Genus 14. Gnaphalium, Linn.

1. Gnaphalium adhærens,981 sp. nov.

Plant a diffuse bushy perennial herb; main stems woody, as thick as a goose-quill, climbing, adhering closely by long lateral rootlets to perpendicular clayey cliffs. Branchlets sub-secund, patent, drooping, 9–14 inches long, stoutish, covered with floccose silky hairs; leaves alternate, scattered, distant, 2 inches apart on stems, 1½–2¼ inches long, 6–8 lines broad, obovate, acute, apiculate, sessile, half-clasping, margins entire, glabrous above, woolly below, with closely appressed floccose white hairs, membranaceous, flaccid, strongly tri-nerved, light green. Flowers terminal in loose bracteate corymbose panicles, 2–3 inches long, containing 12–13 heads, mostly 3 heads on each sub-panicle or lower peduncle; peduncles and pedicels long, bracteolate, densely woolly like branchlets; bracts and bracteoles foliaceous, margins waved; heads 4 lines diameter; outer involucral scales densely floccosely silky; inner involucral scales 2 lines long, linear, clawed, spreading, lamina white as ligulate florets but narrower, claw green shining thickened at base; ligulate florets white, spreading acute and obtuse, laciniate-toothed at tips; pappus few, slender, scabrid, spreading, not thickened at tips; achenes very small, linear, somewhat subquadrangular, obtuse with a central depression or corona at base, glabrous: receptacle small 1 line diameter, flat, subdepressed, alveolar, full of circular holes with raised margins. [245]

Hab. Damp cliffy clayey sides of the River Mangatawhainui (a feeder of the River Manawatu) near Norsewood, County of Waipawa; 1883: W.C. Flowering in December, with the dead leaves and flowering panicles of the former year still strongly adhering.

Obs. A species allied to G. lyallii, trinerve, and keriense. From its diffuse flourishing growth, peculiar habit, and numerous heads of pure white flowers, this plant looks exceedingly well in its native home. It clings strongly to the cliffs, like ivy, only its rootlets are very much longer, extending some inches each way.

2. Gnaphalium sub-rigidum,982 sp. nov.

Plant bushy, loosely spreading; stems many from one root, woody, ascending, very slender, 12–20 inches long, 1–1½ lines diameter, of uniform thickness, brittle, branched and naked below, simple and leafy above, scarred throughout; bark dark brown. Leaves rather closely-set, scattered or somewhat whorled, patent, sub-coriaceous, linear, 8–12 lines long, 1–1¼ lines broad, sub-acute and apiculate, flat, sessile and half-clasping, glabrous, shining and reddish above, white and cottony below; margins entire, recurved, very thick and shining; midrib stout and prominent below; veinlets anastomosing. Heads of flowers white, numerous, 10–20 at tips of branches, in lax sub-fascicled corymbs, on slender nodding white and cottony peduncles and pedicels of various lengths 3–9 lines long, some 1-, others 2- and 3-flowered, all with long foliaceous narrow bracts, often each pedicel is bi-bracteolate; heads ½-inch diameter; involucral scales white and spreading, oblong, obtuse, rarely notched at tips, margins entire, claw short, greenish-brown, glabrous; florets very numerous, at first yellow, afterwards with a dull reddish tinge; receptacle flat with a raised flat centre, densely and minutely rugged; pappus few, very slender, weak, slightly scabrid and jointed. Achene short, linear, sub-acute at tip, glabrous.

Hab. Dry hilly country west side of Ruataniwha Plains, County of Waipawa; 1884: Mr. H. Hill. Flowering in September.

Obs. A species pretty near to G. keriense, A. Cunn., var. linifolia, J.D. Hooker.

Order LIII. Scrophularineæ

Genus 4. Gratiola, Linn.

