Order LXX. Cupuliferæ

Genus 1. Fagus, Linn.

1. Fagus apiculata,986 Col.987 (Fruit.)

Fruiting involucre or cupule, green, ovate, obtuse, 4 lines long, 3- (sometimes 4-) sided, with four imbricated tomentose ovate scales on each side, edges scarious and brown, shortly pedicelled, pedicels pilose; nuts 2–3, broadly ovate, sparsely pilose, outer one (or two) sharply ridged down the centre on one side, inner (or middle) one flat, thin, sub-erose at edges above, tips deeply bifid; styles persistent.

Class II. Monocotyledons.

Order I. Orchideæ

Genus 10. Microtis, Banks and Solander

1. Microtis longifolia,988 sp. nov.

Plant variable in size, and in the number of its flowers; tall, erect, 1 foot 3 inches to 2 feet 3 inches high; leaf solitary terete tubular, with 3 longitudinal furrows from base to tip, 2–3 inches longer than scape, and on open oppressed bract at base 1–2 inches long. Scape stout, 2–3 lines diameter, cylindrical below sub-angular above; raceme 3–6 inches long, many flowered (25–40), flowers pedicelled, small, distant, 2–6 lines apart; bracts 2 lines long, broadly ovate-acuminate, transversely rugulose and decurrent; upper sepal boat-shaped, sub-cucullate, acute; lower pair largely divergent sub-revolute, obtuse; petals free, recurved, obtuse; lip oblong, laciniate or sub-lobed, much crisped at margins; tip broad and bifid; the two lumps at base very large, dark green, smooth and shining; the lump near tip tuberculate or crisped, commonly in two ridges; ovarium stout, 3 lines long, finely papillose, flat beneath, very turgid and gibbous above. [248]

Hab. Skirts of woods near Norsewood, County of Waipawa; flowering in February and March; 1883–84: W.C.

Obs. A species allied to the common M. porrifolia, but differing in several characters (vide descript. supra); and also from its flowering in the autumn. It is nearly allied to some of the Australian species.

Genus 11. Caladenia, Br.

1. Caladenia variegata,989 sp. nov.

Plant erect, 6–12 inches high, glandular-pubescent; pubescence pink-tipped; scape red, sub-rigid not succulent, slender above leaf, stoutish below, arising from a thickened node, having three clasping membranous acute sheaths, one at base enclosing scape and leaf, one at middle 6–8 inches long, and one close under ovarium; root rather long, stoutish, ending in a long white tuber as big as a pea. Leaf single, ½–1 inch from base, 6–8 inches long, 1–2 lines wide, linear-acuminate, thickish, glabrous, channelled, green on upper and purplish-red on under surface, slightly ciliate at edges, and very sparsely pubescent underneath on the lower portion with long weak glandular hairs. Flower single on top of scape, (one specimen only, out of nearly forty obtained, bore two flowers, both springing from within the upper sheath and pedicelled,) perianth spreading, more than ½ inch diameter; dorsal sepal green, arched, sub-oblong-obovate, obtuse and apiculate at apex, produced, glabrous above; lateral sepals pinkish, oblong, apiculate, larger than petals, 3-nerved; petals pink, oblong-lanceolate, apiculate, falcate; lip sessile; disk with two longitudinal rows of bright-yellow stipitate glands having large globular heads, extending from inner part of middle lobe down into the throat, with smaller glands scattered on each side, and one or two at the margin of extreme base of the middle lobe; the two lateral lobes are transversely banded with light-purple, margins white, rounded at tips; middle lobe deltoid, deeply crenulate, recurved, bright yellow; column winged throughout, green, pubescent at top, transversely banded below with light purple, similar to lateral lobes; anther acute, tip subulate, margin finely fimbriate. Ovary 8–9 lines long, linear-obovate, sulcate, densely glandular-pubescent.

Hab. Plentifully, but only in one spot, among mosses on fallen and rotten Fagus trees, and on the ground alongside, in rotten vegetable soil, shady woods, top of a high hill near Norsewood, County of Waipawa; December, 1883: W.C.

