STYLIDIUM MUCRONIFOLIUM. 
Bristle-pointed Stylidium. 
‘Nat. Ord. StyLipIE#.—GYNANDRIA DIANDRIA. 
Gen. Char. (Vide supra, Tas. 4529.) 
Srytip1um (§ Nitrangium) mucronifolium ; caulibus brevibus inferne ramosis, 
foliis glabris lineari-subulatis setaceo-mucronatis, scapis vel pedunculis 
terminalibus nudis superne paniculaque glanduloso-pilosis, corollis luteis 
aurantiaco-pictis, labello utrinque appendiculato, ovario cylindraceo-elongato. 
Sryzrprum mucronifolium. Sond. in Plant. Preiss. v. 1. p. 383. 
Raised by Messrs. Lucombe and Pince, from Swan River seeds, 
and communicated to us by that firm under the name here 
adopted, and by which is doubtless intended the plant so called 
by Sonder, with which, however, it does not wholly agree, for 
neither is the labellum in our plant “inappendiculate,” nor can 
the leaves be said to be “radical.” The first character is, 
indeed, easily overlooked in the dried plant, from which Sonder 
was likely to have drawn up his description ; and with regard 
to the latter, tufted rosules of apparently radical leaves do, in 
several Stylidia, elongate into real leafy stems or branches. 
Again, the nearest natural allies of our plant are unquestionably 
S. ciliatum, Lindl. (Bot. Mag. t. 3883), and 8. saxifragoides, 
Lindl. (Bot. Mag. t. 4529); but Sonder has separated them by 
nearly thirty species ; the two just mentioned belonging to the 
section Tolypangium, Endl., our present plant to the § Nitran- 
gium, Endl.:—two groups only distinguishable by the more or 
less elongated ovary or capsule—assuredly a very artificial cha- 
racter. Our species is very pretty and produces its copious 
bright tufts of flowers in August. 
Descr. Roots wiry, brown. Stems in our plant tufted, two 
to three inches long, copiously leafy. Zeaves glabrous, patent, — 
linear-subulate, broader at the base, tipped at the point with a 
setaceous mucro. Peduacles, rather than scapes, terminal, soli- 
tary on each branch, a span high, above, and the pedicels
