NortH Isnanp: East Coast, Colenso! Has also appeared as a naturalized plant 
near Wellington. Sourn Istanp: Not uncommon, especially in South Canterbury and 
Otago. Sea-level to 1000 ft. December—March.

5. ©. ambrosioides Linn. Sp. Plant. (1753) 219.—An erect much- 
branched strong-smelling glandular annual herb 1-3ft. high; | branches 
slender, strict, leafy. Leaves shortly petiolate, 1-4in. long, ovate- or 
oblong-lanceolate to lanceolate, acute or acuminate, cuneate at the base, 
coarsely sinuate-toothed or -lobed, membranous, glabrous or pubescent, 
green, not mealy; upper ones gradually smaller, linear-lanceolate, entire 
or nearly so. Flowers exceedingly numerous, very minute, in little clusters 
in slender axillary often elongated spikes, frequently so copiously produced 
as to render the upper portion of the plant a large leafy panicle. Stamens 5. 
Styles 3-4, elongate. Fruiting-perianth about 4 in. diam., segments closed 
over the fruit and completely enclosing it. Seed horizontal or rarely ver- 
tical, smooth, polished, shining, margins obtuse.—Hook. f. Fl. Nov. Zel. i 
(1853) 213; Handb. N.Z. Fl. (1864) 230: Benth. Fl. Austral. v (1870) 162 ;

erect, incurved over the fruit, more or less glandular-pubescent. Stamen 
usually 1. Utricle small, compressed, erect, the pericarp adherent to the