Obs. A species closely allied to the two known New Zealand species, C. minor and lyallii; and also to several Tasmanian and Australian species—C. carnea, alata, and angustata; but while serving naturally to unite them differing from them in all important characters. C. minor, [249] which is so common at the north (Bay of Islands), on clayey open hills among fern (Pteris esculenta) and Leptospermum scrub, I have never met with in these southern parts.

Genus 15. Thelymitra, Forst.

1. Thelymitra nemoralis,990 sp. nov.

Plant stout; tubers large, oblong, narrow. Leaf (occasionally two) variable, 6–17 inches long, 6–9 lines wide, linear-acuminate, acute, broadest at base, green, glabrous, thick, strongly 3- (obsoletely 5-) nerved, keeled. Scape stoutish, 8–16 inches long, bibracteate, bracts equidistant, sub-foliaceous, clasping, acute; raceme 2–8- (usually 7-) flowered; flowers distant, bracteolate on rather long pedicels; bracteoles obovate-oblong, acuminate, acute, obsoletely 5-nerved; perianth spreading ¾ inch diameter; sepals pale green with broad white margins, narrower than petals; dorsal sepal much larger than laterals, obovate-oblong, obtuse with a mucro; lateral sepals ovate-lanceolate, acuminate; petals white, sometimes pinkish, broadly elliptic, acute with a mucro; lip similar to petals but narrower and not so highly coloured; column with stout deeply emarginate tip, pinkish below, umber-brown above, edged with bright yellow, margins incurved; appendages produced, rather shorter than column and inclined at top towards it, densely globosely-plumose at tips, white; the base of wings in front of column sub-two-lobed and two-toothed; stigmatic gland bilobed at base, trilobed at apex including rostellum.

Hab. Dry Fagus forests. Seventy-mile Bush, County of Waipawa; 1881–83: W.C. Flowering in December.

2. Thelymitra purpureo-fusca,991 sp. nov.

The whole plant exceedingly slender, of a dusky purple-brown or purplish-red colour; tubers narrow, oblong. Leaf narrow, 1½–3 lines wide, 7–10 inches long, thickish, channelled, glabrous. Scape erect, very slender, almost filiform, bibracteate, 8–10 inches long; raceme 3–5-flowered (occasionally only one); flowers rather distant, bracteolate on long slender pedicels; perianth ½ inch diameter; sepals dark purple-brown edged with a bright green line, a yellow central stripe and broad white exterior margins, sub-ovate-acuminate, much concave, dorsal one largest, the two laterals with a long mucro; petals light pink, sometimes white, elliptic-oblong, obtuse, broader than sepals; lip the smallest; column pink dashed with blue, apex stout, much emarginate, incurved, dark and edged with bright yellow (as in T. nemoralis), but the plumose appendages are more produced and rise above the column; anterior base slightly erose; stigmatic gland similar to that of T. nemoralis; anther very acuminate, tip subulate.

Hab. In Fagus woods on dry hills with the preceding species, but usually higher up; 1881–83: W.C. [250]

Obs. I have both sought and watched this plant very closely; from the fact of its widely different general appearance at all stages from T. nemoralis, and yet, on examination and dissection, I find it possessing such scanty differential characters; the principal ones consisting in its plumose staminodia rising above the tip of the column—its narrower and variegated sepals—its slenderer proportions, dusky aspect and fewer flowers. In all these however it is very uniform; as I have seen and examined (through patiently waiting for their development) some scores of flowers and plants. It has also a peculiar habit of growth, being often found in little clumps (like crocuses and jonquils), from which arise 6–12 scapes. It wears a very striking and elegant appearance, when its dark perianths with their segments edged with white are about expanding, from their contrasts in colour. Notwithstanding the column-appendages being produced beyond its tip, while in T. nemoralis they are below it, this species is naturally very closely allied to that one.
