data, Sond. A much larger and stronger form than the common one. 
124. Laueencia obtusa. Lx. King George’s Sound and Eottnest, on Algce (67). 
125. Laueencia sp. .. . On rocks. King George’s Sound and Eottnest, near low- water (6). Either 
a larger form of L. obtusa, or a new species. 
126. Laueencia Sond. Cape Eiche (310). 
127. Laueencia arbuscula, Sond. Cape Eiche (309). 
128. Laueencia cruciata, n. sp. ; livido-purpurea, c^spitosa; fronde tereti rigida quoquoversum 
ramosa; ramis ramulisque patentissimis oppositis verticillatisve raro alternis, ramulis juni- 
oribus cylindricis truncatis, fructiferis verrucoso-glandulosis. This requires to be compared 
with L. paniculata, J. Ag., of which I have no specimen. My plant is extremely hard and 
rigid, scarcely adhering to paper after two days’ maceration in fresh water. Agardh com- 
pares his plant with L. obtusa, with which mine cannot be confounded. On Caulinia stems, 
Eottnest (209). 
129. 'LkV'RWCik heteroclada, n. sp. ; densissime csespitosa, e surculis repen tibus orta;- fronde livido- 
purpurea tereti rigida tenaci; juniori pluries secunde ramosa, ramis ramulisque erecto-
