160 FLORA OF TASMANIA. SJJmbelli ferae. 
spicuous. Calyx densely covered with imbricating, bullate, membranous, chaffy scales; its lobes ovate, acuminate. 
Petals very deeply notched, the inflexed apex lying flat on the face of the petal, laciniate at the tip.

Distrib. South-eastern Australia, New Zealand, Falkland Islands, and east coast of extratropical 
South America, United States, lat. 30° N. to 42° N. 
Rhizome as thick as a crow-quill, 2-6 inches long, creeping and rooting at the joints. Leaves all radical, fili- 
form, i-4 inches long, slender, transparent and hollow-jointed, pale green, 1-2 lines broad, in American speci- 
mens sometimes expanding into a flat lamina. Peduncles slender, erect or decumbent, shorter than the leaves. 
Umbels simple, few-flowered. Involucral leaves few, much shorter than the pedicels. Mowers four to ten in an 
umbel, minute, long-pedicelled. Calyx-limb obscurely five-toothed. Petals ovate, without an inflexed apex. 
Fruit rounded, contracted at the apex ; mericarps semiterete, spongy, not contracted at the commissure, five- 
furrowed, the ribs thick and convex.— I have stated in the 'Flora of New Zealand' that I consider this plant as 
allied to (Enanthe and Ottoa, and not to Hydrocotyle, near which it is doubtfully placed by De Candolle. (Name 
in honour of Professor Crantz, author of a work upon umbelliferous plants.)

I have discussed the subject of the probable specific identity of the southern and northern wild Celery 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 of the leaves, powerful or faint aroma, erect or 
prostrate habit, 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-limh obsolete. Petals without an inflected 
apex. Fruit didymous, laterally compressed ; mericarps with five ribs, and one to three vittae in the interstices.
