tube ovoid ; lobes 3-5, linear, long or short. Corolla A - \ in. long, blue 
purplish or white, 3-5-lobed. Capsule elongate, obconic ovoid or club- 
shaped, 1 in. long, ribbed. — Campanula gracilis, Forst. ; Bot. Mag. t. 691. 
Var. a. Stem tall, generally glabrous. Flowers large. Capsule large, elongate, obconic. 
Var. /8. capi/laris. Stem 1-8 in., covered with spreading hairs. Flowers small or 
minute. Capsule small, ovoid. 
Abundant in dry places throughout the islands, Bonks and Solander, etc., ascending to 
4-5000 ft. An equally abundant and variable temperate and tropical Australian and Pacific 
Island plant, probably not different from an Indian and South African species. 
2. W. saxicola, A. DC.; — FI. N. Z. i. 160. A small, perennial, 
scapigerous, perfectly glabrous herb, 2-8 in. high. Leaves all radical, petio- 
late, 1—2 in. long, spathulate, obovate lanceolate or narrow-linear, shining, 
margins often white, entire or toothed. Scape naked, 1-flowered. Calyx- 
tube turbinate. Corolla oblique, 5-lobed, in. diam., pale-blue. Anthers 
linear-oblong, 1 or 2 of them unguiculate at the tip. Ovary 2- or 3-celled. 
Capsule obovoid. — W. albo-marginata, Hook. Ic. PI. t. 818 ; Campanula saxi- 
cola , Br. Prodr. 
Northern and Middle Islands : not uncommon in hilly au( l subalpine districts, 
ascending to nearly 6000 ft. The Blue-bell of Otago. 
3. W. cartilaginea, Hook, f., n. sp. A small, low, stout, glabrous 
or pubescent herb, 1-3 in. high. Leaves chiefly radical, ^-1 in. long, broadly 
spathulate, obtuse; petioles broad, thickly coriaceous; margins broad, white, 
entire, cartilaginous. Scape short, very stout, erect, naked or 1- or 2-leaved, 
sometimes forked, as if the plant might have a branched stem. Flower large, 
in. diam. Calyx-tube subspheric or obconic, lobes large, linear-oblong; 
margins cartilaginous, longer than the corolla, which is short, broad, and 
included within the calyx-lobes, and 5 -partite almost to the base. Capsule 
turbinate. 
Middle Island: Nelson mountains, in shingle-beds. Rough ; Tarndale, alt. 4000 ft., 
Sinclair ; Clarence and Wairau valleys, alt. 4-6500 ft., Travers. A highly curious little 
species. Calyx sometimes 10-lobed. Flower very sweet-scented. 
2. COLEETSOA, Hook. f. 
A tall, glabrous, milky herb. Leaves alternate, large, membranous, with 
very long petioles. Flowers large, racemose. — Calyx-tube turbinate ; lobes 
5, subulate, equal. Corolla very long, slightly curved, tubular, split to the 
base down the back, 2-lipped ; upper lip of 2 linear-acute lobes, one on either 
side the fissure, lower of 3 oblong, acute, spreading lobes. Stamens exserted ; 
anthers cohering, pubescent, hairy towards their tips. Ovary 2-celled ; style 
bifid; arms spreading; ovules numerous. Berry globose, fleshy and coria- 
ceous, 2-celled, many-seeded. Seeds small, globose, attached to broad, pel- 
tate placentae. 
This fine plant was separated from Lobelia chiefly on account of the baccate fruit. 
1. C. physaloid.es, Hook. f. FI. N. Z. i. 157. Stem flexuose, branched, 
2-3 ft. high, woody at the base. Leaves with petioles 3-6 in. long, ovate, acute, 
doubly serrate or toothed, membranous, glabrous or pilose. Bacemes terminal, 
shorter than the leaves, 6-12-flowered ; pedicels 1 in., bracteolate at the base.
