CONTRIBUTIONS TOWARDS A FLORA OF VAN DIEMEN’S LAND. 
PITTOSPORE.E. Br. 
l. Billardiera scandens, Salisb.; l. c. p. 
249, should be altered to B. insita Ry 
the fruit being oblong, and quite gla- 
brous. 
To B. longiflora, may be added, as a 
synonym, B. ovalis, Lindl. Bot. Reg. t. 
1719.—The flowers are, very variable in 
size ; some of Mr. Gunn's specimens being 
twice as large as others. The species is 
readily distinguished, both from B. scan- 
sand B. mutabilis, by its almost en- 
tirely glabrous leaves, globose fruit, and 
the straight obtuse petals. 
l. Bursaria spinosa, l. c. p. 249.— Mr. 
Gunn observes that the plant does bear 
spines, not unfrequently ; so that it only 
appears to differ in its much larger size 
from the N. Holland plant. No. “115” 
of Mr. Gunn, should, I believe, have 
been given as No. 
l. Pittosporum bicolor, 1. c. p. 249, is ga- 
thered by Mr. Gunn, on the «omoi 
Hills.

Peduncle short, terminal. Sepals subu-

Backhouse, but the locality is not men- 
tioned.

Mr. Gunn (n. 450.)—Nearly allied to 
S. mecia ; but it is a much larger plant, 
from one to two feet in length, less succu- 
lent. The stems are very glossy, and de- 
stitute of the alternate hairy line which so 
beautifully marks our European plant; the 
flowers are much larger, and the peduncle 
much longer. It bears flowers nearly the 
whole length of the stem. 
S. multiflora, n. sp.—glaberrima, cau-

Mr. Gunn (n. 451.)—A small plant, 
branching diuinis from the root, and 
ecumbent: very distinct from any species 
with which I am acquainted. Every pair 
of leaves produces a flower, for the whole 
length of the stem and branches. The 
petals seem to be wanting in all the flowers. 
Capsule ovate, as long as the calyx, split- 
ting at the apex into six revolute teeth. 
Seeds globose, beautifully dotted and 
tuberculated in lines. 
l. Cerastium vulgatum, L. — Sent with- 
out number or particular habitat. An 
introduced plant, probably.

1. Plagianthus sidoides, Hook, in Bot. 
Mag. t 3396.—Sida discolor. Hook 4. c. 
TG Gunn (n. 452.), who remarks on it, 
that it “flowers in March and April, a most 
unusual season for the blossoming of plants 
in Van Diemen’s Land.” The great simi- 
larity in the piad and inflorescence of 
this with those of Sida pulchella, led 
me at first to refer it to that genus. It 
has now flowered in the Glasgow Botanic 
Garden, and I have no doubt of its belong- 
ing to the little-known genus Plagianthus, 
of which the -—9 two species we are
