Piddingtonia
ORD. Campanulaceae. A genus comprising about fifteen species of usually slender, prostrate or creeping, rarely tall, ascendent or erect, greenhouse or hardy herbs, natives of Tropical Asia, Australia, New Zealand, and South America. Flowers often rather small, in many species abortive, dioecious; calyx tube adnate, obovoid or turbinate; limb five-parted; corolla oblique, with incurved, oblique or sub-bilabiate lobes; peduncles axillary, one-flowered. Leaves alternate, frequently broad, toothed. For culture, see Lobelia, to which this genus is allied, and from which it principally differs in the fruit being a globose or obovoid berry, and not a dry capsule. P. angulata (angled).* fl. white, nearly 1/2in. long, with the corolla tubular at the extreme base, and oblong, acute limbs; peduncles axillary, slender, 2in. long, ebracteate. Summer. l. shortly stalked, rather thick, sub-orbicular, truncate or rounded at the base, coarsely toothed. Stem creeping, slender, matted, with few large, scattered, spreading, white hairs. New Zealand, 1879. An extremely pretty little creeper for rockwork; quite hardy. SYN. Lobelia littoralis.
P. begoniaefolia (Begonia-leaved). fl. blue, small, on solitary pedicels. June to August. fr. purple, about the size of a Pea. l. roundish-cordate, serrated, petiolate, hairy on both surfaces, oblique at the base. Stems filiform, creeping, hairy. Nepaul, 1827. Greenhouse. (B. R. 1373.) P. repens (creeping).* fl. white, with a violet tint, over 1/2in. long; corolla funnel-shaped, but split at the back; peduncles rather long, axillary, one-flowered. June to October. l. petiolate, rather reniform, undulately sub-crenated. Falkland Islands. A very pretty little hardy plant, well adapted for a sunny position on rockwork. SYNS. Lobelia Pratiana, L. repens.
