366 5. B. diversifolia, ''Petrie in Trans. N.Z. Inst.'' xix. (1887) 324.—A slender erect annual herb l–2½ ft. high. Stems grooved, glabrous or slightly cottony, simple or branched above. Leaves erect, 2–4 in. long; lower oblong or linear-oblong, narrowed into long petioles, obtuse, rather membranous, glabrous above, often puberulous beneath, entire or remotely and minutely denticulate; upper narrower, linear or linear-lanceolate, acute, sessile or nearly so, not auricled, glabrous or slightly cottony. Corymbs laxly and h-regularly branched; pedicels slender, bracteate. Heads ¼ in. long; involucral bracts 12–14, linear-lanceolate, acute. Florets 30–40; females much the most numerous. Achenes linear-oblong, grooved, hispid, crowned with a callous ring.—Kirk, Students Fl. 335.

6. E. glabrescens, ''T. Kirk in Trans. N.Z. Inst.'' ix. (1878) 550.—A slender erect annual 1–3 ft. high; stem grooved, simple or branched above, glabrous or nearly so. Leaves very variable in size and shape, 3–6 in. long, oblong or lanceolate-oblong, deeply pinnatifid with the segments irregularly sinuate-dentate, or pinnate with a large terminal leaflet and few or many much smaller lateral ones, lower petiolate, upper sessile with broad toothed auricles, membranous, often purple beneath, glabrous or nearly so. Corymbs lax. Heads ⅓ in. long; involucral bracts 10–12, Imear, acuminate, green with white margins. Florets 20–30; females the most numerous. Achenes longer than any other New Zealand species, $1⁄8$–$1⁄7$ in. long, pale, linear, glabrous, obscurely grooved, attenuated above, crowned with a callous ring.—Students Fl. 335.

Shrubs or small trees. Branches stout, spreading, densely clothed with white tomentum, as are the leaves beneath and branches of the inflorescence. Leaves large, irregularly lobed or sinuate. Heads small, very numerous, crowded in large much-branched terminal panicles, heterogamous, obscurely radiate. Involucre narrow; bracts in 1 series, linear, scarious, shining, usually with minute subulate scales at the base. Receptacle small, foveolate. Florets of the circumference female, irregularly lobed or
