which is so coniraon 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, 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 f inch diameter ; 

 sepals pale green with broad Avhite 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, sp. nov. 



The whole plant exceedingly slender, of a dusky purple-brown or 

 purplish-red colour ; tubers narrow, oblong. Leaf narrow, 1^-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 ^ 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.
