different-looking papaw is now everywhere cultivated in the tropics for its large fruit, 
which, though insipid, is cooling and antiseptic. , 
The single genus found in New Zealand is endemic and monotypic, and only differs 
from the widely known Passiflora in the dioecious and tetramerous flowers.

Family LXXII. THYMELAEACEAE. 
Shrubs or trees, rarely herbs, inner bark tough and stringy. Leaves 
opposite or alternate, simple and entire; stipules wanting. Flowers 
regular, hermaphrodite or rarely unisexual, in axillary or terminal heads 
or clusters, racemes or spikes, rarely solitary, Perianth inferior, 
gamophyllous, tubular or campanulate, often swollen at the base; throat 
usually furnished with scales or glands; limb with 4-5 imbricate lobes. 
Stamens as many or twice as many as the corolla-lobes (in Pimelea 2 only) 
inserted on the perianth-tube; anthers 2-celled. Ovary superior, 1-celled 
or rarely 2-celled ; style short or long, terminal or lateral ; stigma capitate ; 
ovules solitary or 1 in each cell, pendulous, anatropous. Fruit indehiscent, 
a drupe or nut or berry. Seed pendulous, testa thin or crustaceous ; 
albumen fleshy or wanting; embryo straight, cotyledons fleshy, radicle 
superior. 
A family of moderate size, scattered over most parts of the world. Genera nearly 
40, species estimated at 525. Many of the species are more or less acrid and caustic, 
as the spurge-laurel and mezereum, both of which are used in medicine. The roots of 
several furnish a yellow dye, and the tough inner bark of others is employed for cordage. 
L.agetta lintearia yields the well-known lacebark. Several species of Daphne and Pimelea 
are well-known garden-plants. Of the 2 New Zealand genera, Pimelea is found elsewhere 
in Timor and Lord Howe Island, where there is a single species in each locality, and in 
Australia, where it is largely developed ; Drapetes has a wider range, extending to Australia 
and Borneo on one side and South America on the other,
