slender plant than the preceding. Leaves usually very long, linear, membra-

Leaves 4-fariously imbricate. Flower as large as leaves 2. L. tetragona. 
1. L. depressa. Hook. f. FI. N. Z. i. 177. A prostrate, rigid, woody 
shrub ; branches densely interlaced, puberulous. Leaves •£— J- in. long, coria-

pedicelled, bracteate, solitary or in 3-5 -flowered panicles, male only seen. 
Sepals oblong, obtuse, ciliate. Corolla scarcely longer than the calyx; lobes

imperfect iu my specimens (which are probably unisexual) ; style short, cla- 
vate; stigma oblong, thick. Fruit unknown.

strate ; stem woody, creeping at the base, densely tufted ; branches ascending,
