LiffUSticum.] XXXIV. UMBELLIFEEAE. 205 



16. L. decipiens. Root stout. Scape 3in.— 6iri. high, very slender, 

 simple. Leaves usually radical, spreading-, 3in.-6in. long, linear-oblong, pin- 

 nate ; leaflets in 5—10 pairs, iin.— 2in. long, flaccid, unequally pinnatifid ; lobes 

 linear or often reduced to mere teeth, acute or subacute. Scape naked or 

 with 1 or rarely 2 cauline leaves, sometimes equalling or overtopping the scape. 

 Flowers minute. Umbels iin.— Ifin. in diameter, compound; rays unequal. 

 Involucral leaves dilated at the base. Calyx-teeth acute. Styles slender, re- 

 curved. Fruit narrow-ovate-oblong, not cordate at the base in my specimens ; 

 wings narrow, coriaceous. Pedicels shorter than the carpels. — Angelica de- 

 cipiens, Hook, f., Handbk. 98. Aciphylla decipiens, Benth. and Hook, f.. Gen. 

 PI. i. 916. 



NORTH Island : " I have an imperfect specimen, apparently of this plant, from Colenso," 

 Hooker f. SOUTH Island : not uncommon in the Southern Alps from Nelson to Otago. 2,000ft. to 

 6,000ft. Nov., Dec. 



Closely resembling Ligusticum aromaticum, which is often mistaken for it. Perhaps most 

 readily recognised by the deeply-pinnatifid leaflets with wide sinuses. The wings are usually very 

 narrow. 



17. L. imbricatum, Hook. /., Handbk. 97. Dioecious, forming large 

 flat or convex green patches. Stems stout, much branched, clothed with 

 densely-imbricating coriaceous shining leaves. Leaves ^in.— |in. long ; petioles 

 short, broadly sheathing, the sheath produced upwards into a hooded ligule ; 

 leaflets in 4—7 pairs, sessile, palmate, 4— 5-lohed, each lobe tipped by a stout 

 bristle twice the length of the lobe. Rhachis flattened, broad. Umbels small, 

 simple or compound, hidden amongst the apical leaves. Calyx-teeth acute. 

 Fruit orbicular-ovoid. Carpels with 5 prominent wings. 



SOUTH Island : on high mountain peaks from Marlborough to Southland. 4,500ft. to 

 6,500ft. Jan., Feb. 



In early leafy shoots the produced portion of the sheath is not developed, while the bristle- 

 points are very short and slender. The broad fruits distinguish it from all forms of L. aromaticum. 



18. L. flabellatum, n. s. Polygamous, 4in.— liin. high. Rootstock 

 stout, penetrating the rock to a considerable depth. Leaves iin.— 2in. long, 

 pinnate, linear, very coriaceous ; leaflets in 1—3 pairs, often reduced to a single 

 leaflet, sessile, fan-shaped or rounded -rhomboid, entire or minutely sinuate- 

 crenate ; margins usually involute; sheath very short and broad. Rhachis 

 obscurelv jointed. Scape decumbent, shorter than the leaves, with a small 

 inflated bract above the middle. Umbels small ; rays 3 or 4. General involucre 

 0; partial involucre of connate bracts open on one side; pedicels unequal. 

 Flowers minute, white. Calyx-teeth extremely minute, acute. Fruit almost 

 orbicular. Stylopodia conical at base. Carpels 4- winged or one 5-winged; 

 vittae 4—5. 



STEWART Island: in crevices of syenitic rocks near the South Cape. Jan. 

 Distinguished from all other species by the 3-lobed partial involucres and the almost 

 orbicular carpels. One of the rarest plants in the colony. First observed by Dr. Lyall. 



19. L. Enysii, T. Kirk in Trans. N.Z.I, ix. (1876) 548. Dioecious, 

 depressed, 2in.-3in. high, solitary. Leaves all radical, few, spreading, when 

 fresh excessively thick and glaucous, linear-oblong, pinnate ; leaflets in 3—6
