It is difficult to conceive this plant to be a variety of 777. gracilis, but, as Mr. Brown remarks, they are very 
closely allied, however different they may look. It is a remarkably beautiful species or variety as the case may be, 
inhabiting the mountains of New Zealand and Tasmania, differing conspicuously from W. gracilis in the short stems 
and crowded leaves, which, in unbranched specimens, spring immediately from the root, and are spread out on the 
ground in a stellate manner, and in branched ones take the same appearance at the ends of the procumbent 
branches. In this state, and when the scapes are leafless, the plant has a totally different character from any variety 
of W. gracilis; but in some specimens from Milford Sound the stem is drawn out to 6 inches, with the leaves 
scattered along it, and running up the long scape.—Leaves 4-2 inches long, petiolate, linear-spathulate or lanceo- 
late, toothed, sinuate, or entire, with sometimes white cartilaginous margins, often thick and coriaceous in very 
alpine specimens.  Scapes stout or slender, solitary, 3-7 inches long. Ovary turgid. Corolla large, white, 4-3 
inch long, much larger than in any New Zealand specimen of W. gracilis, but smaller than in many common Tas- 
manian states of that plant, four- to five-cleft in New Zealand, four-cleft, according to Brown, in Tasmania. Cap- 
sule rounded.— Much stress is laid, in the ‘Icones Plantarum,’ on the white cartilaginous margins of the leaf of 
the plant there figured, which I consider the same as this, but 77. gracilis itself presents the same character in 
many of its usual states, as described under var. y. littoralis, Br. Prodr. Those who have been accustomed to 
study the varieties of the English Blue-bell (Campanula rotundifolia) will understand how this scapigerous plant, 
with petiolate radical leaves, may become elongated, acquire a branched leafy stem, and bear many terminal pedun- 
culate flowers. I was so far myself misled by this plant as to describe what I now suspect to be a variety of it 
from Tasmania, as a new genus of Lobeliacee! under the name of Streleskia; the latter Order and Campanulacea 
are very closely allied (united by many), and the evident claw terminating two of the anthers in Streleskia induced 
me to place it m Lodeliacee.

Calyx 5-fidus. Corolla ovata v. urceolaris, ore contracta, breviter 5-fida ; lobis recurvis. Stamina 10 j 
filamenta plana, basi dilatata, hypogyna v. imo corollæ inserta; antherarum loculi biaristati. Ovarium 5- 
loculare, basi glandulis 10 liberis connatisve suffultum. Capsula interdum calyce baccato inclusa, 5-locu- 
laris, loculicide 5-valvis. PZacentæ ime columne adnate. Semina angulata ; testa reticulata. 
Rigid, branching, evergreen (sometimes prostrate) shrubs, or small trees, with alternate, coriaceous, reticulated, 
often glossy, toothed or crenate leaves, and often setose branchlets. Flowers axillary or terminal, solitary or in few- 
or many-flowered racemes, white, succeeded by dry capsules or fleshy berries. Calyx quinquefid, often swelling round 
the capsule and enclosing it. Corolla turgid, urceolate, with a small five-lobed mouth. Stamens ten, included; 
filaments flat, dilated below, often hairy ; anther-lobes elongated upwards, where they open by a pore, and are each 
terminated by two bristles. Ovary five-celled, surrounded at the base by five glands, or a ten-lobed dise. Capsule 
small, coriaceous, quite free or surrounded by the persistent calyx, which sometimes becomes fleshy and forms 
a berry. When this is the case, the capsule, though enclosed in the calyx, is free except at the point of attachment,
