PLANTS OF VAN DIEMAN’S LAND. 245 
latter are nearly as large, but instead of being of an uniform 
yellow colour the outside is a rich purple, and within near 
the attenuated base of each petal are three distinct depressed 
naked glands; so that we might be almost justified in form- 
ing a new Genus of it. The scape is 8—10 inches high, 
the leaves more than half that length ; the root an oblique 
trunk with numerous fleshy radicles.

1. Pleurandra riparia. Br. in De Cand. Prodr. v. i. p. 12. 
a. glabriuscula ; foliis subscabris nitidiusculis, calycibus glabris.

a, Dr. Scott and Mr. Lawrence (1831.) (n. 224.) Mr. Gunn, 
(n. 32, 22, and 182.)—8. Mr. Lawrence, (n. 225.)—If 
I am correct in this species, it is a very variable one; the 
margins are revolute to the comparatively broad midrib, so 
as to exhibit two narrow lines or striz on the back. The 
surface is sometimes scabrous and glossy, sometimes, as well 
as the calyx, clothed with short soft down. 
9. P. densiflora, n. sp.; pubescenti-hirsuta, foliis lineari- 
oblongis acutis marginibus revolutis (sed non ad costam attin- 
gentibus), floribus sessilibus in ramulis brevibus densifoliis 
congestis, calycibus dorso praecipue sericeis. 
Mr. Lawrence, (n. 22%.)—This is all over downy with 
short appressed hairs: the leaves are much broader than in 
P. riparia, and the flowers are collected, 3 or 4 together, 
upon short ramuli with crowded leaves. din 
3. P.? reticulata, n. sp.; foliis erectis. oblongis coriaceis 
rigidis mucronatis marginibus revolutis supra reticulatis 
areolis depressis subtus appresso-sericeis, floribus sessilibus. 
Mr. Gunn, (n. 125, * A mountain plant.”)—The very few 
flowers on the solitary specimens of this plant are so 1D) ured 
that I cannot satisfy myself with regard to its Genus; and
