Has. Northern Island; south coast and interior, Co/enso. Middle Island, Forster, Raoul, etc. 
This most remarkable plant more resembles Polygonum complevum than any Umbellifer. Mr. Colenso says it 
forms a tangled mass, scrambling over shrubs, etc., a habit quite foreign to any of the Natural Order except 4. rose- 
Jolia. Stems very slender, several feet long, much branched, terete. Branches jointed, flexuose, internodes 2-3 
inches long. eaves with linear sheaths, produced upwards into blunt rounded auricles, Pedioles very slender, 4—4 
inch long. Legflets usually solitary, variable in form, 3-3 inch broad, rhomboid, rounded, or obovate with cuneate 
bases, entire, three-lobed or tripartite, obscurely erenate, finely reticulate. Umbels lateral or terminal, simple or 
compound, of small white unisexual flowers. Fruit membranous, similar to that of 4. rosafolia in form and size, 
large in comparison with the leaves and flowers. —PLATE XX. Fig. 1, umbel of fruit :—natural size. 2, petiole and

Gen. VIII. DAUCUS, Tourn. 
Fructus dorso compressus, oblongus. Carpella plano-convexa ; jugis primariis 5, setosis, 3 dorsalibus, 
2 sutura commissurali impositis; secundariis 4, prominulis, aculeatis; valleculis vittatis. Semen antice 
planiusculum. Calycis limbus 5-dentatus. Petala apice inflexa, exteriora seepe radiantia. Umbelle com- 
posite.  Zuvolucri foliola simplicia v. pinnatifida. 
This large European genus, to which the Carrot belongs, is represented in New Zealand, Tasmania, and South 
Australia by one species, little like the garden plant in appearance, but agreeing in botanical characters very closely. 
It may be recognized at once by its prickly fruit and much-divided leaves. Calyx limb five-toothed. Petals with a 
deep notch and inflected apex ; the outer ones of the outer flowers in each umbel are very large in some species of the 
genus, but not in the New Zealand one. Carpels oblong, with nine ribs, of which four are very prominent, and form 
a series of stiff spines barbed at the apex ; the five intermediate ones (of which two are on the flat inner surface of 
the carpel) are much smaller, and bear each a double row of bristles pointing right and left. (Name, Saveos, in Greek.)

Plants pilose or smooth. Stems many from the root, 6 inches to a foot high, branched, slender in flower, stout in 
fruit. Leaves chiefly radical, with a slender petiole, bi-tri-pinnate ; pinna multipartite, flaccid ; pinnules cut into linear 
narrow segments, 1-2 lines long. Üwöels axillary and terminal, of eight to ten very unequal rays, i-1 inch 
long in fruit. Involucre ; general, simple or multipartite, like a leaf; partial small, of few short linear-subulate rays. 
Petals very small, scarlet. Carpels 1 line long. —A common plant in South Australia and Tasmania; very closely 
allied to a North and South American species, the D. australis, Poepp., D. pusillus, Mx., D. microphyllus, Presl, 
D. scaber, Nutt., as also to D. toriloides, DC., of various parts of South America, from Mexico to Juan Fernandez, 
all which species I agree with Bentham (Plant. Hugel.) and Bunge (Plant. Preiss.) in considering should be united.

apice incurva, pilosa. Umbella simplex; pedicellis floriferis brevissimis, fructiferis seepe elongatis. Invo-
