2. L. sisymbrioid.es, Ilook.f., n. sp. Erect, glabrous, slender, a span 
high ; root woody, spindle-shaped, branching out into several heads at the

Stamens 4, glands of the disk 6 or 8, elongated. Pods ovate-cordate, notched

Northern Island. Opuraga, on the beach, rare, Banks and Solander ; Port Nicholson, 
on rocks near the sea, Colenso. Middle Island. Limestone rocks in the subalpine 
region of Waimakeriri, alt. 2000 ft., Haast. I have described the habit, foliage, inflores- 
cence, etc., of this plant, from Banks and Solander’s specimen and drawing ; Mr. Haast’s 
being very young and apparently dwarfed.
