Crantzia.] xxxiv. umbelliferae. 199 



corky ribs separated by narrow furrows, a vitta under each furrow and 2 on 

 the commissure. A small creeping herb, with solitary or tufted erect cylindrical 

 leaves springing from the nodes, and simple few-flowered axillary umbels. 



A monotypio genua, extending to Australia, extra-tropical North and South America, and the 

 Falkland Islands. Named in honour of Henry John Crantz, an Austrian botanist. 



1. C. lineata, Nutt., Gen. N. Am. PL i. 177. Rhizomes slender, rooting 

 at the nodes. Leaves Jin.— 5in. long, linear-fistular, internally septate, obtuse, 

 sometimes compressed. Peduncles axillary, solitary, filiform, 2— 6-flowered. 

 Involucral leaves minute. Pedicels 1—3 lines long, capillary, spreading. Disk 

 confluent with the conical base of the style. Fruits 1—2 lines long. — Hook, f., 

 Fl. Antarc. ii. 287, t. 100; Fl. N.Z. i. 87; Handbk. 89. Hydrocotyle lineata,

From the North Gape to STEWART Island ; CHATHAM Islands. In wet places, especially 

 near the sea ; rarely in running water. Ascends to fully 2,000ft. Nov. to Feb. 



The leaves are usually compressed when growing in elevated situations. 



8. LIGUSTICUM, Linn. 

 Calyx-teeth usually obsolete or minute, sometimes unequal. Petals in- 

 flexed at the tip. Stylopodium conical. Fruit linear-oblong, elliptic-oblong, or 

 ovate-oblong. Carpels dorsally compressed, each with 5 equal winged ridges, or 

 one or both carpels with 3 winged ridges ; vittae often obscure. Glabrous or 

 rarely pilose or silky erect perennial herbs, from lin.— 4ft. high, often robust, 

 aromatic or strong-smelling, with pinnate or decompound leaves, the rhachis 

 jointed at its juncture with the leaflets. Umbels polygamous, compound or 

 rarely simple, often panicled. Flowers white or red ; female sometimes on 

 very short pedicels. Herbs, often of large stature, with pinnate or decompound 

 leaves. 



Much uncertainty exists as to the limits of this genus. Benlham restricts it to species of the 

 Northern Hemisphere in which vittae are well developed, and unites those of the Southern Hemi- 

 sphere with Aciphylla, in Genera Plantarwm. I prefer to follow Hooker in placing them under 

 Ligusticum, although it might be better to restore the genus Anisotome for their reception. All the 

 New Zealand species of this section are endemic. Two or three otliers ace found in South America, 

 and one in Tasmania. Name from Liguria, the home of the officinal species.
