14 CONTRIBUTIONS TO QUEENSLAND FLORA. 
NOTHOLASNA, R. Br. 
N. sciadioides, Domin in sched. Czspitose, but the fronds 
not numerous, loose, long-stipitate. Stipites slender, erect, 
subnitidous, quite glabrous, 34-4}in. long. Fronds (without 
the stipes) about 2-3 in. long and 13-2} in. broad, deltoid sub- 
tripinnate. Rhachis very slender, the lower part fusco- 
castaneous, the upper part greenish ; pinnz glabrous on both 
sides, all except the uppermost petiolulate. Lowest pinne 
about 14 in. long, ovate-deltoid, pinnate, apex pinnatifid, the 
outer basal pinnule about 6 lines long and pinnate or the apex 
lobed; the medium pinne about 1 in. or less long. Sori 
paucisporangiate, few. The margins of the pinnules flat or 
obscurely subrevolute.—Cheilanthes sciadioides, Domin, 
Prodr. p. 135. 
Hab. : Picnic Creek, Russell River, K. Domin. 
The present plant, along with N. fragilis, Hook., N. 
Prenticei, Luers., and N. glabra, Brack., might all be included 
as forms of the oldest known species, N. glabra, Brack. 
PLATYCERIUM, Desv. 
P, alcicorne, Gaud., var. subrhomboideum, Domin, Prodr. 
p. 198 (under P. bifurcatum, C. Christens.). 
P, alcicorne, Gaud., var. lanciferum, Domin, Prodr. p- 198 
{under P. bifurcatum, C. Christens.). 
P. grande, J. Sm., var. tamburinense, Domin, Prodr. p. 200. 
It is scarcely advisable to attach names to isolated plants 
of Platycerium, particularly as differences in their growth and 
form are so often caused by situation.
