Droseracea. | FLORA OF NEW ZEALAND. 19 
ciliated. Anthers sessile, very broad, with an entire or bifid membranous prolongation of the connectivum upwards, 
and a fleshy erect scale or gland at the back. Female flowers with imperfect stamens, that have the appendages and 
longer connectiva. Ovary flagon-shaped, with a short thick style and four-lobed stigma. Berry scarcely larger 
than a mustard-seed, one-celled, with about three pendulous seeds; žesža coriaceous; radicle cylindrical; cotyledons 
broad and flat.—Imperfect specimens of this plant were originally described as an Hl@odendron : it differs very much 
in habit and appearance from Melicytus, and approaches Hymenanthera in these respects, agreeing also in its discoid 
stigma, few ovules and seeds, and in its very variable leaves, sinuated when young. The plant bears further a close 
general resemblance to Panax anomalum and Melicope simplex.

Sepala 4-5, plus minusve inter se coalita. Petala et stamina 4-5, basi calycis inserta, vix hypogyna. 
Ovarium 1-loculare, stylo brevissimo 3—4-partito v. stigmatibus 3-4 coronato; ovulis plurimis, placentis 
3-4 parietalibus adnatis. Capsula 8-4-valvis. Semina plurima; embryone axi albuminis carnosi, tereti ; 
radicula hilo proxima. | 
Small herbaceous plants, with radical leaves and scapes, or very slender stems, remotely leafy. Leaves in the 
scapigerous species rolled inward in vernation as with the Ferns, always covered with long hairs, tipped with glands 
that exude a viscid fluid, entrapping insects. Sepals five, sometimes united. Petals and stamens five. Ovary one- 
celled, with the ovules generally on three parietal placente. Capsule bursting by three valves, usually surrounded 
at the base by the persistent sepals, and often the petals. Seeds numerous, albuminous; embryo in the axis of the 
seed, with the radicle towards the hilum.—All the species of this genus (eighty-five) have lately been well described 
by M. Planchon (Ann. Sc. Nat. ser. 8. v. 9), from whose monograph it appears that more than half the species 
are confined to Australia and New Zealand. A few of these are common to the East Indies. One of the moun- 
tain New Zealand ones is found in Van Diemen’s Land, and four others are more widely diffused in Australia ; 
the sixth is very nearly allied to the only Magellanic species. There are three kinds in Europe, all found in England 
and in North America. (Name from 8pocos, dew, in allusion to the viscid exudation of the leaves; hence the English 
name “ Sun-dew.") 
1. Drosera stenopetala, Hook. fil.; acaulis, uniflora, foliis longe petiolatis spathulatis, petiolis glaberri- 
mis, scapo elongato gracili 1-floro, sepalis in calycem obconicum 5-lobum unitis lobis rotundatis subrecurvis, 
petalis anguste lineari-elongatis calyce bis longioribus staminibusque perigynis, stylis 3 fimbriato-laceris,

Rhizoma short. Leaves probably very variable in length, as usual in its congeners, in Dr. Lyall’s specimens 
1-2 inches long; the petiole glabrous; lamina spathulate, covered with long glandular hairs. sScapes slender, one- 
flowered, twice as long as the leaves. Calyx an obconic five-lobed cup, 3 lines long, quite smooth. Petals twice 
as long as the calyx and stamens, very narrow linear, almost filiform below, expanding into a narrow spathulate 
retuse limb, membranous. Ovary one-celled, three-valved, with three stigmas, which are divided to their bases into 
many branches. Seeds small, brown-black.—This plant and the D. uniflora of Fuegia and the Chilian Andes form 
a peculiar group of the genus, differing from most others in the one-flowered scape, and from all in the styles being 
divided to the base, and in the stamens and petals being placed on the tube of the calyx. This same species has 
been found in Lord Auckland’s Group by myself, and is alluded to in the ‘ Flora Antarctica ; also by M. Planchon.
