1. Anopterus glandulosus (Lab. Nov. Holl. i. 86. t. 112).— DC. Prodr. iv. 6 ; Hook. But. Mag, 
4317. {Gunn, 524.) 
Hab. Abundant in many, and especially subalpine, parts of the Colony, growing in forests : Port 
Arthur, Recherche Bay, Hampshire Hills, etc.— (Fl. Sept.-Nov.) (v. r.) (Cultivated in England.) 
One of the most beautiful Tasmanian plants, both from the richness of tta <l;irk green, glossy foliage, and 
abundance of drooping racemes of white flowers. It usually forms a shrub C-10 feel high, extremely like Ccnnrrheu^ 
nitida in general appearance (Gunn) ; but in the Acheron Valley, on the road to Maeanarrie Harbour, Ghmn ooUeeted 
specimens from trees 30-40 feet \ugh.— Leaves chiefly at the ends of the branches, spreading. '■'>- * 
lanceolate, acute, tapering to a short petiole, coarsely, bluntly serrate, very coriaceous. Hacimes tenninal, sonu liitu - 
panicled at the base, nodding, 3-6 inches long, many-flowered, surrounded with short, imbricati bracta ai the baa 
Bractlets at the base of the pedicels, deciduous; pedicels | inch long. / 
conical at the base, with six short, acute, spreading segments. Petal* six, obovate-obl 
with the petals; filaments subulate, shorter than the petals ; mitlwr* cordate. Onny conical, two-celled, with many 
paiietal ovides, tapering into a short style and bifid stigma. Capsule* on spreading, elongai d. rigid pedicels, sur- 
rounded at the base with the calyx-tube, one-celled, two-valved ; valve- recurved. Sue/Is vi r\ numerous, imbricated. 
winged. (Name from avw, upwards, and irrepov, a wing ; in allusion to the ascending wing of the seed.) 
Nat. Ord. XXXYIII. UxMBELLIFEILE. 
The Australian UmbeUifera are not numerous, but very peculiar, chiefly belonging to sections of the 
Order which are sparingly found in the northern zone. About 120 species are known, and half of these 
are confined to the eastern parts of the Continent, but few are common to both sides, and about 50 are 
exclusively South-west Australian. 
Gen. I. HYDROCOTYLE, Town. 
Fructus a latere plano-comprtH is limbo truncato v. obsolete 5-lobo coronatus j 
mencarpiis evittatis, jugis filiformibus, dorsalibus et inarginalibtis, >w\m obs ns,j termed - luobus intr-nliim 
accretis. Petala ovata, integra, apice recto. — Herbaj repentes, tenelke ; ombellifl 
simplicibus ; involucro oligophyllo. 
The Australian Hydrocotyles are all slender, creeping marsh-plants, with solitary 
the nodes, and solitary, erect peduncles, bearing simple umbels of very minute white or greenish flowers. — Calyx- 
limb obsolete, or five-lobed. Petals five, generally acute, without an inflcxed point. Stamens live. Carpels didy- 
mous, much lateral!) compress) d, gi nerally with one or more semicircular ridges down each face, often enclosing a 
small hollow.— About twenty Australian species are known, most of them being peculiar to that continent. (Name 
from iSoip, water, and kotvXt), a cup ; in allusion to the form of the leaf of the European species.)
