Rhizome as thick as a crow-quill, 2 - 6 inches long, creeping aud rooting at the joints. Leaves all radical, filiform,
i - 4 inches long, slender, transparent and hollow-jointed, pale green, i - 2 lines broad, in American specimens
sometimes expanding into a flat lamina. Peduncles slender, erect or decumbent, shorter than the leaves.
Umieh simple, few-flowered. Involucral leaves few, much shorter thau the pedicels. Flowers four to ten i
umbel, minute, long-pedicelled. Calyx-lxaRo obscurely five-toothed. Fetals ovate, without an infiexed apex.
Fruit rounded, contracted at the apex ; mericarps semiterete, spongy, not contracted at the commissm-e, five-
furrowed, the ribs thick and convex.— I have stated iu the /F lo r a o f New Zealand’ that I consider tliis plant as
allied to (Enanthe and Ottoa, and not to Hydrocotyle, near ifliich it is doubtfully placed by De Candolle. (Name
in honour of Professor Crantz, author o f a work upon umbelliferous plants.)

I have discussed the subject of the probable specific identity of the southern and northern wild Celeiy in the
‘Flora of New Zealand’ and ‘ Flora Antarctica,’ and pointed out that the thicker and more spongy ribs of the fruit
of the southern species is the only tangible character by which it can be distinguished, and I fear that it is not a
very constant one. In all other respects of size, form, and cutting o f the leaves, powerful or faint aroma, erect or
prostrate babit, both northern and southern form are abundantly variable.— Smooth, glabrous, herbaceous, aromatic,
generally maritime plants, with decompound leaves and erect or prostrate, branching, leafy stems. Umbels many-
flowered, simple or compound, without involucre or involucel. Calyx-]imh obsolete. P e ta h without an inflected
apex. F ru it didymous, lateraUy compressed ; mericarps with five ribs, and one to three vittæ in the interstices.

The two varieties of this plant appear totally dissimilar. The differences are extreme between the short,
broad, obovate, cuneate segments of var. a, and the long, nan-ow, Unear ones of var. fl ; bnt not only are intermediate
foi-ms abundant, but one o f Gunn’s specimens o f fl has leaves o f a occm-ring at the same node with its own.
— A suberect or prostrate herb, sometimes rooting at the joints. Branches a few inches to a foot long, leafy.
Leaves bipinnatisect. Umbels peduncled and simple, sessile and compound.— It would be wortli while to cultivate
this plant, to discover whether, after several years of good soü and manure, it would not become a good Celery. In
the wet climate of Fuegia it makes an agi-eeable raw salad and cooked potherb.

This European genus, to wliich the Carrot belongs, bas but one Australian representative, which is also found
111 the New World ; its prickly, fmit and finely divided leaves at once distinguish it from all other plants of the
same family in Tasmania. The technical characters o f tbe genus reside in the dorsally compressed fmit, with five
primai-y and four secondai-y ridges on each mericarp ; the primary are covered with setæ, and the secondary with
strong prickles.— Calyx-lobes obscure. P e ta h with an incui-ved apex. (Name, SauKos in Greek.)
