Bucuanan.—On some New Species of Plants. 243 
Mueller, in his criticism of the genus (Chatham Island Flora), thinks it 
probable that some of them may have been describing varieties of the species. 
Dr. Hooker, again, in not recognizing more than one species, seems to consider 
the others not founded on sufficient data. It is, therefore, with some 
hesitation that the present is advanced as more than a variety. The differ- 
ences, however, between this plant and Arundo conspicua are so great, 
particularly in its low habit of growth and dense-flowered, erect, fulvous 
panicle, that it has for many years attracted attention, and indeed some 
species of Agrostis and Poa rest on less distinction. 
Collected by Dr. Menzies on the Mataura River, VENE in 1867 ; and x 
J. Buchanan at Wellington Heads, in 1873. 
Senecio robusta, n. s. 
A small, woody, robust shrub, branches covered with scales formed by the 
sheathing bases of the old petioles, leaves below and petioles covered with 
thin, appressed, buffy white tomentum. Leaves petioled, 1— -1i inch long, 
oblong ovate, or obovate and acuminate at bottom, rounded at top, margin 
entire, glabrous, and wrinkled above, coriaceous, the two lower nerves 
springing from near the bottom and running parallel with the margin for 
three-fourths of the leaf's length. Petioles 1—1 inch long, flattening into 
sheaths at bottom, corymbs erect, spherical, of 5—7 yellow heads on robust, 
erect, terminal, bracteate peduncles ; bracts linear, - obovate, petioled ; 
bracteoles nearly as long as the pedicels, very narrow, linear, acuminate, 
peduncle, pedicels and bracts below covered with appressed tomentum, Heads 
campanulate, $ inch across; involucral scales in one row 1 inch long, linear ` 
acuminate, borders membranous, sparsely woolly, and terminated by a small 
tuft of hairs ; rays 1 inch long, revolute ; anthers tailed ; pappus hairs in oue 
row, white, scabrid. Achene glabrous, slightly grooved. 
Collected by Mr. J. Morton on Mount Eglinton, Southland, 1873. 
Plate XXII., fig. 1— Plant nat. size. 
Allied to uo monroi and Senecio laxifolia, but differing very much from 
both in habit of growth, very coriaceous leaves with peculiar venation, and 
small robust corymbs of few large heads of flowers. 
Carex appressa, Brown. 
New to New Zealand. 
Collected by Dr. Hector in Milford Sound, January, 1873. Hitherto 
found only in the Auckland and Campbell Islands. 
Rubus parva, n.s. 
A small, prostrate shrub, branches rooting, smooth, unarmed. Leaves 
simple, alternate, petiole 1 inch long, leaves 1-2 inches long, l inch broad, 
linear, deeply serrated; back of mid-rib with 2-6 large, nearly straight spines ; 
petioles, mid-rib, and bottom of serratures with a few scattered stiff hairs.
