Pterostylis Machibbini. 



Leaves all comparatively large, several crowded near the root, or 

 when the stem much heightens all scattered, but the middle leaves the 

 largest, from ovate to lanceolar ; flower of great size, singly terminal, 

 partly chocolate-coloured, slightly puberulous, supported by a large leaf- 

 like bract; upper calyx-lobe and lateral petals upvvards arched, bluntish ; 

 lower calyx-lobes, cuneate-connate below the middle, upwards semi-lanceolar, 

 subulate, neither divergent nor with any long thread-like termination, the 

 sinus betvveen them narrow and very acute ; labellum dark-coloured, 

 glabrous, narrow-elliptical, along the median line upwards folded, its 

 appendage conspicuous fringy-penicillate ; ovulary furrowed.

Flowers here in September. All collectors founds the dwarf form of 

 this species, in which then the leaves are sessile or short-stalked and 

 almost crowded into a rosette, the flower hardly reaching beyond these 

 radical leaves, and being almost sessile among them, the bract expanding 

 into a large floral leaf. Some of Mr. M'Kibbin's speciments from King's- 

 Islands are nearly a foot high, have leaves 3 1 / 2 inches long, on very 

 conspicuous petioles, whereas in some smaller specimens none of the 

 leaves measure over l l \i inches in length. This species differs chiefly 

 from P. curla in the stem, if developed, bearing very expansive leaves, 

 and therefore of far less difference in comparison to the radical leaves, 

 in the larger floral bract, in the more iucurved upper calyx-lobe and 

 lateral petals, and in the far less wide sinus separating the lower calyx 

 lobes. 



Our new plant is distinguished from P. cucullata in flowering under 

 equal circumstances some weeks earlier, in frequently dwarf habit, again 

 in the more cuiwed upper portion of the flower, reminding rather of 

 P. nuta?is, and in the blunt upvvards less narrowed labellum, resembling 

 that of P. obtusa. Besides, from both P. curta and P. cucullata the 

 partly brownish-dark colouration of the flower, not dissimilar to that in 

 P. vittata, distinguish it, although it should be remembered, that Chilo- 

 yloltis Ounnii, Prasophyllum elatum, and Orthoceras strictum vary in this 

 respect as much as could be, green or dark-coloured, whereas in P. vittata 

 the tinge of the flowers is not subject to alterations. 



Incidentally it may here be observed that Mr. M'Kibbin cultivated a 

 plant from Port-Phillip, which, though more robust and bearing larger
