Crantzia. | UMBELLIFERAE. 657 
Norra AND Sourn Is~anps, Stewart IstANpD, CHATHAM ISLANDS: Abundant 
in wet places from the North Cape southwards. Sea-level to 2500 ft. Novem ber- 
February. 
A very variable little plant. When completely submerged the leaves are fistulose 
and terete, softer in texture, and usually much larger; but when growing in places 
that are dry for a considerable part of the year the leaves are often much compressed 
and minute. American botanists maintain that Crantzia of Nuttall is antedated by 
Cranizia of Scopoli, published as far back as 1777, and have adopted the name of 
LiJaeopsis (Greene) in its place...

Erect or prostrate glabrous herbs. Leaves ternately or pinnately divided. 
Umbels compound, leaf-opposed or terminal. Involucral bracts usually 
wanting. Flowers white. Calyx-teeth obsolete. Petals ovate, concave, 
usually inflected at the tip. Fruit ovate or broader than long, slightly 
compressed laterally, constricted at the commissure. Carpels ovoid, with 
five prominent obtuse nearly equal ribs. Vittae 1 under each furrow 
and 2 on the commissural side. 
A genus of about 25 species, widely dispersed in most parts of the world. In 
addition to the two indigenous species, two others have become naturalized in— 
New Zealand—the wild celery (A. graveolens Linn.), which is very closely allied to 
A. prostratum, differing chiefly in the erect habit and thinner ribs to the carpels ; and 
A. leptophyllum F. Muell., a common plant in many warm climates, and which can be 
recognized by the slender habit and ternately divided leaves with filiform segments.
