NEW AUSTRALIAN PROTEACES. 67 
thick valves, which are scarcely concave, and of a somewhat spongy 
texture on the inner side, with one single unripe blackish seed, which 
is 10 lines long, 3 lines broad, lanceolate, tapering at both ends, flat 
and membranous, bordered on one side with a slightly thickened nervi- 
form margin. Evidently this plant, although approaching in habit to 
some Hakeas and Persoonias, especially P. linariifolia, A. Cunn. (P. 
tenuifolia, R. Br.), cannot be inserted in any of the known genera. 
The species may be defined thus :—Strangea linearis, Nob.; glabra, 
ramis gracilibus, foliis sparsis erectis anguste lineari-spathulatis (2 poll. 
longis, 1-23 lin. latis) obtusis muticis planis subenerviis crassiusculis, 
peduneulis axillaribus 1-floris (3 lin. longis crassiusculis) calyce toto 
deciduo . . ., folliculis oblongis compressis utrinque acuminatis.—Of 
the glandule hypogyne no trace could be found.

duis, calycis laminis crispato-villosis, stigmate fusiformi barbato haud 
artieulato basi glabro, nueula compressa obovata emarginata longe

In many points resembling P. Drummondii, but the heads are much 
larger, the flowers more densely tomentose, the seeds broader, almost 
obcordate, and above all, the leaves quite different. 
2. Petrophila circinata, Kippist in litt. ; ramulis pubescentibus, foliis 
longe petiolatis teretibus bi-tripinnatis 4—5-jugis circinato-recurvis 
glabris supra 1-sulcis, segmentis divaricatis semiuncialibus pungen- 
tibus, petiolo basi dilatato, capitulis terminalibus ovatis, squamis late — 
ovatis sericeo-tomentosis, infimis folio nano terminatis, superioribus 
mucronatis, calyce sericeo-villoso (lutescente), stigmate fusiformi his-

It comes very near P. divaricata, but differs in having terminal : 
much larger flower-heads, and the pubescence of the calyx longer an 
more lax, the stigma longer by one-half, obtuse, ete. T
