Norrn Isnanp: From the Three Kings Islands and the North Cape southwards 
to the Bay of Islands, not common, A. Cunningham, Colenso! &e.; Sail Rock (off 
Whangarei Harbour), Miss Shakespear / Oru. December—March. 
In my “Illustrations of the New Zealand Flora’’ I followed Mr. Hemsley in reducing 
the genus Colensoa to Pratia. But, taking into account its much greater size and erect 
habit, the racemose inflorescence and larger flowers, and much larger stigmatic lobes, 
I now think that the genus might well be retained, although its close relationship to 
Pratia must be admitted. 
2, PRATIA Gaud. 126 
Slender prostrate or creeping herbs, rarely ascending or erect. Leaves 
alternate, toothed. Peduncles axillary, 1-flowered. Flowers rather small, 
often unisexual. Calyx-tube adnate to the ovary, limb 5-partite. Corolla 
oblique, split to the base at the back, 2-lipped; upper lip 2-partite, lower 
lip 3-lobed, spreading. Staminal tube free from the corolla or nearly so ; 
anthers cohering, 2 lower tipped with short bristles, 3 upper naked. Ovary 
2-celled ; ovules numerous; stigma 2-lobed or emarginate. Berry globose 
or obovoid, crowned by the persistent calyx-lobes, indehiscent. Seeds 
numerous, minute. 
A small genus of 16 or 18 species, having its headquarters in Australia, but extending 
northwards to the Himalaya Mountains and eastwards to New Zealand and temperate 
South America. It only differs from Lobelia in the indehiscent more or less succulent 
fruit. , ; 
Stems 4-10 in. long. Leaves 4-lin. diam., almost sessile. 
Peduncles usually shorter than the leaves, ¥,.