1. Gratiola glandulifera,983 sp. nov.

Plant creeping at root, glabrous, stems erect and ascending, 6–12 inches high, simple and branched, stout, semi-succulent, sub-quadrangular, obtusely-angled, deeply channelled on two sides, purple-red, with a few weak and short scattered hairs. Leaves ovate, 4–6 lines long, 2–3 lines wide, obtuse, sessile, half-clasping, thickish, 3-nerved, serrate, sub 6 (generally 4) teeth, teeth and tip dark purple. Flowers few, axillary, solitary, [246] peduncled, peduncles about 1 line long: calyx 5-leaved, leaves linear-acuminate, 1-nerved, green, longer than capsule, obtuse, somewhat knobbed and purple-tipped, each leaflet having a row of sub-succulent white hairs down the nerve on the outside: corolla ½ inch long, pubescent, limb white; upper lip 2-lobed, sometimes purple-margined; lower lip 3-lobed, lobes all very obtuse; tube yellowish, purple-striped, throat above thickly clothed with golden glandular hairs, and on each side a single row of similar hairs. Capsule broadly-ovoid.

Hab. In boggy spots, edges of water-courses near Norsewood, County of Waipawa; 1884; but very local; flowering in March: W.C.

Obs. A species having pretty close natural affinity with G. sexdentata, A. Cunn. (? G. peruviana, Benth.), but apparently differing in several characters, the chief one being the thick glandular pubescence lining the corolla.

Genus 9. Ourisia, Comm.

1. Ourisia robusta,984 sp. nov.

Erect, glabrous, scape, sparingly pilose.

Leaves radical broadly-ovate, obtuse, deeply crenate or sub-crenate-serrate, teeth apicular, each with a gland-like circular brownish dot on upper surface within margin, triple-ribbed, veins very stout and prominent below, lamina 6 inches long, thickish, slightly decurrent; petioles same length, thick, sub-succulent, deeply canaliculate, edges purple and slightly hairy. Scape 1½–2 feet high, very stout, 5 lines diameter, septangular and sulcated, purple-striped, bearing long white jointed and weak hairs scattered on its angles. Bracts, or floral leaves, on the scape all whorled, lowermost 5–8 (generally 8), broadly lanceolate, 2½ inches long, serrate, margins purple, 5-nerved to base of petiole; petioles long broad and flat, edges hairy; upper whorls of bracts very numerous (00), serrate, decreasing gradually in size to the apex. Flowers umbelled in distant whorls, generally nine; pedicels 1½ inches long, rather slender, sub-angular, purple-striped, covered with thick glandular pubescence; calyx 5-partite, glabrous, purple-striped, lobes linear-subulate, 1-nerved, 5 lines long, obtuse and thickened at tips; tips recurved, margins purple; corolla large 11 lines diameter, white within, purple and purple-striped on the outside; throat yellow-green, densely clothed with numerous jointed and sub-clavate succulent hairs of the same colour; tube short 3 lines long; lamina spreading 5 lines long, lobes large, retuse, veined; veins obtusely angled and rounded. Capsules orbicular-oblong, broadest at base, turgid, glabrous, purple-spotted on top, much smaller than calyx lobes.

Hab. In gullies on the high lands west of Napier, between Napier and Taupo; 1883: Mr. H. Hill. [247]

Obs. I. This species has close affinity with O. macrophylla, Hook., but differs from it in several particulars; the sepals are narrower longer glabrous and coloured, and only 1-nerved; the corolla is coloured within and there clothed with densely glandular pubescence, and the tube is much shorter, and in the venation of the limb, which is also larger, the angles are rounded at apices, and not acute as in that species, and the pedicels are densely glandular-hairy: the leaves also are different, both in their shape and in their curious little gland-like openings or depressions on their margins; and the scape is very much stouter and 7-angled, with its lower floral leaves much more numerous, larger and petiolate.

Obs. II. From Sir J.D. Hooker’s “note”985 on an imperfect specimen of Ourisia of possibly an additional species allied to O. macrophylla which I had early “gathered near Taupo;” I am of opinion that this may very likely be identical with that plant.
